I love the idea of powerful characters spooking the weaker monsters. Do that!
Gets rid of annoying battles and, like Xandria said, it\'d just be awesome to walk through the woods and have the animals scurry to get as far away from you as they can. That is, of course, if you\'re not good with animals
As for determining power levels, it occurs to me that you do have levels, it\'s just really easy to go up one and the delta is relatively small.
Just use the total number of points the character has recieved, right?
