Greater Death Butterfly Swarm
The death butterfly swarm’s poison affects corporeal undead who are otherwise immune to poison.
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 points.
A creature in a space occupied by the death butterfly swarm has its speed reduced by half, and must succeed on a DC 16 Dexterity saving throw or become blinded. Both effects end when the creature doesn’t share a space with the swarm at the end of the creature’s turn. If a creature succeeds on the saving throw, it is immune to the swarm’s blindness (but not the speed reduction) for 24 hours.
