A shadow swarm can be difficult to see in dark or gloomy areas but stands out starkly in brightly illuminated places.

A shadow swarm is a group of 8-10 weightless shadows 4 to 5 feet tall. Shadows cannot speak intelligibly, but emit high-pitched shrieks when they fly in swarms.

Combat

Shadows hunt in the night sky, traveling great distances.

Strength Damage (Su): The touch of a shadow swarm deals 1d4 points of Strength damage to a living foe. A creature reduced to Strength 0 by a shadow swarm dies. This is a negative energy effect.

Create Spawn (Su): Any humanoid reduced to Strength 0 by a shadow swarm becomes a shadow and joins the swarm within 1d4 rounds.

Shadow Jump (Su): A shadow swarm has the ability to travel between shadows as if by means of a dimension door spell. The limitation is that the magical transport must begin and end in an area with at least some shadow. A shadow swarm can jump up to a total of 20 feet each round in this way; this may be a single jump of 20 feet or two jumps of 10 feet each. Every two HD higher than 7, the distance a shadow swarm can jump each round doubles (40 feet at 9, 80 feet at 11, and 160 feet at 13). This amount can be split among many jumps, but each one, no matter how small, counts as a 10-foot increment.

Skills

Shadow swarms have a +2 racial bonus on Listen and Spot checks and a +4 racial bonus on Search checks. *A shadow swarm gains a +4 racial bonus on Hide checks in areas of shadowy illumination. In brightly lit areas, it takes a -4 penalty on Hide checks.
