Stage Tips

Every four turns, the water Officer will be given high damage from the other two officers, so be careful on these turns.
Every three turns, the water Officer will make the other two take less damage.
The water officer takes no damage until the other two Officers are killed. You can defeat them in any order you like.

At the beginning of the fight, you will be granted a skill that requires you to guard to find the enemy's weak point.
- Guarding slots 1 or 2 will grant that unit the ability to paralyze the wood Officer.
- Guarding slots 3 or 4 will grant that unit the ability to put the dark Officer to sleep (it says paralysis but it lies).

At the end of turn 3 the water Officer will use an aoe bleed attack.
- Do not hit the wood Officer with a basic attack or you will be hit by an aoe that damages 50% max HP.
- Do not hit the dark Officer with an ultimate after this either since your units will all take more damage the following turn.
- This set of skills repeats at the end of turn 7, and every 4 turns after.

At the end of turn 5, all Officers will use their ultimates. The wood and dark ones target single units, while the water Officer will again use an aoe bleed attack.
- This set of skills repeats at the end of turn 9, and every 4 turns after.
