Eustace

Anti-Social
The Anti-Social skill consumes all of Eustace's charge bar in exchange for the buff, which varies depending on Eustace's charge bar amount.

Each stack of (up to the maximum of five ) increases Eustace's Charge Attack damage and damage cap. The stacks are consumed after the Charge Attack.

boosts the next Charge Attack by 200%, but afterwards self-inflicts which prevents any charge bar accumulation for 5 turns. Note that is removable by skills such as Clear.
