A friend and I came up with this idea while talking about Morn, a character from Star Trek: Deep Space Nine, who stored a bunch of liquid money in one of his stomachs. I decided to write a real rule on it. Anyway, I hope you find it as amusing and cool as we do.
Digestive Gland (Ex): Kobolds have a large gland that branches off their esophagus and is in parallel with their stomach. A kobold pumps stomach acid into the gland, and when threatened, she can vomit out the acid onto her pursuer to help facilitate escape. A kobold can use this attack against a target up to 5 ft. away. The target must make a DC 10 reflex save or be blinded for 1d2 rounds. The DC is constitution based. The odor of the acid is stronger than skunk musk and can not be removed from clothing with mundane cleaning. Additionally, the digestive gland serves as an additional item slot, like that of an embedded item. This slot holds up to one small item. A kobold storing any items in her digestive gland, will eject the items when using the gland as an attack.
