The enemies in the first half have Slash, Blunt, Ice, and Physical Plates.

First Half Stage 12 Strategy Tips
Tips for the First Half
- Use Slash, Blunt, Ice, and Physical Characters
- Target the Phaneroplasmodium in Wave 1
- Manage SP Carefully in Wave 2
Use Slash, Blunt, Ice, and Physical Characters
In the first half of Stage 12, enemies possess Plates to Slash, Blunt, Ice, and Physical Elements. Since 3 miniature enemies appear in Wave 1 and 1 midsized enemy in Wave 2, prioritize multi-target attackers capable of breaking all Plates simultaneously.
Target the Phaneroplasmodium in Wave 1
The central Phaneroplasmodium Yoju: Type 1225 in Wave 1 steals SP with its skill. SP is restored only after Core Exposing or incapacitating it. Prioritize its elimination first.
Manage SP Carefully in Wave 2
Wave 2 introduces a midsized Phaneroplasmodium Honju: Type 1225. This variant has higher HP and Resistance and may steal SP twice per turn. Focus on rapid Core Exposure to counter this threat.
Second Half Stage 12 Strategy Tips
Tips for the Second Half
- Use Slash, Ice, and Wind Characters
- Beware of Attack and Plate Nullification
- Defend against Blast & AoE Attacks
Use Slash, Ice, and Wind Characters
The second half boss, "Dimensional Identified Kaiju A: Divided Entity", has Plates for Slash, Ice, and Wind Attributes. Hikari Shinomiya (Slash/Wind dual Attribute) is highly recommended for stage-effect synergy.
| Tips! | The boss's Form Change stacks (up to 3 times), altering its attacks. All stacks reset upon Core Exposure. |
Beware of Attack and Plate Nullification
When the boss activates "Charging Stance", it nullifies one incoming attack and makes Plates unbreakable (marked with a slash icon). Neutralize this state first with a Normal Attack before targeting Plates.
Defend against Blast & AoE Attacks
The boss employs high-damage Blast and AoE attacks. While a Defender isn’t mandatory, a team boost character like Isao Shinomiya or Akari Minase can improve survival odds.

Break Plates Efficiently
In the "Flurry of the Frontline" Fierce Battle Area 12, the enemies' Plates are Slash, Blunt, Ice, and Physical in the first half, and Slash, Ice, and Wind in the second half. Break each Plate efficiently to expose the Kaiju's Core and gain an advantage in battle.
Level Characters to 90
If your level is lower than the enemy's during battle, the damage you take will increase, making it harder to complete the objective "Win with 0 incapacitated units." The enemies in Stage 12 are level 85 with high HP, so it's recommended to challenge them with characters at Lv. 90 or higher to increase your damage output.
