Nah.
I wouldn't want to use a Mickey and Broom on Illustrated Yuffie, but that's just me. I'd rather save those for 130% guilt medals.
With this update came new Adamantite quests. Treasure Trove Part 2 was a cake walk (I never needed a Friend Medal) but the Three Wishes Part 2...fuck. If I had a guilted CoM Riku (I'm one away) I could totally manage it by using a Friend Medal with poison to finish him off.
With the different medal set ups I've played with, the best I can get Cerberus to one turn is 2 health bars with perfect procs + poison.
First time outside of Coliseum where I've hit a wall.
