Challenger's Drinking Horn

Wondrous item, rare (requires attunement)

This hollowed ram's horn is black and banded with brass around its lip. Its curved shape makes it quite difficult to drink from in the hands of an amateur.

While attuned to this item, you will never become intoxicated from anything you drink from it. However, others who are not attuned to this vessel will become drunk from even the slightest sip of alcohol from it. The horn also allows you to belch noxious gas once per day after drinking from it, as the poison spray cantrip but using Constitution as your spellcasting ability.
