Disease (Ex): A creature struck by a tomb mote's bite attack must make a DC 13 Fortitude save or be infected with a disease known as corpse bloat (incubation period 1d3 days, damage 1d6 Str). The skin of a diseased victim turns a hue of green, bloats, and is warm to the touch. The save DC is Charisma-based.

Quickness (Su): A tomb mote is supernaturally quick. It can take an extra standard action or move action during its turn each round.

Tomb motes typically attack from ambush due to their size. If possible, they attempt to attack a foe en masse.

Tomb motes sometimes spontaneously arise in graveyards with a high concentration of buried magic, undead activity, and/or mass burials. As accumulations of grave detritus, tomb motes are surprisingly smart and vicious.

Tomb motes weigh 5 to 8 pounds and measure no more than 1 foot in height.
