Voodoll Sprite

You summon a 1-HP doll within sight that obeys your mental commands. The doll floats up to 5 ft and can move 30 ft. You can command it to make an unarmed strike (+WIS to hit, 1d4 piercing). On death, it bursts in a cloud of pollen: creatures in a 5-ft radius must succeed on a CON save or be poisoned until the end of their next turn.
