Having the option to use Vigor in some spells

Gee, how did I not think of increasing enemy defense? Lel. I guess I was afraid I might not get my stone wall enemies not be that impressive, but yeah.

Also, though I wasn't being clear, I actually wanted confirmation wether my formula would make battle power slighty less powerful and allow higher numbers/variety. I've been trying to make calcs and I can never seem to have a formula where Double Vigor equals at least more than double Battle Power.

But...I guess it makes sense? ...no, you can rather easily get a new weapon with double your battle power you had before while it would take like 16 levels to do the same with 36 stamina and a x2 boost...

Oh this is so confusing...I think I should just give up and actually continue with the hack instead of fighthing with this thing...
