Last War Crystal Boss: the lineup that scores

The rule that changes the lineup

Five heroes of the same troop type give +30% Attack. Mixing types removes it. The boss ignores troop-type advantage. Pick one type and keep all five on it.

• Solo boss. No rallies.
• 3 attacks a day, Monday to Saturday.
• Troops cannot be recalled.
• Phases follow the order on the battle screen: Cannon, Armor, Chip, Radar, Core.

Three lineups

2 front / 3 back.

Tank

Front

Back

Damage dealer: Kimberly.

Air

Front

Back

Damage dealer: DVA.

Missile

Front

Back

Damage dealer: Tesla.

Do not slot Mason or Sarah. They break the 5-same-type bonus.

How to spend the 3 daily attacks

• Weekly rewards use your single highest hit, not the sum of three.
• Still use all 3 attacks for the daily chest.
• Send your strongest mono squad all 3 times.
• Test another type with one hit only if that type is close in gear.
• Do not rotate Tank, Air, and Missile.
• Troops cannot be recalled.

Four mistakes

1. Slotting Mason or Sarah. They break the 5-same-type bonus.
2. Rotating Tank, Air, and Missile. Send your strongest mono squad all 3 times.
3. Skipping attacks because only the top hit counts. You still need all 3 for the daily chest.
4. Counting on temporary buffs. War Fever and Charge Banners do not apply to this boss.
