When I make my level higher than 49, the game crashes, so apparently that level cap was intentional, and not just a bug. I can still make my stats super high though. I tried 500 Power and Control (it's a pain to find the value to change for those stats, so I just did these two) and it just wasn't fulfilling enough, so I did 1000. Now my regular arrow shot thing does 600 damage. Once PvP starts working, I shouldn't have too much trouble.
I can probably edit the bending moves so that cooldown time is lower, but that's really hard, and I'm just not that good. Judging by the top two Earth spots, it's also possible to change your score, so I'll try a few different things, but it looks like it'll be a pain.
