Notes[ | ]

  • The stat increase that can be applied by Res Opening is considered a Status Effect Bonus Bonus.
    • Any 【Bonus】 on a unit, including Status Effect Bonus Bonuses, lasts until the start of that unit's next phase. If Status Effect Bonus Bonuses are acquired during the enemy phase, they will disappear when the next player phase begins.
  • Unit selection takes place after all Status Effect Bonus Bonuses on allies are removed, and before any new Status Effect Bonus Bonuses or Status Effect Penalty Penalties are applied. All other existing Status Effect Bonus Bonuses and Status Effect Penalty Penalties count towards their respective stats during unit selection.
    • Res Opening does not compare Res stats, so 【Phantom】 effects will not work.
    • If multiple units are tied for the highest Res, each of those units will receive the effect.
