Band of Serpent's Jaw

A hide necklace interwoven with shards of the Frost Serpent's jawbone. Once a day, you can choose a creature or object of a size class no larger than you within 5 feet of you, and use an action to attempt to swallow it whole, unhinging your jaw as much as is required to do so. If the target is an unwilling creature who is not unconscious or incapacitated, it must make a Strength saving throw (DC 12) or be consumed; a creature consumed in this manner is considered blinded and restrained, and has total cover from attacks and effects taking place outside you. The creature is contained within your digestive system (but your outward appearance gives away no indication), and takes 2d10 acid damage at the start of each of your turns, or every minute if you're out of combat. You can have only one creature or object swallowed at one time, and a swallowed creature or object is released if you use an action to spit it up, die or fall unconscious, or take 20 or more points of damage from the swallowed creature or object, in which case you must make a DC 15 Constitution saving throw or regurgitate it.
