Avalon
SSR Holy Destroyer DPS

Arthur is an [Enhanced ULT] attacker: whenever a Supporter casts their ULT, she gets a 5-second window to fire an Enhanced ULT (720% + a 36% ATK self-buff). Her auto stacks Crit DMG per target hit and her passive stacks ATK/DEF after every ULT. Her damage ceiling literally depends on having a Supporter in the team: run her with one and she never stops casting.
