Potent Poison. The death butterfly swarm’s poison affects corporeal undead who are otherwise immune to poison.
Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Tiny insect. The swarm can’t regain hit points or gain temporary hit point.
Weight of Wings. As death butterfly swarm but with DC 16 Dexterity saving throw
Actions
Multiattack. The swarm makes a Bite attack against every target in its spaces.
Bites. Melee Weapon Attack: +6 to hit, reach 0 ft., every target in the swarm’s space. Hit: 24 (6d6 +3) piercing damage, or 13 (3d6 + 3) piercing damage if the swarm has half of its hit points or fewer. The target also takes 17 (5d6) poison damage and becomes poisoned for 1d4 rounds; a successful DC 15 Constitution saving throw reduces poison damage by half and prevents the poisoned condition.
