Return to Worms. When the larva mage is reduced to 0 health, 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.

Spellcasting. The star spawn larva mage is a 20th-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 17, +9 to hit with spell attacks). It has 30 mana, a mana limit of 5, regains all expended mana when it finishes a long rest and regains half its total mana when it finishes a short rest, and knows the following spells:

Cantrips (at will): poison spray, poison

1 mana: confusion poison, detect poison, poison burst, protection from poison, putrefy food and drink, ray of sickness, slowing poison, toxic fumes

2 mana: cloudkill, halo of spores, insanity mist, mind control, noxious plume, paralytic poison, poison bane, stinking cloud

Actions

Slam. Melee Weapon Attack: +8 to hit, reach 3 m. Hit: 7 (1d8 + 3) bludgeoning damage, and the target must succeed on a DC 19 Fortitude 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 3 meters of the larva mage must make a DC 19 Reflex 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.

Reactions

Feed on Weakness. When a creature within 6 meters of the larva mage fails a saving throw, the larva mage gains 10 temporary health.

Legendary Actions

The star spawn larva mage can take 3 legendary actions, choosing from the options below. Only one legendary option can be used at a time and only at the end of another creature’s turn. The star spawn larva mage regains spent legendary actions at the start of its turn.

Cantrip (Costs 2 Actions). The larva mage casts one cantrip.

Feed (Costs 3 Actions). Each creature restrained by the larva mage’s Plague of Worms takes 13 (3d8) necrotic damage, and the larva mage gains 6 temporary health.
