I have a high level character who, through plot, became very very interested in Grafting. Fleshcrafting Poison seems to be Pathfinder's equivalent to Grafting, so I'll probably be picking up that feat. Assume that the CR can be no more than half the Caster Level, rounded up.
What type of monster abilities/stuff would you go for? What's flavorful and interesting? To an extent, I'll be playing Megaman, but this also opens up seeking particular monsters for their parts.
I'm not looking to hardcore power-game this (which is entirely possible), I'm looking for neat/flavorful things that can be done. Ultimately, the price would be considered a guideline and the GM as well as myself would adjust it up or down based on its power.
