Cling to Shadows (Ex) Whenever a creature leaves a shadowmite swarm’s square, it immediately takes swarm damage as the shadowmites cling to its shadow. Immediately after dealing this damage, the clinging shadowmites return to the swarm.
Feast of Shadows (Ex) Whenever a creature in an area of dim light or darkness takes swarm damage from a shadowmite swarm, that creature takes 1d4 points of Constitution damage as its flesh is stripped away by shadow-empowered mites.
Sunlight Powerlessness (Ex) A shadowmite swarm is utterly powerless in bright light, such as natural sunlight, and flees from it. A shadowmite swarm caught in such light loses its cling to shadows ability and its swarm attack, and can take only a single move action each turn.
