Description
Blood Drain (Ex) Any living creature that begins its turn with a leech swarm in its space is drained of its blood and takes 1d3 points of Str and Con damage.
Poison (Ex) Swarm—injury; save Fort DC 15; frequency 1/round for 2 rounds; effect 1d4 Dexterity drain; cure 1 save.
This horrifying cloud of ravenous, blood-draining parasites eschews the s t e a l t h of a lone leech’s methods in favor of swift and merciless feeding.
A parasite ballooned to monstrous proportions undulates in the muck, its circular maw a spiral of teeth.
A mass of wriggling black creatures each the size of a man’s finger stirs the stagnant water before enveloping its victim.
