Notes

• The stat increase that can be applied by Res Opening is considered a  Bonus.
  • Any 【Bonus】 effect on a unit, including  Bonuses, lasts until the start of that unit's next phase. If  Bonuses are acquired during the enemy phase, they will disappear when the next player phase begins.
• Unit selection takes place after all  Bonuses on allies are removed, and before any new  Bonuses or  Penalties are applied. All other existing  Bonuses and  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.
