The rasping legs of this hideous, shining carpet of fist-sized ticks rattle ominously as the swarm skitters forward.
If a creature leaves a tick swarm’s square, the swarm takes 1d6 points of damage to reflect the loss of its numbers as several ticks cling to the victim. A creature with ticks clinging to it takes swarm damage at the end of its turn each round. As a full round action, the creature can remove the ticks with a DC 20 Reflex save. At least 10 points of damage from any area effect destroys all clinging ticks. The save DC is Dexterity-based.
The DC is Con-based.
Environment temperate forests
Organization solitary, pair, or colony (3–6)
Tick swarms are merciless blights, able to quickly reduce the larger animal life of a region they infest to blood-drained, diseased husks.
