Seliph and Deirdre Strategy

Defeat Deirdre Quickly!

Deirdre has her Special ready at Turn 1 and possesses Sturdy Impact, which prevents follow-up attacks.

Due to this, she'll need to be taken out quickly. You can use a melee, physical damage unit as her Res is quite high.

Watch Out for the Cleric's Odd Recovery Skill

The Cleric has Odd Recovery 3, which will neutralize penalties and heal their allies on odd-numbered turns.

Keep this in mind if you're running debuff skills on your units such as Gravity+ or Panic Ploy 3.
