Elemental priorities and ignore damage...

I'm still trying like hell to wrap my brain around what your tring to accomplish.
In last line there regarding "no change" always being true. It will be because no other checks have made.
The promblem I have is figuring out why your trying to set a no change before anything else. If you dont want a change then why wouldnt you just remove any elemental flag from your attack for the sake of dmg calculation. Are you trying for a multi element attack that is treated with no change? At that point the game wouldnt need to handle it as ever having elemental dmg from the start.

Still not sure what your looking for (other than treating no change as an element itself) if thats the case, reduce the stregth of the spell and just ignore defense all together to balace is out, maybe?
