First off. Really liking the Summoner spell school (to be honest I like both of the new schools, they both bring a lot of utility and combination potential to the game) but I have noticed that there are no source skills for either Summoner or Polymorph (honestly thought that Skin Graft would be a Source skill).

I was thinking of a Source skill that could utilise body parts, much like how an elf can eat the body part for information or skills, a Summoner can expend the body part to summon the being in question to fight for them (Let's say Atusa could be summoned from her arm/leg whatever she drops when Dallis gibs her). I suppose that could be classed as Necromancy but the being in question would choose to come back (Lorewise not gameplaywise) I don't know. Was just a thought in my head. Gives a use to the body parts if there is no elf in the party.
