A bit of an odd Buff Card, Ruin greatly increases the Party's ATK. But her secondary effect is what's sure to turn heads; Ruin can potentially wipe the Buffs of all enemy targets. Even more, the better the hand you make with Ruin, the greater the ATK Buff will be as well as your chances of wiping the targets' Buffs. That said, the Buff Wipe chance is awfully low, starting 20% and maxing at 35%. While a bit questionable for Dungeons, it can be potentially nasty in Colosseum.
