From the entry
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.

This horrifying cloud of ravenous, blood-draining parasites eschews the stealth of a lone leech's methods in favor of swift and merciless feeding.
