After the comments, Chalchiuhtotolin is an avatar of Tezcatlipoca, and a benign one. He is not vomiting but uttering a stream of jewelled or sacred water. Maybe it could be kind of Heal Spray instead of Acid. Plus Awe, Animal Awe and Terror, the Turkey's gaze, a natural ability to collect blood slaves due to his symbolic posture as a media for man/god/man exchanges via ritual and sacred liquids : blood & water.
This one is great anyway. I want it in the game !!
