Shriek (Ex): When a doombat yips, all creatures (except other doombats) within a 100-foot spread must succeed on a DC 16 Will save or be overcome with uneasiness (-1 penalty on attacks rolls, checks, and saves) for 1d4+1 rounds while the doombat yips. The save DC is Constitution-based.

A doombat's yipping is constant, and spellcasters in the area must succeed on a DC 16 Concentration check anytime they attempt to cast a spell. The effect of several doombats yipping at once is not cumulative. A doombat must wait 1d3 rounds before yipping again. Whether or not the save is successful, an affected creature is immune to the same doombat's yipping for one day, though spellcasters are still required to make a successful Concentration check each time they attempt a spell so long as they are in the affected area.

Blindsense (Ex): Doombats use echolocation to pinpoint creatures within 60 feet. Opponents still have total concealment against the doombat unless it can actually see them.

Skills: Doombats have a +4 racial bonus on Spot and Listen checks. *These bonuses are lost if blindsense is negated.

Doombats attack any living thing they encounter. They enter melee and attack with their vicious bite and tail slash, yipping for the duration of the fight.
