Wondrous Item, common
A wonderfully carved spear thrower. It has a wooden haft the length of a human forearm and a bone handle near the base. Instead of a wooden prong a pointed tooth of some creature is used to hook the ammunition.
Adds 1d4 bonus damage to damage done with ranged spear-type weapons loaded into the spear thrower as part of your attack action.
Notes: Bonus: Ranged Attacks
