3 words. Lazy Shell Armor! You could pretty much make Toadstool a god with that and the mortal ring. Hardly anything can damage her then, and she heals.
Really though, that was my first RPG, and it was damn good. I highly suggest getting the game on VC.
help her out alot? they make her in-fucking-vincible. they make her the most powerful shredder in any rpg ever. it would be hard to die after equipping that ish. real hard.
