The following table is a list of 20 powerful items that can be crafted from monster body parts. It is written with my acid-fantasy 'City of Calyx' D&D setting in mind, but it's suitable for many other old school adventure game systems and settings.
In the wilderness beyond Calyx, beasts both
both alien and terrible stalk the crimson steppe. Merchants and loose lipped adventurers speak of creatures warped by aeons of arcane fallout, and of the magical bounty to be carved from their dead flesh. Monster bones and organs are sought after, and command a
high ransom of gold at the Calyx Bazaar. In the hands of a skilled craftman, these regents can be carefully formed into items capable of strange and powerful effects.
Roll on the following table to determine what monster part can be harvested from a magical beast and crafted into a usable item.
- Bones, talons, teeth- crafted into arrow clubs, blades, arrow tips & spear heads. Grants additional to hit bonus, cause extra damage
- Pheromone glands- grants a bonus to ability to intimidate or persuade
- Strong hide- resistant certain types of damage (bludgeoning, piercing, slashing, etc)
- Stomach acid- highly corrosive to a certain substance it touches (metal, flesh, stone, wood, glass, etc.)
- Gut- craft into powerful bowstring for increased firing rate, stronger & more accurate shots.
- Venom sac- poison causes deleterious effect when ingested or injected (paralytic, sleep, confusion, death)
