Maybe you could make it so some of the customized items for throwing could be toggled on for sticking in the enemies. Imagine chucking a diamond axe and hitting some schmo in the head, and then it's stuck in there until you either go up and tear it right back out of their cranial vault, or put them out of their misery to where it drops like an item. Fun if using cheap weapons since you make some bugger look like a porcupine, and able to be toggled at the user's leisure. Well,... that and payback to those skeletal buggers. A sword through the squamous of their frontal bone'll theach'em for arrowin' my arm.
