Cannot be flanked and not subject to critical hits.Immune:mind-affecting effects (charms, compulsions, morale effects, patterns and phantasms), stagger, weapon damageWeaknesses:Half again as much damage (+50%) from spells or effects that affect an area, such as splash weapons and many evocation spells.
Offense
Melee:swarm (2d6 plus poison) Poison—injury; save Fort DC 14; frequency 1/round for 4 rounds; effect 1 Con; cure 1 save. This poison also affects undead creatures, dealing 1 Cha damage/round.
Special Attacks:
Distraction
(DC14)
Any living creature that takes damage from a creature with the distraction ability is nauseated for 1 round; a Fortitude save negates the effect. Spellcasting or concentrating on spells within the area of the swarm requires a caster level check (DC 20 + spell level). Using skills that involve patience and concentration requires a DC 20 Will save.
Weight of wings
(DC16)
Creatures affected by the swarm’s distraction effect must also make a Will save or suffer from the effects of Hold Person. This paralysis only lasts as long as the victim is within the swarm.

SQ:
Defeating a Swarm
Reducing a swarm to 0 hit points or less causes it to break up, though damage taken until that point does not degrade its ability to attack or resist attack. Swarms are never staggered or reduced to a dying state by damage.
Ecology
Organization:solitary, pair, or cleansing (3–5 swarms) ; 5,000 Ash Moths per swarm.
