Fanged Warclub

Weapon (morningstar), rare

This oblong wooden weapon is crafted of hardened teak carved with a jagged edge and embedded with the shells, carapaces, and teeth of slain creatures. You gain a +1 bonus on attack and damage rolls with this magic weapon. In addition, when you hit a creature that has a bite attack, you can use a bonus action to knock out some of the target’s teeth, embedding them in the fanged warclub.

The target must succeed on a DC 14 Strength saving throw or else it takes disadvantage on attack rolls made with its bite for 1d4 rounds. The effect ends immediately if the creature hits you with its bite attack. As long as the creature’s stolen teeth remain embedded in the fanged warclub, it deals 1d10 piercing damage on a hit instead of 1d8.
