Having the option to use Vigor in some spells

Good work, both of you. I'm thankful for your effort at helping me.
I'm also a bit dense today. seibaby, how worse is the "level scaling" you mention ("It also makes physical abilites scale much worse with level, obviously.")? How much stronger would an attack made by a level 50 character with the same vigor and battle power than one of level 10? I don't remember what the scale was with vanilla, but for monsters (that have their vigor set randomly) being at a much higher level results in much, much more damage.

Madsiur, you mention stamina multiple times in your post...you do know I said "Use Vigor instead of Magic"? Or is stamina coded for Vigor? Maybe I'm missing something completely.

I'll thorougly playtest both and pick whichever suits me more...I'll let you guys know.
