What purpose would this go to?
You can feed different aspect of yourself.
This is how I see it: with the right herbs, potions and stuff, harvested and carefully selected, one aspect is honed, where others are neglected. Say, you want to focus on aramor wariors. Rare and stronger creatures, however, suffer a setback, or receive no bonuses.
Why not have an all white healer rite, that's so fast, it can not be destroyed. Powered by the right magical parafernalia and food, like mushrooms and stuff.
With an extra dimention of 'food' this can become a possibility.
