Chopper & Robin (6★ DEX/PSY, No.4319) · OPTC

Special

Hurrying the Search

Heals 25% of crew's maximum HP, heals crew by 5x character's RCV at end of turn for 10 turns, reduces all enemies' damage reduction (except [Damage Cut]) duration by 7 turns, and boosts DEX, PSY, Fighter, and Cerebral characters' base ATK by +1750 for 3 turns. If crew has base ATK boost when Special is launched, boosts the chain multiplier by 1.75x for 3 turns. If crew has base ATK boost and multiplicative chain multiplier boost (except additive boosts) at the same time when Special is launched, boosts crew's ATK based on the damage reduction effect applied on the crew (e.g. if crew has 80% damage reduction, boosts ATK by 2x) for 1 turn, then becomes "Chopper & Robin" for 3 turns
