Innate Spellcasting. The larva mage’s innate spellcasting ability is Charisma (spell save DC 16, +8 to hit with spell attacks). It can innately cast the following spells, requiring no material components:

• At will: eldritch blast (3 beams, +3 bonus to each damage roll), minor illusion

• 3/day: dominate monster

• 1/day: circle of death

Return to Worms. When the larva mage is reduced to 0 hit points, it breaks apart into a swarm of insects in the same space. Unless the swarm is destroyed, the larva mage reforms from it 24 hours later.

Actions

Slam Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 7 (1d8 + 3) bludgeoning damage, and the target must succeed on a DC 19 Constitution saving throw or be poisoned until the end of its next turn.

Plague of Worms (Recharge 6) Each creature other than a star spawn within 10 feet of the larva mage must make a DC 19 Dexterity saving throw. On a failure the target takes 22 (5d8) necrotic damage and is blinded and restrained by masses of swarming worms. The affected creature takes 22 (5d8) necrotic damage at the start of each of the larva mage’s turns. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
