Bertha is a Legendary Lancer hero in Whiteout Survival who combines healing, team buffs, enemy control, and strong Expedition damage support. Unlike many Lancers that focus mainly on personal damage, Bertha can restore the Health of friendly heroes while increasing their Attack.
Her Expedition skills improve Squad Lethality, strengthen repeated Lancer attacks, buff friendly Marksmen, and make enemy targets take additional damage. This gives Bertha value in Exploration, Arena, Bear Hunt, offensive rallies, city defense, and large-scale PvP.
This Whiteout Survival Bertha guide covers her stats, skills, shard requirements, exclusive gear, best uses, upgrade priorities, and investment value.
Bertha Overview
Bertha is a Generation 17 Legendary Lancer hero with the Combat subclass. Her kit combines formation healing, Attack buffs, immobilization, normal-attack damage, Squad Lethality, and enemy damage amplification.
| Detail | Bertha Information |
|---|---|
| Rarity | Legendary |
| Class | Lancer |
| Subclass | Combat |
| Hero Generation | Generation 17 |
| Main Role | Healing, damage support, and enemy debuffs |
| Best Modes | Exploration, Arena, Bear Hunt, rallies, city defense, and PvP |
| Exclusive Gear | Adjudicator |
| Main Strengths | Team healing, Attack buffs, Squad Lethality, and Weakness debuffs |
| Main Weakness | Limited personal protection and several effects depend on repeated attacks |
Bertha’s Exploration kit makes her a hybrid support and damage hero.
Healing Rain restores Health to the full formation and temporarily increases friendly Attack. Tranquilizer damages and immobilizes an enemy, while Enhancement Reagent increases Bertha’s normal-attack damage.
Her Expedition skills are heavily focused on damage. Dissection increases Squad Lethality, Vengeance empowers every second Lancer attack while buffing Marksmen, and Lethal Precision increases Lancer damage while making targets take more damage.
Bertha can therefore support both Lancers and Marksmen while improving the damage of the entire formation.
Bertha Stats
Bertha has balanced Exploration Attack and Defense, supported by a large Health pool. Her Expedition stats provide equal Lancer Attack and Defense bonuses.
Exploration Stats
| Stat | Maximum Value |
| Attack | 44,376 |
| Defense | 44,376 |
| Health | 443,778 |
Bertha’s equal Attack and Defense stats support her hybrid role.
Her Attack is especially important because Healing Rain calculates its healing from Bertha’s Attack. Increasing her Attack improves both her personal damage and the amount of Health restored to friendly heroes.
Her Attack also improves:
- Tranquilizer damage
- Normal attacks
- Enhancement Reagent’s practical damage value
- Exclusive gear effects that scale with Attack
- Healing Rain’s Health restoration
Bertha’s Defense and Health help her survive enemy area attacks. However, she is still a Lancer and should usually remain behind a durable Infantry frontline.
Expedition Stats
| Stat | Maximum Value |
| Lancer Attack | 2,301.84% |
| Lancer Defense | 2,301.84% |
Bertha’s equal Expedition bonuses improve both the damage and durability of her Lancers.
Her Expedition kit is strongly offensive, so the Defense bonus is useful for keeping Lancers active long enough to complete repeated attack cycles.
A meaningful Lancer troop ratio is important because Vengeance and Lethal Precision both depend on Lancer attacks. However, Bertha also supports Marksmen through the Attack buff provided by Vengeance.
How to Unlock Bertha in Whiteout Survival
Bertha becomes available during the Generation 17 hero period. The exact release timing depends on the age and content schedule of the state.
Players can obtain Bertha shards through:
- King of Icefield
- State of Power
- Daily Deals
- Hero Rally
- Mythic General Hero Shards after unlocking her
- Foundry Shop when her shards become available
Bertha is not primarily obtained through the Lucky Wheel. Players planning to build her should prepare competitive event resources, general shards, and any required purchases before her generation arrives.
Preparing Resources for Bertha
Useful resources to prepare include:
- Mythic General Hero Shards
- Hero XP
- Skill Manuals
- Lancer Hero Gear
- Essence Stones
- Exclusive Gear materials
- Adjudicator Widgets
- Resources used during King of Icefield
- Resources used during State of Power
- Hero Rally materials or offers
Unlocking Bertha does not automatically make her stronger than an established Lancer. A fully developed older hero may remain more useful until Bertha reaches a competitive star and skill level.
Choose a realistic star target before committing general shards. This prevents limited resources from being spread across a hero who cannot yet enter the main formation.
Bertha Shard Requirements
Bertha requires an increasing number of shards as she progresses through each full star level.
| Star Progression | Total Shards Required for the Stage |
| First star stage | 10 |
| Second star stage | 40 |
| Third star stage | 115 |
| Fourth star stage | 300 |
| Fifth star stage | 600 |
Each complete star contains six smaller tiers. Every tier must be completed before Bertha advances to the next full star.
A total of 1,065 shards is required to complete all five star stages.
Recommended Bertha Star Targets
| Star Target | Recommendation |
| Unlock only | Suitable for collection and limited testing |
| 2 stars | Usually too weak for an established late-game formation |
| 3 stars | Usable in secondary or transitional formations |
| 4 stars | Strong practical target for regular combat use |
| 5 stars | Maximum Generation 17 performance |
For most players, 4 stars is a practical target if Bertha will become the main Lancer. This provides stronger combat stats and allows her full skill set to compete in advanced formations.
A 5-star Bertha offers maximum performance, but the final star stage requires 600 shards. Players should consider future hero releases before spending all available Mythic General Hero Shards.
Bertha Exploration Skills
Bertha has three Exploration skills. They focus on team healing, Attack buffs, enemy control, and normal-attack damage.
Healing Rain
Bertha sprays a special mist into the air, restoring Health to all friendly heroes. The treatment also provides an adrenaline boost that increases their Attack for three seconds.
| Skill Level | Healing | Friendly Attack Bonus | Duration |
| Level 1 | 200% of Bertha’s Attack | 5% | 3 seconds |
| Level 2 | 220% of Bertha’s Attack | 10% | 3 seconds |
| Level 3 | 240% of Bertha’s Attack | 15% | 3 seconds |
| Level 4 | 260% of Bertha’s Attack | 20% | 3 seconds |
| Level 5 | 280% of Bertha’s Attack | 25% | 3 seconds |
Healing Rain is Bertha’s most important Exploration skill.
At Level 5, every friendly hero recovers Health equal to 280% of Bertha’s Attack. The entire formation also receives 25% additional Attack for three seconds.
This combination gives Healing Rain two important roles:
- It restores Health and extends the battle.
- It creates a temporary offensive window.
The healing becomes stronger as Bertha’s Attack increases. Upgraded Lancer Hero Gear can therefore improve her damage and support value at the same time.
The Attack bonus works best when allied heroes activate powerful skills during its three-second duration.
Healing Rain is particularly useful when:
- Several friendly heroes have lost Health
- The enemy has dealt formation-wide damage
- Allied damage skills are ready to activate
- Bertha has high Attack from Hero Gear
- The formation is built for longer battles
- The team needs both recovery and offensive pressure
Healing Rain restores Health but does not provide a shield or damage reduction. Allies can still be defeated if incoming damage exceeds the amount healed.
Tranquilizer
Bertha throws a needle coated with a numbing substance. The attack damages an enemy and immobilizes it for 1.5 seconds.
| Skill Level | Direct Damage | Immobilization Duration |
| Level 1 | 100% Attack | 1.5 seconds |
| Level 2 | 110% Attack | 1.5 seconds |
| Level 3 | 120% Attack | 1.5 seconds |
| Level 4 | 130% Attack | 1.5 seconds |
| Level 5 | 140% Attack | 1.5 seconds |
Tranquilizer gives Bertha a reliable control effect.
Immobilized enemies cannot change position for 1.5 seconds. This can prevent a target from:
- Moving toward the backline
- Escaping an area-damage effect
- Repositioning around the frontline
- Reaching a vulnerable allied hero
Immobilization is not always identical to Stun. An immobilized enemy may still attack or activate abilities if its target remains within range.
The control duration stays at 1.5 seconds at every skill level. Upgrading Tranquilizer mainly increases its damage.
Tranquilizer works well with:
- Area-damage heroes
- Burning ground effects
- Heroes that attack grouped enemies
- Frontline knockback or control
- Strong single-target Marksmen
- Additional Stun or Freeze effects
Enhancement Reagent
Bertha injects herself with a strengthening reagent, increasing the damage dealt by her normal attacks.
| Skill Level | Normal-Attack Damage Bonus |
| Level 1 | 10% |
| Level 2 | 15% |
| Level 3 | 20% |
| Level 4 | 25% |
| Level 5 | 30% |
At Level 5, Enhancement Reagent increases Bertha’s normal-attack damage by 30%.
This gives her consistent damage between Healing Rain and Tranquilizer activations. The effect becomes more valuable in longer battles where Bertha can complete many normal attacks.
Enhancement Reagent works well with:
- Attack Speed bonuses
- Critical Rate
- Enemy Defense reduction
- Enemy damage-taken increases
- Exclusive gear effects triggered by normal attacks
- Formations that keep Bertha protected
The skill does not increase Healing Rain’s healing percentage. However, improving Bertha’s overall Attack stat through Hero Gear strengthens both healing and normal attacks.
Bertha’s Exploration Role
Bertha works best as a protected support and damage hero positioned behind a durable Infantry frontline.
Healing Rain restores the formation and increases allied Attack. Tranquilizer controls an enemy’s movement, while Enhancement Reagent improves Bertha’s sustained damage.
Bertha works well with:
- A durable Infantry frontline hero
- Heroes with powerful burst skills
- Heroes that benefit from temporary Attack bonuses
- Area-damage Marksmen
- Lancers that can reach enemy backlines
- Heroes that group enemies together
- Shield providers
- Additional control heroes
Healing Rain’s Attack bonus creates an important damage window. Heroes with powerful abilities should ideally activate while the buff is active.
Bertha can serve as the main healer in some formations, but she may need additional protection against teams with heavy burst damage.
Bertha Expedition Skills
Bertha’s Expedition skills focus on Squad Lethality, repeated Lancer attacks, Marksman Attack, and enemy damage amplification.
Dissection
Bertha uses her knowledge of enemy vulnerabilities to increase friendly Squad Lethality.
| Skill Level | Squad Lethality Bonus |
| Level 1 | 5% |
| Level 2 | 10% |
| Level 3 | 15% |
| Level 4 | 20% |
| Level 5 | 25% |
Dissection is Bertha’s most flexible Expedition skill.
At Level 5, the squad receives 25% additional Lethality. This improves the offensive performance of the formation throughout the battle.
The skill does not require:
- A chance-based activation
- A particular enemy troop type
- A specific combat turn
- A temporary trigger
- A low-Health condition
This makes Dissection useful in most Expedition content, including:
- Bear Hunt
- Offensive rallies
- City attacks
- Fortress and stronghold battles
- State of Power
- Sunfire Castle
- Main PvP marches
- Defensive formations
Dissection is especially valuable when combined with additional Attack bonuses. Attack and Lethality improve different parts of troop damage, making them useful together.
Vengeance
Every second Lancer attack receives a large damage bonus. The activation also increases friendly Marksmen’s Attack for one turn.
| Skill Level | Bonus Damage on Every Second Lancer Attack | Marksman Attack Bonus | Duration |
| Level 1 | 25% | 6% | 1 turn |
| Level 2 | 50% | 12% | 1 turn |
| Level 3 | 75% | 18% | 1 turn |
| Level 4 | 100% | 24% | 1 turn |
| Level 5 | 125% | 30% | 1 turn |
Vengeance supports two troop types at the same time.
At Level 5:
- Every second Lancer attack deals 125% additional damage.
- Friendly Marksmen receive 30% additional Attack for one turn.
The repeated Lancer damage makes Vengeance useful in longer battles. A formation that survives for several attack cycles can activate the effect multiple times.
The Marksman Attack bonus also creates useful troop synergy. Lancers trigger the skill, while Marksmen receive a temporary offensive boost.
Vengeance performs best when:
- The formation contains enough Lancers
- The march also uses a meaningful Marksman ratio
- Battles last for multiple attack cycles
- Marksman attacks occur during the buff
- Other Attack or Lethality bonuses are active
Using very few Lancers reduces the frequency and total value of the empowered attacks.
Lethal Precision
Bertha’s Lancers deal additional damage with every attack and inflict Weakness on the target for one turn.
Weakened targets take additional damage from friendly troops.
| Skill Level | Bonus Lancer Damage per Attack | Target Damage Taken Increase | Duration |
| Level 1 | 12% | 5% | 1 turn |
| Level 2 | 24% | 10% | 1 turn |
| Level 3 | 36% | 15% | 1 turn |
| Level 4 | 48% | 20% | 1 turn |
| Level 5 | 60% | 25% | 1 turn |
Lethal Precision is one of Bertha’s strongest offensive Expedition skills.
At Level 5, every Lancer attack deals 60% additional damage. The target also takes 25% more damage for one turn.
The Weakness debuff can increase damage from:
- Infantry
- Lancers
- Marksmen
- Normal troop attacks
- Troop skill effects
- Other damage sources that strike the weakened target
This makes Lethal Precision valuable beyond Bertha’s personal Lancer damage.
The skill performs best when:
- The formation contains a meaningful Lancer ratio
- Strong Marksman attacks follow the Lancer attack
- The march has high Attack and Lethality
- The enemy frontline is durable
- The battle lasts for several turns
Lethal Precision and Vengeance work together naturally. Lethal Precision improves every Lancer attack, while Vengeance adds another large bonus to every second attack.
Bertha’s Expedition Role
Bertha is an offensive Lancer who also supports Marksmen and the wider formation.
Her full Expedition kit provides:
- Squad Lethality
- Additional damage on every Lancer attack
- A larger bonus on every second Lancer attack
- Marksman Attack
- Enemy damage amplification
This makes her suitable for balanced formations containing strong Lancer and Marksman troop groups.
Bertha does not provide a standard Health or Defense bonus through her regular Expedition skills. Pair her with heroes who improve survivability when using her in difficult PvP battles.
Bertha Exclusive Gear: Adjudicator
Bertha’s exclusive hero equipment is Adjudicator. It improves her Exploration stats while adding Expedition Lethality and Health.
| Equipment Detail | Maximum Value |
| Equipment Name | Adjudicator |
| Maximum Equipment Power | 4,497,750 |
| Exploration Attack | 8,995 |
| Exploration Defense | 8,995 |
| Exploration Health | 89,955 |
| Expedition Lethality | 575% |
| Expedition Health | 575% |
Adjudicator provides balanced Exploration Attack and Defense, matching Bertha’s base stat distribution.
The Attack bonus is especially useful because it improves:
- Healing Rain’s Health restoration
- Tranquilizer damage
- Normal attacks
- Enhancement Reagent’s practical value
- Other Attack-based effects
The additional Expedition Lethality improves troop damage, while Expedition Health adds durability to Bertha’s formation.
Serum Vitalis
At the start of battle, Bertha gives all friendly heroes a special serum. The effect increases their Attack Speed and reduces the damage they receive for ten seconds.
| Exclusive Skill Detail | Effect |
| Skill Name | Serum Vitalis |
| Activation | Start of battle |
| Main Bonus | Increases allied Attack Speed |
| Defensive Bonus | Reduces damage received |
| Duration | 10 seconds |
| Exact Maximum Values | TBA |
The exact Attack Speed and damage-reduction percentages are not currently displayed in the available data. These values may be finalized or updated in a future game version.
Even without the exact percentages, Serum Vitalis has a clear role. It improves the formation’s performance during the opening ten seconds of battle.
Additional Attack Speed allows heroes to:
- Complete normal attacks more frequently
- Generate energy or Rage faster when applicable
- Activate normal-attack effects more often
- Apply greater early pressure
- Reach attack-based triggers sooner
The damage-reduction effect helps the formation survive the enemy’s opening attacks.
Serum Vitalis works particularly well with:
- Heroes that depend on normal attacks
- Heroes with attack-count mechanics
- Strong early burst formations
- Fragile damage dealers
- Bertha’s Enhancement Reagent
- Formations that need protection before healing activates
Antibodies
Antibodies increases the Lethality of troops defending a city or other applicable defensive objective.
| Exclusive Skill Detail | Effect |
| Skill Name | Antibodies |
| Main Bonus | Increases Defender Troop Lethality |
| Exact Maximum Value | TBA |
The exact maximum percentage is not currently displayed in the available data.
Antibodies gives Bertha a specialized role in defensive PvP. It can improve troop damage when defending:
- Cities
- Facilities
- Fortresses
- Strongholds
- Alliance structures
- Sunfire Castle
- State of Power objectives
The skill combines well with Bertha’s regular Expedition abilities:
- Dissection increases Squad Lethality.
- Vengeance empowers Lancer attacks and buffs Marksmen.
- Lethal Precision makes targets take more damage.
- Antibodies adds Defender Troop Lethality.
This allows Bertha to support an aggressive defensive formation that attempts to defeat attackers through high damage.
Is Adjudicator Worth Upgrading?
Adjudicator is worth upgrading when Bertha is part of the main Exploration, Arena, rally, Bear Hunt, or city-defense formation.
| Bertha Usage | Equipment Recommendation |
| Collection or secondary hero | Low investment |
| Regular Exploration or Arena hero | Moderate investment |
| Main Lancer hero | High investment |
| City-defense specialist | Prioritize Antibodies |
| Exploration support build | Prioritize Serum Vitalis |
Exclusive Gear materials are limited. Heavy investment should normally wait until Bertha has enough stars and skill development to remain in the main formation.
Serum Vitalis provides broad value in Exploration and Arena. Antibodies becomes more important for players who regularly defend cities or alliance objectives.
Best Uses for Bertha
Bertha can contribute in several Whiteout Survival game modes. Her strongest roles involve formation healing, Lancer damage, Squad Lethality, Marksman support, and enemy damage amplification.
Exploration
Bertha is a strong Exploration support hero.
Healing Rain restores Health to all friendly heroes and provides a temporary Attack bonus. Tranquilizer controls an enemy’s movement, while Enhancement Reagent increases Bertha’s normal-attack damage.
She performs best when:
- Several allies can benefit from the healing
- Strong hero skills activate during the Attack bonus
- A durable Infantry hero protects her
- Battles last long enough for repeated Healing Rain activations
- Bertha has high Attack from Lancer Hero Gear
- Attack Speed improves her sustained damage
Bertha may not replace a dedicated tank or shield provider. Her role is to restore lost Health and improve offensive pressure.
Arena
Arena is one of Bertha’s strongest Exploration uses.
Formation-wide healing can help recover from enemy area attacks. The 25% Attack bonus from Healing Rain also creates a strong burst window for allied damage dealers.
Tranquilizer can prevent an enemy from repositioning, while Serum Vitalis can provide Attack Speed and damage reduction during the opening part of the fight.
A practical Bertha Arena formation should include:
- A durable Infantry frontline hero
- A second frontline or control hero
- Bertha in a protected position
- A strong Marksman damage dealer
- Another burst or area-damage hero
Bertha works particularly well with heroes that have powerful abilities but need enough time to activate them.
Bear Hunt
Bertha can be a strong Bear Hunt hero because all three of her Expedition skills improve damage.
Dissection increases Squad Lethality. Vengeance empowers every second Lancer attack and increases Marksman Attack. Lethal Precision adds damage to every Lancer attack and makes the target take more damage.
Her Bear Hunt value is strongest when:
- She has high Expedition skill levels
- The formation contains enough Lancers
- The rally also uses a strong Marksman ratio
- Lethal Precision is active in the correct hero position
- The rally contains other Attack and Lethality bonuses
- Her exclusive gear has been developed
Battle reports should still be compared because the best Bear Hunt formation can depend on hero positions, skill activation rules, troop ratios, and the rally leader’s bonuses.
Offensive Rallies
Bertha is well suited to offensive rallies.
Her Expedition kit provides several offensive effects:
- 25% Squad Lethality
- Bonus damage on every Lancer attack
- 125% additional damage on every second Lancer attack
- Up to 30% Marksman Attack
- Up to 25% increased damage taken by the target
These bonuses allow Bertha to support both her Lancers and the rest of the formation.
She can contribute to:
- City attack rallies
- Fortress battles
- Stronghold battles
- State of Power
- Sunfire Castle
- Alliance combat events
Bertha does not provide a directly named Rally Attack or Rally Lethality bonus through her standard kit. However, her combination of Squad Lethality and enemy Weakness can still provide strong rally value.
City Defense
Bertha can be useful in city-defense formations, especially after upgrading Antibodies.
Dissection increases Lethality, while Vengeance and Lethal Precision improve Lancer and Marksman damage. Antibodies provides another Lethality bonus for defending troops.
This creates an aggressive defensive setup with:
- Squad Lethality
- Defender Troop Lethality
- Increased Lancer damage
- Marksman Attack
- Enemy damage amplification
- Expedition Health from Adjudicator
Bertha does not provide Defender Health or Defender Defense through her listed skills. Pair her with heroes that strengthen troop durability.
Garrison Defense
Bertha can also contribute to garrison formations.
Long battles give Lancers more opportunities to activate Vengeance and repeatedly apply Weakness through Lethal Precision.
She works well with defensive heroes that provide:
- All-troop Health
- Defender Health
- Defender Defense
- Infantry damage reduction
- Enemy Attack reduction
- Enemy Lethality reduction
The exact value of Antibodies may depend on whether the selected structure battle classifies Bertha’s formation as defending troops.
State of Power and Large-Scale PvP
Bertha can be useful during State of Power, Sunfire Castle, and other large alliance battles.
She can contribute to:
- Offensive rallies
- Defensive formations
- City attacks
- City defense
- Structure battles
- Main PvP marches
- Reinforcement formations
- Long field engagements
Her Squad Lethality and Weakness debuff remain useful in most matchups. She becomes especially valuable when the formation contains strong Lancer and Marksman troop groups.
Bertha Skill Upgrade Priority
Bertha’s skill priority depends on whether she is mainly used for Exploration, Arena, Bear Hunt, rallies, or defensive PvP.
Exploration Skill Priority
| Priority | Skill | Reason |
| 1 | Healing Rain | Restores all allies and increases their Attack |
| 2 | Enhancement Reagent | Improves sustained normal-attack damage |
| 3 | Tranquilizer | Provides damage and immobilization |
Healing Rain should normally receive the highest priority. Upgrading it increases both its healing and allied Attack bonus.
At Level 5, it restores 280% of Bertha’s Attack and increases friendly Attack by 25%.
Enhancement Reagent is the next priority for sustained damage. It becomes especially useful when Bertha receives Attack Speed from Serum Vitalis or another allied effect.
Tranquilizer remains useful for control, but its immobilization duration does not increase with skill level.
For control-focused Arena formations, players can upgrade Tranquilizer alongside Healing Rain.
Expedition Skill Priority
| Priority | Skill | Reason |
| 1 | Lethal Precision | Improves every Lancer attack and increases target damage taken |
| 2 | Dissection | Reliably increases Squad Lethality |
| 3 | Vengeance | Empowers every second Lancer attack and buffs Marksmen |
Lethal Precision should normally receive the highest priority. It improves every Lancer attack and provides a Weakness debuff that benefits the full formation.
Dissection is the most reliable general bonus because it increases Squad Lethality throughout the battle.
Vengeance remains very strong, especially in balanced Lancer and Marksman formations. However, its larger Lancer bonus only activates on every second attack.
For Marksman-heavy formations, players may prioritize:
- Lethal Precision
- Vengeance
- Dissection
For general rallies and Bear Hunt, Dissection and Lethal Precision should receive the highest priority.
Best Formation Strategy for Bertha
Bertha performs best in a balanced formation that protects her and contains enough Lancers to activate her Expedition effects consistently.
A practical Exploration or Arena formation can include:
- A durable Infantry hero in the frontline
- A second frontline or control hero
- Bertha in a protected position
- A powerful Marksman
- Another high-damage or support hero
Useful Exploration effects to combine with Bertha include:
- Shields
- Damage reduction
- Area damage
- Strong burst skills
- Attack Speed
- Enemy Defense reduction
- Enemy grouping
- Additional control
Healing Rain’s Attack bonus should be combined with strong allied damage abilities whenever possible.
For Expedition, Bertha benefits from a meaningful Lancer ratio. Both Vengeance and Lethal Precision depend on Lancer attacks.
Marksmen are also important because Vengeance can increase their Attack by up to 30%.
Useful Expedition bonuses to combine with Bertha include:
- Lancer Attack
- Lancer Lethality
- Marksman Attack
- Marksman Lethality
- All-troop Attack
- Squad Lethality
- Enemy damage-taken increases
- Infantry Health and Defense
- Formation-wide damage reduction
Bertha already provides substantial offensive support. Pair her with heroes that improve troop Health, Defense, or incoming damage reduction.
Is Bertha Worth Investing In?
Bertha is worth considering for players who need a Generation 17 Lancer focused on healing, offensive troop bonuses, Lancer damage, and enemy Weakness.
Her value is highest for players who regularly participate in Arena, Bear Hunt, offensive rallies, and large-scale PvP.
Reasons to Invest in Bertha
- Heals all friendly Exploration heroes
- Increases allied Attack after healing
- Immobilizes enemy targets
- Increases her normal-attack damage
- Has balanced Exploration stats
- Increases Squad Lethality
- Empowers every second Lancer attack
- Increases Marksman Attack
- Adds damage to every Lancer attack
- Makes enemies take additional damage
- Exclusive gear improves Attack, Defense, and Health
- Can provide opening Attack Speed and damage reduction
- Can increase Defender Troop Lethality
- Useful in Arena, Bear Hunt, rallies, defense, and PvP
Reasons to Limit Investment
- Not primarily available through the Lucky Wheel
- Requires substantial shard or event investment
- Provides no personal shield
- Healing Rain does not reduce incoming damage
- Tranquilizer immobilizes rather than fully stunning the target
- Enhancement Reagent only improves normal attacks
- Two Expedition skills depend on Lancer attacks
- Vengeance only empowers every second Lancer attack
- A low Lancer ratio reduces her Expedition value
- Exact exclusive skill percentages are not currently displayed
- Exclusive Gear requires rare materials
- A low-star Bertha may not replace a developed older Lancer
- Future generations may eventually provide higher stats
Bertha can be a strong long-term investment for players who need both support and offensive value from their Lancer slot.
Players focused entirely on maximum defense may prefer a hero with direct Health, Defense, or damage-reduction bonuses. Players focused on mixed Lancer and Marksman damage can receive more value from Bertha’s complete kit.
Bertha Upgrade Priority
A practical Bertha investment order is:
- Check which Bertha shard events are available in your state.
- Unlock Bertha and choose a realistic star target.
- Raise her to at least 3 stars before expecting strong late-game results.
- Aim for 4 stars if she will become your primary Lancer.
- Upgrade Healing Rain for formation healing and Attack.
- Upgrade Enhancement Reagent for sustained Exploration damage.
- Upgrade Tranquilizer for direct damage and control.
- Upgrade Lethal Precision for Lancer damage and Weakness.
- Upgrade Dissection for Squad Lethality.
- Improve Vengeance for repeated Lancer damage and Marksman Attack.
- Equip Bertha with upgraded Lancer Hero Gear.
- Invest in Adjudicator after confirming her long-term role.
- Prioritize Serum Vitalis for Exploration and Arena.
- Prioritize Antibodies for city and structure defense.
- Continue toward 5 stars only when the cost fits your future hero plan.
Do not judge Bertha only by her displayed Hero Power. Her performance also depends on skill levels, Hero Gear, exclusive equipment, troop ratios, formation placement, and supporting heroes.
Mistakes to Avoid When Upgrading Bertha
Unlocking Bertha Without a Star Target
A newly unlocked Bertha may be weaker than a developed older Lancer. Decide whether you can reach at least 3 or 4 stars before committing major resources.
Spending General Shards Without Planning Ahead
Mythic General Hero Shards can be used on many Legendary heroes. Avoid using all of them unless Bertha will remain in your main formation.
Ignoring Bertha’s Attack Stat
Healing Rain scales with Bertha’s Attack. Increasing Attack improves both her healing and damage.
Treating Healing Rain as a Shield
Healing Rain restores lost Health but does not absorb future damage. Heroes can still be defeated by heavy burst attacks.
Wasting the Attack-Bonus Window
Healing Rain increases allied Attack for three seconds. Strong hero abilities should activate during this window whenever possible.
Treating Tranquilizer as a Full Stun
Tranquilizer immobilizes the target. It prevents movement but may not stop attacks or abilities when the target remains within range.
Placing Bertha on the Frontline
Bertha has balanced defensive stats, but she is still a Lancer. A dedicated Infantry hero should normally protect her.
Using Too Few Lancers
Vengeance and Lethal Precision depend on Lancer attacks. A very low Lancer troop ratio reduces Bertha’s Expedition value.
Ignoring Marksman Synergy
Vengeance can increase Marksman Attack by up to 30%. Bertha performs well in formations with strong Marksman troops.
Expecting Vengeance on Every Attack
The larger damage bonus activates on every second Lancer attack, not every attack.
Ignoring the Weakness Debuff
Lethal Precision makes the target take additional damage for one turn. Strong allied attacks should occur while Weakness is active.
Building a Formation With Only Offensive Bonuses
Bertha already provides substantial Lethality and damage support. Pairing her only with offensive heroes may leave the formation without enough durability.
Assuming Exclusive Skill Values Are Final
The exact Serum Vitalis and Antibodies percentages are not currently displayed. Check the in-game values before making a major exclusive gear investment.
Upgrading Adjudicator Too Early
Exclusive Gear materials are limited. Heavy investment may not be efficient while Bertha is at a low star level or used only in a secondary formation.
Replacing a Developed Lancer Too Quickly
A Generation 17 hero is not automatically stronger when underdeveloped. Compare battle reports before transferring your best Lancer Hero Gear to Bertha.
