Care to give me some more thoughts about the balancing? I am a dungeon master and wanna use something like this for an RPG I might play with friends down the road :3 just a few details would be nice :3

So far the biggest issue I think is keeping aggro on multiple enemies. There are not many choices but I think Koutetsu is strong enough. Lastly, there is the fact that it's RNG heavy but at least there are many ways to manipulate it in your favor.
