Kay, I hope you do it sometime in the future :P but for now that isn't bad ;)

word

question, don't you always face forward when you are blinking? thus... u only ever have to subtract or do i misunderstand how it works

First off, welcome back. Second off it would work like this, lets make up some characters so you have an easier idea of what I mean. Say.... Iron Man... now if you know comics at all you know Iron Man has different sets of armours... from hulk buster to flying... etc... you make it so that if a player has one skill he cannot have access to a different skill... thus from a specific set of skills he can only have one or one maxed at any given time.
