Fun
Though I wish there was less RnG
I feel like if your attack has RnG baked in, then you should just weaken the effect/lengthen the cooldown. I had a crash with Poison Ivy, something about calling on effect animations. There's also the fact that Health carries over from battle to battle. I don't mean to badger you about the small details of a rough demo, but it is a little annoying to have to heal up in grind battles before taking on larger challenges if I forget to take the time to restore.
(oh and weaken regeneration down to 5-8%)
