Tick Swarm

The rasping legs of this hideous, shining carpet of fist-sized ticks rattle ominously as the swarm skitters forward.

Cling (Ex)

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.

Disease (Ex)

Bubonic Plague: Bite—injury; save Fort DC 21; onset 1 day; frequency 1/day; effect 1d4 Con damage, 1 Cha damage, fatigue; cure 2 consecutive saves.

The DC is Con-based.
