now I dun really like the idea alot but treat the heal/aid/fire rings as if they grant the spell yes, using stam Full stamina to cast it once. Would make it useful but at the same time useless in direct combat beyond a really low level because the ammount of healing compaired to stam would be insignificant. Although I'd prolly still carry one. for those instances where my cleric dies so that I could still get out without my other crits deing
