Damage Calculator Tool

Cyril Strategy

Use Player Phase Strategies

This map has no refresher enemies and you can reach some enemies right on the first turn, making this a perfect map for a Hit and Run strategy.

Using a ranged unit, defeat an enemy on the first turn and then retreat to safety using either movement skills like Reposition or by refreshing the initiator's turn.

The other enemies will approach and line themselves up to be cleaned up by your units on the following turns.

Tank Strategies are also viable

Tank strategies are also viable on this map with only a few enemies able to reach you on the first turn.

You can safely park a blue tank unit on the space below the unbreakable block and place some support units behind it; ideally two spaces away to avoid Cyril's Sudden Panic 3 debuffs. Only Cyril and the Lance Dragon will be able to attack that space.

Be aware that Cyril has the Null Follow-Up status from the Green Mage's Inf. Null Follow 3. Using a speedy blue tank is preferred if possible. If not, use a blue tank with high Def to reduce the amount of damage taken from Cyril.
