Stitch also give you infinite MP while he's out, and even tho I use more spells than attacks, literally...
I still think all summons suck, except for gaining points in the colliseum tourneys. They can take my MP, they can take my allies, but taking drive points goes too far. But I leveled up summons too since I'm still on the way to 100% completion of all aspects.
75 hours play time and counting. The ending can wait.
