Oh, hey, I've a tip for you guys, If you are having trouble with anyone except Florin, Do the surf glitch. It makes it so you are always surfing, Thus every battle you do will be on the Water surface field. It's not to difficult to do either. All you have to do is aggressively spam Z or Enter or whatever you bound it to While running towards Tesla's Yacht in Akuwa town. First, It will ask if you wanna surf, then it will ask you where you want to go. Go wherever and this should be the result:
If you want to make your character normal again, just go into water then come back
on land.This is very useful against Amber and Angie to name a few.
