Could I change the physical shape of a living monster into some kind of weapon, equip it with a ring of sustenance, and wield it against my enemies to defeat the same kinds of damage reduction as the monster normally can?
When I say its physical shape, I don't think I mean using Polymorph Whatever. I mean just sculpting and reshaping its still-living flesh, removing the parts that don't serve the purpose I want it to have, and fusing together its bones and joints so it doesn't bend in ways I don't want it to -- so that I can make the monster into an effective weapon. Like an axe, a dagger, a rapier or a scythe. But still a... kobold, phase wasp, kruthik or arrowhawk.
Do you know what I mean?
