Strategy and Tips
Enhance your Characters

Kaiju in Promotion Exam 3 deal massive damage and can one-hit KO underleveled characters. It's recommended to bring at least 1–2 Level 90 characters equipped with strong Uniparts and Weapons.
How to Level Up FastEquip Strong Uniparts

Equipping strong Uniparts boosts both survivability and damage, making it easier to break PLT and cause Core Exposed on Kaiju. Be sure to check which Uniparts benefit each character the most before crafting.
Uniparts List and GuideTrigger the "Core Exposed" State

Breaking the Plates near a Kaiju's HP puts it into 'Core Exposed,' triggering your partner's Follow-Up attack. Use a team that can efficiently break these Plates.

Setup a Balanced Squad

'Core Exposed' breaks an enemy's Resistance, increasing damage dealt and delaying their actions. The key strategy is to support Attackers who can inflict Core Exposed with Defenders and Supports.
Example of a Balanced Squad
Slot 1 | Slot 2 | Slot 3 | Slot 4 |
Core Exposer & Attacker | Core Exposer & Attacker | Support or Attacker | Defender or Any |
Include Defenders to absorb damage, Supports to heal or buff, and Attackers to exploit Kaiju weaknesses. Synergy between roles, like pairing Core Exposed Attackers with Defenders and Supports, maximizes damage.
