Monster Manual
An angry buzz fills the air around a darting cloud of thousands of ruby-red insects.
Hellwasps are vicious, foul-tempered magical insects from the infernal planes. A single hellwasp resembles a thumb-sized normal wasp, except its carapace is gleaming black with ruby-red stripes, and its compound eyes are an iridescent green. In swarms, hellwasps form a collective hive mind intelligence with infernal cunning and bloodlust.
Combat
Like any swarm, a hellwasp swarm seeks to surround and attack any living prey it encounters. A swarm deals 3d6 points of damage to any creature whose space it occupies at the end of its move. The swarm can take over the bodies of its prey and infest both the living and the dead, using them as horrible living (or unliving) puppets to accomplish acts of wickedness that a swarm of insects could never attempt.
A hellwasp swarm's attack is treated as an evil-aligned weapon and a magic weapon for the purpose of overcoming damage reduction.
Distraction (Ex): Any living creature that begins its turn with a hellwasp swarm in its space must succeed on a DC 18 Fortitude save or be nauseated for 1 round. The save DC is Constitution-based.
Inhabit (Ex): A hellwasp swarm can enter the body of a helpless or dead creature by crawling into its mouth and other orifices. Inhabiting requires 1 minute, and the victim must be Small, Medium, or Large (although four swarms working together can inhabit a Huge creature). The swarm can abandon the body at any time, although doing this takes 1 full round. Any attack against the host deals half damage to the hellwasp swarm as well, although the swarm's resistances and immunities may negate some or all of this damage.
If a hellwasp swarm inhabits a dead body, it can restore animation to the creature and control its movements, effectively transforming it into a zombie of the appropriate size for as long as the swarm remains inside. If a hellwasp swarm inhabits a living victim, it can neutralize the effects of its own poison and control the victim's movement and actions as if using dominate monster on the victim. The hellwasps quickly consume a living victim, dealing 2d4 points of Constitution damage per hour they inhabit a body. A body reduced to Constitution 0 is dead.
A hellwasp-inhabited creature is relatively easy to spot, since its skin crawls with the forms of insects inside. The swarm is intelligent enough to attempt to hide beneath loose clothing or a large cloak to keep its presence from being detected. The swarm can attempt a Disguise check to conceal its inhabitation of a host, with a -4 penalty if currently inhabiting a Small host.
A remove disease or heal spell cast on an inhabited victim forces the hellwasp swarm to abandon its host.
Poison (Ex): Injury, Fortitude DC 18, initial and secondary damage 1d6 Dex. The save DC is Constitution-based.
Hive Mind (Ex): Any hellwasp swarm with at least 1 hit point per Hit Die (or 12 hit points, for a standard hellwasp swarm) forms a hive mind, giving it an intelligence of 6. When a hellwasp swarm is reduced below this hit point threshold, it becomes mindless.
