Sarah is an SSR Aircraft support hero in Last War Survival who specializes in improving the damage of back-row heroes against monsters. She also has personal damage reduction against monsters, making her useful for PvE progression and early Aircraft squads.
Unlike a dedicated attacker, Sarah’s main value comes from supporting the rest of the formation. She should remain in the back row, where she can strengthen nearby damage dealers while frontline defenders absorb incoming attacks.
Sarah is also connected to a later SSR-to-UR promotion opportunity during Season 4. This can affect whether players should continue collecting her shards or stop investing after replacing her in an early squad.
This Last War Survival Sarah guide covers her skills, skill upgrade priority, best gear, formations, strengths, weaknesses, UR promotion, and whether she is worth upgrading.
Sarah Overview
Sarah is an SSR support hero who belongs to the Aircraft vehicle type. Her main purpose is to increase the monster damage of three back-row heroes, making her particularly useful in PvE formations.
| Detail | Sarah Information |
|---|---|
| Hero | Sarah |
| Rarity | SSR |
| Vehicle Type | Aircraft |
| Specialty | Support |
| Damage Type | Physical Damage |
| Recommended Position | Back Row |
| Main Strength | Buffs back-row damage against monsters |
| Best Stage | Early to mid-game |
| Best Content | Monster battles and PvE progression |
| Long-Term Priority | Depends on Season 4 UR promotion plans |
| Formation Role | Back-row PvE support |
Sarah’s listed base stats at Level 60 include approximately 2,000 Attack, 56,200 HP, 361 Defense, and 189 March Size. Actual values can vary based on hero level, star level, research, buildings, decorations, gear, and server progression.
What Role Does Sarah Play?
Sarah is a back-row support hero. Her most important skill increases the damage that three back-row units deal against monsters.
This makes her useful when the formation already has strong damage dealers but needs additional PvE damage. Sarah does not need to be the main attacker because her value comes from improving the heroes positioned beside her.
She works best in formations with:
- Two durable frontline defenders
- Two strong back-row attackers
- Sarah in the remaining back-row position
Sarah should not normally be placed on the front row. Her support specialty and low defensive priority make her more effective when protected by tank heroes.
Is Sarah a Healer?
Sarah’s standard SSR skill set is focused on monster damage support rather than direct healing.
Her main support skill increases back-row damage against monsters. It does not function as a traditional healing ability, so Sarah should not be treated as a replacement for a dedicated sustain hero.
Her contribution is offensive support in PvE rather than restoring lost HP.
Sarah’s Role Before and After Season 4
Sarah’s role can change depending on the age of the server.
| Server Stage | Sarah’s General Role |
| Early server | Accessible Aircraft support |
| Pre-season progression | PvE and monster support |
| Early seasonal content | Secondary or temporary squad hero |
| Season 4 | Candidate for SSR-to-UR promotion |
| Post-Season 4 | Potential long-term Aircraft support after promotion |
Before Season 4, many players use Sarah as a temporary SSR support hero. Stronger UR Aircraft heroes may replace her in the main squad.
During Season 4, eligible players may receive an opportunity to promote Sarah from SSR to UR. Players planning around this promotion should be more careful about discarding her shards or completely ignoring her development.
Sarah Skills
Sarah’s SSR skills focus on regular Physical Damage, personal protection against monsters, back-row monster damage, and general stat improvements.
| Skill | Type | General Effect |
| Gunfire Negotiation | Auto Attack | Deals Physical Damage based on Sarah’s Attack |
| Special Armor | Passive | Reduces Sarah’s damage taken from monsters |
| MG Symphony | Tactics | Increases monster damage for three back-row heroes |
| Super Sensing | Expertise | Increases Sarah’s HP, Attack, and Defense |
Exact values may vary depending on star level, skill level, hero promotion, server version, and future game updates.
Gunfire Negotiation

Gunfire Negotiation is Sarah’s normal attack skill. At its listed base value, it deals Physical Damage equal to 38.70% of her Attack and has a cooldown of approximately one second.
Star upgrades increase the additional damage dealt by the skill.
| Upgrade Stage | Additional Damage |
| First upgrade | 20% |
| Second upgrade | 45% |
| Third upgrade | 70% |
| Fourth upgrade | 100% |
| Fifth upgrade | 150% |
Gunfire Negotiation allows Sarah to contribute steady basic damage while supporting the formation. However, her offensive output is lower than that of dedicated Aircraft attackers.
Players with limited Skill Medals should not prioritize this skill over MG Symphony. Sarah is normally included for her support effect rather than her personal damage.
Special Armor

Special Armor is Sarah’s defensive passive. At its listed base value, it reduces the damage she takes from monsters by 8.30%.
Each additional star effect improves the monster damage reduction by 2%.
| Upgrade | Additional Effect |
| Base effect | 8.30% monster damage reduction |
| First upgrade | +2% |
| Second upgrade | +2% |
| Third upgrade | +2% |
| Fourth upgrade | +2% |
| Fifth upgrade | +2% |
At maximum listed improvements, the total effect can reach approximately 18.30% damage reduction against monsters.
Special Armor is helpful in PvE because it allows Sarah to survive longer when enemies reach the back row or use area attacks. However, it only protects Sarah and does not directly improve the survivability of her teammates.
The skill also loses much of its value in PvP because its protection is specifically designed for monster battles.
MG Symphony

MG Symphony is Sarah’s most important SSR support skill.
At its listed base value, it increases the damage that three back-row units deal against monsters by 6.20% for five seconds. The skill has a cooldown of approximately nine seconds.
| Upgrade Stage | Improvement |
| Base effect | +6.20% monster damage for 5 seconds |
| First upgrade | Duration increases to 6 seconds |
| Second upgrade | Effect increases by an additional 2% |
| Third upgrade | Duration increases to 7 seconds |
| Fourth upgrade | Effect increases by another 2% |
| Fifth upgrade | Duration increases to 8 seconds |
At higher upgrades, MG Symphony can provide approximately 10.20% additional monster damage with an eight-second duration.
The long duration compared with the nine-second cooldown allows the formation to maintain the buff for most of the battle once the skill is fully improved.
MG Symphony affects all three back-row positions. This means Sarah benefits from the buff alongside the two damage dealers positioned beside her.
Why MG Symphony Matters
MG Symphony is the main reason to use Sarah in PvE.
A formation normally places its strongest attackers in the back row. By increasing the monster damage of all three back-row heroes, Sarah can improve the total damage of the squad rather than only increasing her personal output.
The buff becomes more valuable when Sarah is paired with developed attackers such as:
- DVA
- Morrison
- Schuyler
- Maxwell
- Other strong back-row damage heroes
Sarah’s value therefore depends partly on the strength of her teammates. A well-developed damage dealer gains more from the buff than an underleveled temporary hero.
Super Sensing

Super Sensing is Sarah’s Expertise skill. It increases her main personal stats.
| Stat | Listed Bonus |
| HP | +10% |
| Attack | +10% |
| Defense | +10% |
The Attack bonus improves Sarah’s regular damage. The HP and Defense bonuses help her survive area attacks and any enemies that reach the back row.
Super Sensing is useful in every type of battle because the stats are not limited to monsters. However, it does not directly improve the strength of MG Symphony’s percentage-based support effect.
Best Sarah Skill Upgrade Priority
Sarah’s best skill priority depends on whether she is used as a temporary SSR support or prepared for a future UR promotion.
General Skill Priority
| Priority | Skill | Reason |
| 1 | MG Symphony | Improves the monster damage of the entire back row |
| 2 | Super Sensing | Increases Sarah’s survivability and personal stats |
| 3 | Special Armor | Reduces Sarah’s damage taken from monsters |
| 4 | Gunfire Negotiation | Adds personal damage but does not improve her main support role |
MG Symphony should normally receive the highest priority. It provides the largest squad-wide benefit and defines Sarah’s role in a PvE formation.
Super Sensing is a practical second choice because it helps Sarah remain alive long enough to activate MG Symphony repeatedly.
PvE and Monster Skill Priority
Players using Sarah mainly for monster battles can follow this order:
- MG Symphony
- Special Armor
- Super Sensing
- Gunfire Negotiation
Special Armor becomes more valuable in difficult PvE battles where Sarah is taking area damage or the frontline is being defeated.
However, improving Sarah’s personal protection should not come before MG Symphony. Her primary purpose remains increasing the back row’s total damage.
Skill Investment Recommendation
Sarah does not require all four skills to be upgraded equally.
Players with limited Skill Medals should focus on MG Symphony and stop the other skills at practical milestones. Gunfire Negotiation can remain at a lower level because Sarah is not intended to compete with a dedicated damage hero.
| Player Situation | Recommended Skill Investment |
| Sarah is a temporary squad member | Upgrade MG Symphony only |
| Sarah is used regularly in PvE | MG Symphony first, then survivability skills |
| Sarah is in a secondary squad | Moderate or low investment |
| Preparing Sarah for UR promotion | Invest carefully and consider promotion refunds |
| Sarah is no longer used | Stop spending Skill Medals |
During Sarah’s Season 4 UR promotion, previously spent Skill Medals may be refunded as part of the promotion process. However, players should still avoid unnecessary upgrades before reaching that stage because those resources may be needed by the current main squad.
Best Gear for Sarah
Sarah benefits from a combination of offensive and defensive equipment, but she should not receive better gear than the squad’s main attackers.
| Gear Slot | Priority | Main Purpose |
| Cannon or Turret | 1 | Increases Attack and personal damage |
| Data Chip | 2 | Improves Attack, HP, and general stats |
| Radar | 3 | Helps Sarah survive Energy and skill damage |
| Armor | 4 | Adds HP and physical protection |
Although Sarah is a support hero, she still occupies a back-row position and contributes damage. Offensive equipment helps improve her attacks while defensive pieces prevent her from being defeated by area damage.
Early-Game Gear
Sarah can use available M3 equipment during early progression.
| Early Gear | Recommendation |
|
M3 Turret |
Useful early Attack increase |
|
M3 Radar |
Adds protection against Energy Damage |
|
M3 Armor |
Improves basic survivability |
|
M3 Data Chip |
Equip when available |
M3 gear should normally remain at Level 0. Blue equipment is replaced quickly, and Upgrade Ore is too valuable to spend heavily on temporary pieces.
Equip available gear for the base stats, but save major upgrades for Epic or Legendary equipment.
Mid-Game Gear
Sarah can use M4-A gear if she remains an active member of the formation.
| Recommended Gear | Main Benefit |
|
M4-A Destroyer Cannon |
Improves Attack and offensive stats |
|
M4-A Jackal Data Chip |
Adds Attack, HP, and general stat value |
|
M4-A Seahawk Radar |
Improves protection against Energy Damage |
|
M4-A Porcupine Armor |
Adds HP, Defense, and damage reduction |
The M4-A Destroyer Cannon is a useful first Epic item because it increases Sarah’s personal damage. The M4-A Jackal Data Chip is a practical second option for balanced offensive and defensive stats.
However, Sarah should not take these items away from a stronger main damage dealer. DVA, Morrison, or Schuyler will usually gain more from high-level offensive equipment.
Recommended Gear Upgrade Order
- Equip a suitable Cannon.
- Add a Data Chip.
- Upgrade Radar if Sarah is dying to Energy or skill damage.
- Upgrade Armor when physical attacks are the main problem.
Sarah does not need maximum gear investment to provide MG Symphony’s support effect. Keeping her alive is more important than trying to turn her into the squad’s primary damage dealer.
How Much Should You Invest in Sarah’s Gear?
| Player Situation | Gear Recommendation |
| Temporary early-game support | Basic M3 gear at Level 0 |
| Main PvE support | Moderate Epic gear |
| Secondary squad hero | Use transferred or spare equipment |
| Preparing for Season 4 UR promotion | Keep useful transferable gear available |
| Replaced by UR Aircraft heroes | Transfer her best gear to the main squad |
| Promoted UR Sarah | Reevaluate her gear based on the new skill set |
Gear can be moved between heroes, so equipping Sarah is less permanent than spending shards. However, Upgrade Ore should still be concentrated on heroes who remain important to the main formation.
Best Position and Team Formation for Sarah
Sarah should normally be placed in the back row.
MG Symphony affects three back-row units, making Sarah most useful when positioned beside two dedicated attackers. The frontline should contain two defensive heroes who can keep enemies away from the back row.
Recommended Formation Structure
| Position | Recommended Role |
| Front Left | Defensive hero |
| Front Right | Defensive hero |
| Back Left | Damage dealer |
| Back Middle | Sarah |
| Back Right | Damage dealer |
Sarah can use any of the three back-row positions. The exact slot should be adjusted based on enemy targeting and the survivability of the other back-row heroes.
Best Frontline Partners for Sarah
| Hero | Role with Sarah |
| Cage | Accessible SSR Aircraft defender |
| Carlie | Durable UR Aircraft defender |
| Lucius | Strong long-term Aircraft frontline hero |
| Murphy | Reliable defender for mixed early squads |
| Williams | Strong frontline protection |
| Scarlett | Accessible early defensive option |
| Violet | PvE-focused frontline option |
| McGregor | Missile defender for mixed formations |
Sarah needs enough time to activate MG Symphony repeatedly. Durable frontline heroes therefore provide more value to her than an extra fragile attacker.
Best Damage Dealers to Use with Sarah
| Hero | Benefit |
| DVA | Strong Aircraft damage dealer |
| Morrison | High back-row damage |
| Schuyler | Damage and control |
| Maxwell | Accessible SSR Aircraft attacker with monster bonuses |
| Kimberly | Strong damage option in a mixed formation |
| Tesla | Back-row damage for mixed squads |
| Swift | Missile damage option for a temporary mixed team |
MG Symphony is designed for monster battles, so it works best with heroes already capable of dealing high PvE damage.
Early-Game Sarah Formation
| Position | Hero |
| Front Row | Cage |
| Front Row | Best available defender |
| Back Row | Maxwell |
| Back Row | Sarah |
| Back Row | Strongest available attacker |
This formation is accessible for players developing an early Aircraft roster.
Cage provides frontline protection, Maxwell contributes additional monster damage, and Sarah increases the PvE damage of all three back-row heroes.
Budget Aircraft Formation
| Position | Hero |
| Front Row | Cage |
| Front Row | Carlie or another defender |
| Back Row | DVA |
| Back Row | Sarah |
| Back Row | Maxwell |
This lineup combines Aircraft formation value with Sarah’s monster damage buff.
DVA should receive the best offensive equipment, while Maxwell and Sarah can use secondary gear. Cage and Carlie protect the back row.
Aircraft Transition Formation
| Position | Hero |
| Front Row | Carlie |
| Front Row | Lucius or Cage |
| Back Row | DVA |
| Back Row | Sarah |
| Back Row | Schuyler or Morrison |
This formation can be used while developing a stronger Aircraft roster.
Sarah may eventually be replaced by another UR attacker before Season 4. Players planning to promote her later can keep collecting Sarah shards even if she temporarily leaves the main formation.
Mixed Beginner Formation
| Position | Hero Type |
| Front Row | Strongest defender |
| Front Row | Second defender |
| Back Row | Main attacker |
| Back Row | Sarah |
| Back Row | Second attacker |
A mixed formation can outperform a full Aircraft squad when the mixed heroes have higher levels, stars, skills, or gear.
Do not force five Aircraft heroes if doing so requires using several underdeveloped units. Sarah’s monster buff can still support back-row heroes from other vehicle types.
Post-Promotion Aircraft Formation
After Sarah is promoted to UR, her optimal formation may change because her promoted skill set is different from her standard SSR skills.
A general post-promotion Aircraft structure may include:
| Position | Hero |
| Front Row | Carlie |
| Front Row | Lucius |
| Back Row | DVA |
| Back Row | Sarah |
| Back Row | Morrison or Schuyler |
The exact choice depends on star levels, exclusive weapons, gear, and the content being played. Players should compare promoted Sarah directly with their available UR attackers before changing the main formation.
Best Uses for Sarah
Sarah performs best in battles involving monsters.
| Game Mode | Sarah Performance |
| Map Monsters | Good |
| Zombie Battles | Good |
| Campaign | Moderate to good |
| Wanted Bosses | Good |
| Monster-focused events | Good |
| Arena | Limited as an SSR |
| Standard PvP | Limited as an SSR |
| Main Late-Game Squad | Depends on UR promotion |
| Secondary Squad | Useful |
Map Monsters
Sarah can increase the total damage of the back row when fighting map monsters.
She is especially useful when the squad already survives the battle but needs more damage to defeat a stronger target or improve the result.
Zombie and PvE Battles
Both MG Symphony and Special Armor are designed for monster combat.
MG Symphony increases the back row’s damage, while Special Armor reduces the damage Sarah receives. This gives her a clear PvE role that is easy to understand and build around.
Campaign Progression
Sarah can help with campaign stages that use monster-type enemies.
Her performance depends heavily on the two attackers beside her. If those heroes are well-developed, the percentage damage buff can improve the overall formation more than adding another underdeveloped attacker.
Wanted Bosses and Damage Events
Sarah can be useful in boss fights if the target counts as a monster and her MG Symphony effect applies.
In damage-focused content, compare the following two setups:
- Sarah supporting two strong attackers
- A third dedicated attacker replacing Sarah
The better choice depends on hero development. Sarah becomes more attractive when her buff significantly improves two highly developed damage heroes.
Secondary Squads
Sarah can provide useful support in a second or third squad after leaving the main formation.
Her monster damage buff allows a secondary PvE squad to perform better without requiring another fully developed attacker. This can be valuable when multiple marches are needed.
PvP Battles
Standard SSR Sarah has limited PvP value because two of her main skills are focused on monsters.
MG Symphony increases damage against monsters, and Special Armor reduces damage from monsters. These effects normally provide little or no value against another player’s squad.
She can still be used temporarily if her level, star rating, gear, and skill development are much higher than the available alternatives. However, she should not be judged as a dedicated PvP support in her SSR form.
Season 4 and UR Promotion
Sarah becomes more important during Season 4 because eligible players may be able to promote her from SSR to UR.
This promotion gives Sarah a new skill set and can improve her long-term value. Players on younger servers should therefore consider future promotion plans before using all Sarah-specific shards without a strategy.
Sarah Strengths and Weaknesses
| Strengths | Weaknesses |
| Buffs all three back-row heroes against monsters | Most SSR skills have limited PvP value |
| Accessible SSR Aircraft support | Low personal damage compared with attackers |
| Useful for PvE progression | Depends on strong teammates |
| Works in mixed and Aircraft squads | Does not directly heal the squad |
| Personal damage reduction against monsters | Can be replaced before Season 4 |
| Can support secondary formations | Skill Medals may be better used on main heroes |
| Eligible for later UR promotion | UR promotion requires preparation and resources |
Sarah’s Main Strength
Sarah’s main strength is improving the damage of the entire back row against monsters.
Instead of only increasing her own performance, MG Symphony helps three heroes. This gives Sarah useful squad-wide value when paired with strong attackers.
Sarah’s Main Weakness
Sarah’s main weakness is that her SSR kit is heavily specialized for PvE.
MG Symphony and Special Armor are both connected to monster battles. When fighting other players, Sarah loses much of the value that makes her useful.
How Teammate Strength Affects Sarah
Sarah’s performance cannot be evaluated only through her personal damage.
Her buff becomes stronger in practice when it affects highly developed heroes. For example, increasing the damage of two well-equipped UR attackers can be more valuable than adding one weak temporary attacker to the formation.
Sarah performs poorly when:
- Her back-row partners are underdeveloped
- The battle does not involve monsters
- The frontline collapses too quickly
- She is expected to carry the squad’s damage
She performs better when:
- Two strong attackers stand beside her
- The enemy counts as a monster
- The frontline survives for several skill cycles
- MG Symphony is upgraded
Is Sarah Worth Upgrading?
Sarah is worth upgrading for players who need PvE support, use an early Aircraft formation, or plan to promote her to UR during Season 4.
Her investment priority is lower for players focused entirely on early PvP or those who already have a complete UR Aircraft formation and do not plan to use her promotion.
Upgrade Sarah When:
- She is part of your main PvE squad.
- You frequently fight monsters and zombies.
- You have two strong back-row attackers.
- You are developing an Aircraft formation.
- You have many Sarah-specific shards.
- You need support for a second or third squad.
- You plan to complete her Season 4 UR promotion.
Limit Sarah Investment When:
- You mainly focus on pre-Season 4 PvP.
- She is no longer used in any active formation.
- Your main attackers still need Skill Medals.
- Your frontline heroes are underdeveloped.
- You are using universal SSR shards without a promotion plan.
- You do not expect to promote her to UR.
Recommended Investment Level
| Player Situation | Recommendation |
| New player using Sarah in the main squad | Moderate investment |
| PvE-focused player | Prioritize MG Symphony |
| Early Aircraft player | Useful temporary support |
| Player with a full UR Aircraft team | Use mainly in secondary PvE squads |
| Player preparing for Season 4 | Collect shards and plan for UR promotion |
| Post-Season 4 player | Evaluate her promoted UR form |
Should You Upgrade Sarah to Five Stars?
Reaching five stars can provide two possible benefits:
- Improving Sarah’s standard SSR performance
- Meeting the requirement for her later UR promotion
Sarah must generally be at five stars before completing the Season 4 promotion. This gives players a stronger reason to develop her than many other temporary SSR heroes.
However, reaching five stars requires a large number of shards. Players should avoid spending universal SSR shards without checking their long-term priorities.
Sarah SSR-to-UR Promotion
During Season 4, eligible players may receive an opportunity to promote Sarah from SSR to UR.
The commonly listed promotion rules include:
| Promotion Detail | Requirement or Effect |
| Availability | Season 4 promotion event |
| Sarah requirement | Five-star Sarah |
| Promotion item | Legendary Hero Badge |
| Hero level | Remains unchanged |
| Star level after promotion | Resets to three stars |
| Skills | Reset and replaced with promoted skills |
| Skill Medals | Previously spent medals are refunded |
| Wall of Honor shards | Refunded under the promotion rules |
| Shards used to reach five stars | Not refunded |
| Time limit | Depends on the active promotion event |
After promotion, Sarah requires additional shards to rebuild her star level. Players should prepare SSR universal shards and Sarah-specific shards if they want to develop her promoted form quickly.
Should You Promote Sarah to UR?
Promoting Sarah is generally worth considering when:
- You already have her at five stars.
- You use an Aircraft squad.
- You can afford the post-promotion shard cost.
- You need a stronger support option.
- You have enough resources to rebuild her stars.
- You understand that her skills reset during promotion.
The promotion may be less urgent when:
- Sarah is far below five stars.
- Your Aircraft squad is not developed.
- Your resources are committed to stronger main heroes.
- You cannot rebuild her after the star reset.
- Another promoted hero is a higher priority for your account.
Players should treat the promotion as a long-term investment rather than a free immediate power increase.
Best Sarah Tips
- Keep Sarah in the back row.
- Place two strong attackers beside her.
- Use her mainly against monsters.
- Upgrade MG Symphony before her personal damage skill.
- Protect her with two durable frontline heroes.
- Equip M3 gear without spending Upgrade Ore on it.
- Give premium offensive gear to your main damage dealer first.
- Use Sarah-specific shards before universal SSR shards.
- Continue collecting Sarah shards if you plan to promote her in Season 4.
- Do not judge Sarah only by her personal damage report.
- Compare Sarah’s buff value with using a third attacker.
- Move her to a secondary PvE squad when stronger heroes replace her.
- Prepare extra shards before completing her UR promotion.
- Time major hero upgrades with suitable scoring events when possible.
Mistakes to Avoid
Placing Sarah on the Front Row
Sarah is a support hero with a back-row buff. Placing her on the front row exposes her to direct attacks and reduces the time she can keep MG Symphony active.
Use two defensive heroes in front of her whenever possible.
Treating Sarah as a Main Damage Dealer
Sarah deals Physical Damage, but her personal attacks are not the main reason to use her.
Her purpose is to increase the monster damage of the entire back row. Upgrade and position her as a support hero rather than expecting her to replace DVA, Morrison, or Schuyler.
Expecting Sarah to Heal the Formation
Standard SSR Sarah is not a traditional healer.
Her main support effect increases monster damage. Players who need healing, shielding, or general sustain should use heroes specifically designed for those roles.
Using Sarah Mainly for PvP
Sarah’s SSR kit is heavily focused on monsters.
Using her in PvP removes much of the value from MG Symphony and Special Armor. A dedicated PvP attacker or support hero will usually provide more consistent results.
Upgrading Gunfire Negotiation First
Gunfire Negotiation only improves Sarah’s personal damage.
MG Symphony affects three back-row heroes and normally provides better value. Players with limited Skill Medals should upgrade the support skill first.
Giving Sarah the Best Offensive Gear
Sarah can use offensive gear, but the squad’s main attacker should normally receive the strongest Cannon and Data Chip first.
Sarah can still provide her support effect with moderate equipment.
Upgrading M3 Gear
M3 gear is useful for filling empty equipment slots, but it is replaced quickly.
Keep temporary blue equipment at Level 0 and save Upgrade Ore for Epic and Legendary pieces.
Spending Universal SSR Shards Without a Plan
Sarah may eventually require five stars for UR promotion, but universal shards are still valuable.
Decide whether you are actively preparing for the promotion before committing a large number of universal SSR shards.
Ignoring the Post-Promotion Cost
Promoting Sarah to UR resets her to a lower star level under the promotion system.
Players who complete the promotion without enough shards to rebuild her may temporarily weaken her. Prepare resources before pressing the promotion button.
Ignoring Sarah After Replacing Her
Sarah may leave the main formation before Season 4, but that does not automatically make her shards useless.
Her later promotion opportunity means players should continue monitoring her long-term value, especially when building an Aircraft squad.
