Horn of the Deep Ones

Wondrous item, rare (requires attunement)

This horn is crafted from a nautiloid shell, and it is constantly wet with a brackish slime. As an action once per day you sound the horn’s sonorous call summoning 8 troglodytes to serve you for 10 minutes or until slain. As part of the call, they each have +2 to all attacks and saving throws. If all of the troglodytes are slain, you must succeed at a DC 8 Fortitude saving throw or vanish into the horn and be turned into a troglodyte as if by the spell polymorph and be bound to the horn’s call for the next 24 hours (you appear as one of the summoned troglodytes). Regardless after 24 hours the effect ends.
