Today, I defeated Cutie Pi; Wooly Wool whatever and got myself a fourth Unearthly Bun.
Hasten World + Rampant was actually good to use, judging Victor kept using Moderation to recover BP points under the negative. I defeated them on my second try, but I was so close to the first try until my party was weakened enough for Bone Crush to crush my party bones fatally. (Speed is good, people!)
Eesh, that move should NOT work for bosses.
