Amulet of Imhotep

This amulet has 4 charges and regains 1d4 + 1 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, a swarm of insects consumes and destroys the amulet, then disperses.

For each charge you are able to summon a humanoid shaped swarm of scarabs. As an action, you spend a charge and the ground in an area you choose within 30 feet erupts. Make an attack role on the nearest target as they are rushed by the swarm. The swarm can claw at or attempt to restrain your target using your skill modifiers.
