* marked abilities are exactly the same as the Ghost Bear Tribe Kobolds.
Hideous Spew (Su): Three times per day the possessed creature can generate a massive flow of stomach acid, showering its enemies in a blast of acidic spray that can strip away their fles. This ability affects all creatures in a 20-foot cone. They must make a Reflex save (DC 19) or suffer 2d6 damage. A successful save halves this damage.
Undetectable Aura (Su): At will as a free action, the possessed may choose to use its own or its victim’s alignment aura. Thus, spells such as detect evil may fail to uncover the presence of a possessing creature.
