Flesh-Rotting Gaze (Su): Deals 1d6 damage, 30 feet, Will DC 16 negates. The save DC is Constitution-based.

See Invisibility (Su): A nothic can see invisible and ethereal creatures as though constantly under the effect of a see invisibility spell.

Skills: Nothics have a +4 racial bonus on Spot checks.

A nothic's claws are weak, and it is not exceptionally fast. Since it's perfectly happy eating carrion, it relies on its gaze to disable victims before moving in for a meal.
