I'm also interested.  Could alchemy (Potion, Salves, Gas Grenades, Poisons, Enhancement Drugs, Disease, etc) be considered as a use in a fighting style.

I wan't to make a healer and while they have magical capabilities, their more potent 'spells' are consumables.  The background of this character is a secret society of doctors that hire themselves out as battlefield medics.  They conduct their own magical research and the concept of Soul Stone could be something easily worked into their methods.  Perhaps they could even be rumored to commit the dark rituals of sentient species distillation.

Just wan't your two cents before crafting a character.
