Why skill or will though? Does a large barbarian that knows how to smash monster faces in ten different ways really need to be magically attuned to be able to do it? Not at all.

Basing it off of any one or two stats is just not a good idea, for obvious reasons, it also messes with the fight rp.
'I cant use my ghost skills when i need them because I don't feel like it or because I cant use magic well enough to conjure the ability to do them.'

When it comes down to that, there's a problem. everyone has one stat that they want and will get. Along with one that they wont. Basing what you can do in combat on a stat that not everyone will be getting alot of it very pointless and unbalanced to me. The highest stat of the character is literally the best way to even the odds that have been stacked against every character that does not have buckets of will.
