Whiteout Survival Bertha Guide: Skills, Stats, Exclusive Gear, and Best Use

Bertha is a Generation 17 Legendary Lancer in Whiteout Survival who combines formation-wide healing with aggressive Expedition support. In Exploration, she heals every friendly hero, increases their Attack, immobilizes an enemy, and improves her own normal attacks. In Expedition, she adds Squad Lethality, strengthens repeated Lancer attacks, boosts Marksmen, and makes enemies take more damage.

That combination makes Bertha more than a standard damage-focused Lancer. She can fit Arena and Exploration teams that need recovery while also providing a highly offensive Expedition kit for rallies and PvP. Her main limitation is that two Expedition skills depend heavily on Lancer attacks, so formation composition matters.

Bertha Overview

Detail	Bertha Information
Rarity	Legendary
Class	Lancer
Subclass	Combat
Hero Generation	Generation 17
Approximate State Timing	Around state day 1240; exact timing can vary
Main Role	Healing, Lancer damage, Marksman support, and enemy vulnerability
Strong Uses	Exploration, Arena, rallies, PvP, and aggressive defensive formations
Exclusive Gear	Adjudicator
Main Strengths	Team healing, Attack buffs, Squad Lethality, Lancer damage, and Weakness
Main Limitation	Several Expedition effects need meaningful Lancer participation

Generation 17 includes Aiden as Infantry, Bertha as Lancer, and Eleanor as Marksman. Current progression references place the generation at roughly state day 1240, although exact release timing can differ between states.

Bertha’s defining feature is that her Exploration and Expedition roles are quite different. Exploration makes her a healer and support hero, while Expedition turns her into an aggressive Lancer enabler.

Is Bertha Good in Whiteout Survival?

Yes. Bertha is a strong Gen 17 Lancer, particularly for players who want both Exploration healing and an offensive Expedition hero.

Her Exploration value comes primarily from Healing Rain. At maximum level, it restores every friendly hero for 280% of Bertha’s Attack and then increases their Attack by 25% for three seconds.

Her Expedition kit is even more damage-oriented:

• Dissection provides up to 25% Squad Lethality.
• Vengeance strengthens every second Lancer attack by up to 125% and gives Marksmen 30% Attack for one turn.
• Lethal Precision adds up to 60% damage to every Lancer attack.
• Lethal Precision also makes the target take up to 25% more damage for one turn.

Bertha is therefore strongest when a formation contains enough Lancers to activate her attack-based effects consistently while also having strong Marksmen that can capitalize on Vengeance and Weakness.

She is less attractive for players who want a pure defensive Lancer or who cannot develop her beyond a low star level.

How to Get Bertha in Whiteout Survival

Bertha’s current shard sources are:

• King of Icefield
• State of Power
• Daily Deals
• Hero Rally
• Mythic General Hero Shards
• Foundry Shop

Bertha is not the Gen 17 Lucky Wheel hero. Players who want to make her their primary Lancer should therefore plan around competitive event rewards, later shard sources, and Mythic General Hero Shards rather than expecting a predictable Gem-based wheel progression.

Resources to Prepare for Bertha

• Mythic General Hero Shards
• Hero XP
• Mythic Exploration and Expedition skill materials
• Lancer Hero Gear
• Essence Stones and other Hero Gear materials
• Adjudicator Widgets
• Exclusive Gear upgrade materials
• Resources for King of Icefield and State of Power progression

Bertha Shard Requirements

Bertha uses the standard Legendary five-star promotion structure, with six smaller tiers inside every full star.

Star Stage	Shards for That Stage	Cumulative Promotion Shards
1 Star	10	10
2 Stars	40	50
3 Stars	115	165
4 Stars	300	465
5 Stars	600	1,065

The five listed star-promotion stages total 1,065 shards. The final jump from four to five stars alone requires 600, so maximum development is a major commitment.

Recommended Bertha Star Targets

Star Target	Recommendation
Unlock	Collection and limited testing
2 Stars	Usually too weak for an established Gen 17 main formation
3 Stars	Possible transitional or secondary use
4 Stars	Practical target for serious regular combat use
5 Stars	Maximum development for committed Bertha users

Four stars is a sensible target when Bertha is intended to become your primary Lancer. Five stars makes more sense for players who expect her to remain important in Arena, rallies, or competitive PvP.

Bertha Stats

Exploration Stats

Stat	Maximum Value
Attack	44,376
Defense	44,376
Health	443,778

Bertha has equal listed Attack and Defense with a large Health pool. Attack is particularly important because Healing Rain calculates its healing from Bertha’s Attack.

Improving Attack therefore benefits:

• Healing Rain’s healing
• Tranquilizer damage
• Normal attacks
• Enhancement Reagent’s total contribution

Her defensive stats help her survive AoE pressure, but she should normally remain behind a dedicated Infantry frontline rather than serving as the primary tank.

Expedition Stats

Stat	Maximum Value
Lancer Attack	2,301.84%
Lancer Defense	2,301.84%

Bertha’s base Expedition bonuses specifically improve Lancers, matching a skill kit in which Vengeance and Lethal Precision both depend on Lancer attacks.

Her wider formation support comes from Dissection’s Squad Lethality, Vengeance’s Marksman Attack bonus, and Lethal Precision’s Weakness debuff.

Bertha Exploration Skills

Healing Rain

Healing Rain restores Health to all friendly heroes and then temporarily increases their Attack.

Skill Level	Healing	Friendly Attack Increase	Duration
1	200% of Bertha’s Attack	5%	3 seconds
2	220% of Bertha’s Attack	10%	3 seconds
3	240% of Bertha’s Attack	15%	3 seconds
4	260% of Bertha’s Attack	20%	3 seconds
5	280% of Bertha’s Attack	25%	3 seconds

At Level 5, every friendly hero receives healing equal to 280% of Bertha’s Attack and gains 25% Attack for three seconds.

This makes Healing Rain both a recovery skill and a burst-damage setup tool. Strong allied abilities provide more value when they land during the three-second Attack window.

The healing scales from Bertha’s Attack, making offensive Hero Gear valuable even when Bertha is primarily being used as a support hero.

Healing Rain restores lost Health; it is not a shield and does not prevent the next incoming attack.

Tranquilizer

Tranquilizer damages one enemy and immobilizes it for 1.5 seconds.

Skill Level	Direct Damage	Immobilization
1	100% of Bertha’s Attack	1.5 seconds
2	110% of Bertha’s Attack	1.5 seconds
3	120% of Bertha’s Attack	1.5 seconds
4	130% of Bertha’s Attack	1.5 seconds
5	140% of Bertha’s Attack	1.5 seconds

The control duration does not increase with skill level; upgrading Tranquilizer raises its damage.

Immobilization is useful for restricting enemy movement and keeping targets within favorable areas of the battlefield. It is listed as an immobilize rather than a Stun, so it should not be treated as identical to every other control effect.

Enhancement Reagent

Enhancement Reagent increases Bertha’s normal-attack damage.

Skill Level	Normal-Attack Damage Increase
1	10%
2	15%
3	20%
4	25%
5	30%

At Level 5, Bertha’s normal attacks deal 30% more damage. This provides steady offensive value between Healing Rain and Tranquilizer activations.

The skill becomes particularly useful with Attack Speed effects, including Serum Vitalis from Adjudicator.

Bertha’s Exploration Role

Bertha works best as a protected backline or secondary-position support hero rather than a frontline tank.

Her Exploration rhythm looks like this:

1. Healing Rain restores the full formation.
2. The same skill creates a three-second Attack window.
3. Allied burst heroes capitalize on that temporary buff.
4. Tranquilizer restricts enemy movement.
5. Enhancement Reagent gives Bertha sustained damage between active skills.

Useful teammates include a durable Infantry tank, strong burst heroes, AoE damage dealers, shield providers, and additional control heroes.

Bertha Expedition Skills

Dissection

Dissection increases friendly Squad Lethality.

Skill Level	Squad Lethality Increase
1	5%
2	10%
3	15%
4	20%
5	25%

At Level 5, Dissection provides 25% Squad Lethality without requiring an attack counter, chance-based activation, or specific enemy troop type.

That reliability makes it Bertha’s most universally useful Expedition skill.

Dissection is also her first Expedition skill. When Bertha is used as the Hero Captain of a joining rally, this is the skill that can enter the rally-member buff pool.

Vengeance

Vengeance empowers every second Lancer attack and gives friendly Marksmen additional Attack for one turn.

Skill Level	Extra Damage on Every 2nd Lancer Attack	Marksman Attack Increase	Duration
1	25%	6%	1 turn
2	50%	12%	1 turn
3	75%	18%	1 turn
4	100%	24%	1 turn
5	125%	30%	1 turn

At Level 5, every second Lancer attack gains 125% additional damage and Marksmen receive 30% Attack for one turn.

Vengeance therefore rewards two troop groups simultaneously. Lancers trigger the offensive effect, while Marksmen benefit from the resulting Attack buff.

A very low Lancer ratio reduces how much value the formation receives from the Lancer side of this skill.

Lethal Precision

Lethal Precision increases the damage of every Lancer attack and inflicts Weakness on the target for one turn. Weakened targets take additional damage.

Skill Level	Bonus Lancer Damage per Attack	Target Damage Taken Increase	Duration
1	12%	5%	1 turn
2	24%	10%	1 turn
3	36%	15%	1 turn
4	48%	20%	1 turn
5	60%	25%	1 turn

At Level 5, every Lancer attack receives 60% bonus damage and applies Weakness, causing the target to take 25% additional damage for one turn.

The Weakness effect is what makes Lethal Precision valuable beyond Lancers. Other friendly troops can benefit while the affected target is taking increased damage.

Lethal Precision also combines naturally with Vengeance: every Lancer attack gains the first bonus, while every second attack receives the additional Vengeance effect.

How Bertha’s Expedition Skills Work Together

• Dissection: reliable Squad Lethality for the formation.
• Vengeance: stronger repeated Lancer attacks plus Marksman Attack.
• Lethal Precision: extra damage on every Lancer attack plus enemy Weakness.

This makes Bertha an offensive support hero rather than a defensive Lancer. If your formation lacks durability, the other heroes need to compensate with Health, Defense, or damage-reduction effects.

Bertha Exclusive Gear: Adjudicator

Bertha’s exclusive equipment is Adjudicator. The current official hero data lists these maximum values:

Equipment Detail	Maximum Value
Equipment Power	4,497,750
Exploration Attack	8,995
Exploration Defense	8,995
Exploration Health	89,955
Expedition Lethality	575%
Expedition Health	575%

The Attack increase is particularly valuable because Healing Rain scales directly from Bertha’s Attack. Adjudicator therefore improves both Bertha’s offensive output and her healing.

Serum Vitalis

At the start of battle, Serum Vitalis increases the Attack Speed of all friendly heroes and reduces the damage they take for ten seconds.

Skill Level	Attack Speed Increase	Damage Taken Reduction	Duration
1	7%	7%	10 seconds
2	9%	9%	10 seconds
3	11%	11%	10 seconds
4	13%	13%	10 seconds
5	15%	15%	10 seconds

At Level 5, the full hero formation receives 15% Attack Speed and 15% damage reduction for the opening ten seconds.

This fixes one of Bertha’s natural weaknesses in Exploration: Healing Rain restores lost Health, but it does not prevent early burst damage. Serum Vitalis gives the formation protection while also increasing its early offensive pressure.

It also has direct synergy with Enhancement Reagent because faster normal attacks allow Bertha to make greater use of her 30% normal-attack damage bonus.

Antibodies

Antibodies increases the Lethality of Defender Troops.

Skill Level	Defender Troop Lethality Increase
1	5%
2	7.5%
3	10%
4	12.5%
5	15%

At Level 5, defending troops gain 15% Lethality. This gives Bertha a specialized role in aggressive defensive formations where the objective is not merely to survive but also to punish attackers.

Because the wording specifically refers to Defender Troops, Antibodies should not be treated as a universal offensive rally bonus.

Is Adjudicator Worth Upgrading?

Bertha Role	Investment Approach
Collection or secondary hero	Keep investment limited
Main Exploration/Arena Lancer	Moderate-to-high investment can be worthwhile
Main Gen 17 Lancer	High investment is easier to justify
Defensive PvP role	Antibodies significantly increases value
Mainly a rally member	Do not upgrade heavily solely for Antibodies

Exclusive Gear materials are scarce, so Adjudicator should generally follow Bertha’s star and skill development rather than come before it.

Best Uses for Bertha

Mode	Bertha Fit	Why
Exploration	Strong	Full-team healing, Attack buff, control, and sustained damage
Arena	Strong	Healing plus opening protection and team Attack support
Offensive Rally Captain	Strong potential	Squad Lethality, Lancer damage, Marksman Attack, and Weakness
Rally Member	Useful	Dissection can contribute as her first Expedition skill
Bear Hunt	Promising but not yet officially ranked for Gen 17	All three Expedition skills are offensive, but no current validated Gen 17 lineup is published
City/Garrison Defense	Strong offensive support	Antibodies adds Defender Troop Lethality
Large-Scale PvP	Strong	Damage amplification and Lancer/Marksman synergy

Exploration

Bertha is an unusual Exploration Lancer because much of her value comes from supporting the other four heroes.

Healing Rain can recover damage across the entire formation instead of helping only one target. The follow-up Attack buff then gives the same team an opportunity to turn defense into offense.

Protect Bertha behind a durable frontline so she has enough time to use Healing Rain repeatedly.

Arena

Arena is one of Bertha’s strongest Exploration modes. Formation-wide damage is common, which increases the usefulness of a heal that affects every hero.

Serum Vitalis also improves the opening ten seconds by combining Attack Speed with damage reduction. Once Healing Rain activates, the formation receives another offensive window through its Attack bonus.

A practical Arena team can contain:

• A durable Infantry tank
• A second frontline or control hero
• Bertha in a protected position
• A strong Marksman or burst hero
• An additional damage or support hero

Bertha already supplies healing, so the remaining slots can often lean more heavily toward damage or control than a formation without recovery.

Offensive Rallies

Bertha’s regular Expedition kit is naturally aggressive enough for offensive rally-captain use.

Dissection gives the squad up to 25% Lethality. Lethal Precision adds damage to every Lancer attack and increases damage taken by the target, while Vengeance adds another large bonus every second Lancer attack and strengthens Marksmen.

The exact value depends on troop composition. A formation with almost no Lancers wastes much of Bertha’s potential.

Antibodies should not be included when evaluating an attacking rally because it specifically applies to Defender Troops.

Joining Rallies

Bertha can be useful as the Hero Captain of a joining march because Dissection is her first Expedition skill.

At Level 5, that skill provides 25% Squad Lethality. However, only four joining-member first skills are selected, with skill level affecting which ones enter the rally.

Follow your alliance’s rally instructions instead of assuming Bertha should always occupy the first slot.

Bear Hunt

Bertha’s Expedition kit contains several effects that are theoretically attractive for Bear Hunt damage:

• 25% Squad Lethality from Dissection
• Bonus damage on Lancer attacks
• Up to 125% extra damage on every second Lancer attack
• Up to 30% Marksman Attack
• Up to 25% increased damage taken from Weakness

However, the current published Bear Hunt guide does not yet provide a tested Gen 17 hero ranking. For that reason, Bertha should not be labeled the definitive best Gen 17 Bear Lancer without validated battle-report data.

If using Bertha as a rally captain, test different Lancer/Marksman ratios and compare actual Bear Hunt reports against your established lineup.

If joining another player’s Bear rally, only Dissection is relevant as Bertha’s potential rally-member skill. Vengeance and Lethal Precision do not automatically transfer from a joining march.

City and Garrison Defense

Bertha’s regular Expedition kit is offensive rather than defensive, but Antibodies gives her a specific defender role by adding up to 15% Defender Troop Lethality.

This suits aggressive garrisons that already receive Health, Defense, or damage reduction from their other heroes.

Bertha pairs well with defensive heroes that provide:

• All-troop Health
• Defender Health
• Defender Defense
• Infantry protection
• Enemy Attack reduction
• Enemy Lethality reduction

Those effects compensate for the lack of regular defensive Expedition skills in Bertha’s own kit.

Large-Scale PvP

Bertha is well suited to PvP where both Lancers and Marksmen make meaningful contributions. Weakness helps the formation focus targets, Dissection improves general offensive pressure, and Vengeance connects Lancer attacks to Marksman performance.

Her best role depends on the rest of the three-hero Expedition squad and whether the formation is attacking or defending.

Bertha Skill Upgrade Priority

Exploration and Arena Priority

Priority	Skill	Reason
1	Healing Rain	Improves both full-team healing and the Attack bonus
2	Enhancement Reagent	Provides consistent normal-attack damage and synergizes with Serum Vitalis
3	Tranquilizer	Provides control, but its 1.5-second immobilization does not scale with level

Healing Rain is the clear first priority for Bertha’s Exploration identity.

Enhancement Reagent is generally the better second investment for sustained performance, while Tranquilizer can move higher if movement control is especially valuable to your Arena lineup.

Expedition Priority

Priority	Skill	Reason
1	Dissection	Reliable Squad Lethality and Bertha’s rally-member skill
2	Lethal Precision	Improves every Lancer attack and applies Weakness
3	Vengeance	Large recurring Lancer bonus plus Marksman Attack

Dissection is the safest general priority because its effect is unconditional and also matters when Bertha joins rallies as the Hero Captain.

For a dedicated rally-captain build with a strong Lancer component, Lethal Precision can be upgraded just as aggressively because its damage-taken debuff helps the rest of the formation.

Best Formation Strategy for Bertha

Exploration and Arena

Bertha should normally be protected by a durable frontline rather than absorbing the first wave of attacks herself.

Useful teammate effects include:

• Strong Infantry tanking
• Shields and damage reduction
• High burst damage
• AoE attacks
• Enemy Defense reduction
• Attack Speed
• Enemy grouping
• Additional control

The team should be capable of exploiting Healing Rain’s three-second Attack bonus rather than treating the skill as healing alone.

Expedition Formations

Bertha needs meaningful Lancer participation because Vengeance and Lethal Precision activate from Lancer attacks.

Marksmen also have direct synergy because Vengeance can raise their Attack by 30%.

Useful complementary bonuses include:

• Lancer Attack and Lethality
• Marksman Attack and Lethality
• Squad Attack or Lethality
• Enemy damage-taken increases
• Enemy Defense reduction
• Infantry Health and Defense
• Formation-wide damage reduction

There is no single universal troop ratio for Bertha. The correct composition depends on the other two heroes, troop stats, opponent, and battle objective.

Is Bertha Worth Investing In?

Bertha is worth investing in if you need a Gen 17 Lancer that can heal in Arena and Exploration while providing aggressive Lancer and Marksman support in Expedition.

For F2P and Low-Spend Players

Bertha is harder to build predictably than Gen 17’s Lucky Wheel hero because her primary acquisition methods include competitive events and other limited shard sources.

F2P players should be especially careful about spending Mythic General Hero Shards unless Bertha can reach a competitive star level and clearly improve the main formation.

For Rally Leaders

Bertha has a strong offensive Expedition kit for rally-captain use. Dissection, Vengeance, and Lethal Precision all contribute to damage when the rally contains an appropriate Lancer and Marksman mix.

For Rally Members

Her value is much simpler: Dissection is the only regular Expedition skill that can enter the joining-member buff pool because it is her first skill.

For Defensive Players

Adjudicator gives Bertha a dedicated defender bonus through Antibodies, but her normal Expedition kit still emphasizes damage. Pair her with more defensive heroes if troop survival is the main concern.

If you are comparing completely different progression paths rather than developing a Gen 17 roster hero by hero, viewing a wos account for sale is an optional alternative. Compare state age, hero generations, stars, Hero Gear, exclusive equipment, research, and account progression instead of total Power alone.

Reasons to Invest in Bertha

• Full-team Exploration healing
• Up to 25% temporary Attack for all friendly heroes
• Immobilization control
• 30% normal-attack damage increase
• 25% Squad Lethality
• 60% bonus damage on every Lancer attack
• 125% extra damage on every second Lancer attack
• 30% Marksman Attack from Vengeance
• 25% target damage-taken increase from Weakness
• Serum Vitalis adds 15% Attack Speed and 15% damage reduction for 10 seconds
• Antibodies adds 15% Defender Troop Lethality
• Strong synergy between Lancers and Marksmen

Reasons to Limit Investment

• Not the Generation 17 Lucky Wheel hero
• High stars require significant shard investment
• No personal shield or Exploration damage-reduction skill in her base kit
• Healing Rain cannot prevent lethal burst before healing occurs
• Tranquilizer’s control duration remains 1.5 seconds
• Enhancement Reagent affects normal attacks only
• Two Expedition skills depend on Lancer attacks
• Vengeance only applies its large Lancer bonus every second attack
• A very low Lancer ratio wastes much of the kit
• Antibodies is defender-specific
• Exclusive Gear requires scarce materials
• No validated Gen 17 Bear Hunt ranking is currently published
• An underdeveloped Bertha may not replace a highly developed older Lancer

Bertha Upgrade Priority

1. Confirm that Gen 17 is approaching or active on your state.
2. Review which Bertha shard sources are realistically available.
3. Choose a star target before spending Mythic General Hero Shards.
4. Aim for around four stars if Bertha will become your serious main Lancer and resources allow it.
5. Upgrade Healing Rain for healing and team Attack.
6. Develop Enhancement Reagent for sustained Exploration damage.
7. Upgrade Tranquilizer when additional control is useful.
8. Max Dissection for reliable Squad Lethality.
9. Upgrade Lethal Precision for Lancer damage and Weakness.
10. Develop Vengeance for repeated Lancer damage and Marksman Attack.
11. Equip Bertha with developed Lancer Hero Gear.
12. Invest in Adjudicator once her long-term role is confirmed.
13. Prioritize Serum Vitalis for Exploration and Arena.
14. Develop Antibodies when city or structure defense is important.
15. Only commit to five stars when the final shard cost fits your future hero plan.

Mistakes to Avoid With Bertha

Unlocking Bertha Without a Star Plan

A low-star Bertha can remain weaker than an older, fully developed Lancer. Decide how far you can realistically promote her before spending limited resources.

Ignoring Bertha’s Attack Stat

Healing Rain scales from Bertha’s Attack. Improving Attack increases both her damage and her healing output.

Treating Healing Rain Like a Shield

Healing Rain restores lost Health. It does not absorb incoming damage or guarantee that a low-Health hero survives the next burst.

Wasting Healing Rain’s Attack Window

The allied Attack increase lasts three seconds. Strong hero skills provide more value when they activate during that period.

Putting Bertha on the Frontline

Bertha has strong Gen 17 stats, but she remains a Lancer. A dedicated Infantry tank should normally absorb the heaviest Exploration and Arena pressure.

Treating Tranquilizer as a Stun

The skill description specifically says immobilize. Treat it as movement control rather than assuming it behaves exactly like a Stun.

Using Too Few Lancers

Both Vengeance and Lethal Precision depend on Lancer attacks. A very small Lancer component sacrifices much of Bertha’s Expedition value.

Ignoring Marksman Synergy

Vengeance gives Marksmen up to 30% Attack for one turn. Strong Marksmen are an important part of Bertha’s Expedition synergy.

Expecting Vengeance on Every Lancer Attack

The large Vengeance damage bonus applies to every second Lancer attack. Lethal Precision is the skill that adds bonus damage to every Lancer attack.

Ignoring Weakness

Lethal Precision can make the target take 25% more damage for one turn. The rest of the formation should capitalize on that window.

Assuming All Bertha Skills Work When Joining a Rally

Only Dissection can enter the rally-member buff pool when Bertha is the Hero Captain of a joining march. Her remaining Expedition skills do not automatically transfer.

Assuming Antibodies Is a Rally-Offense Bonus

Antibodies specifically increases Defender Troop Lethality. Do not count it as a universal attacking-rally bonus.

Calling Bertha the Best Gen 17 Bear Hero Without Testing

Her Expedition kit looks strong for damage, but the current published Bear Hunt guide does not yet validate a Gen 17 ranking. Compare battle reports before replacing a proven lineup.

Upgrading Adjudicator Too Early

Exclusive Gear materials are limited. Heavy investment makes more sense after Bertha has enough stars and skills to hold a long-term role.
