Guzzler

You can shotgun drinks like nobody's business. You can now drink potions as a reaction. You cannot use your reaction to drink a potion if you drank a potion as an action or bonus action.

In addition, once per day you may double fist potions to Belch: as an action, you may consume two potions at the same time in order to burp at an opponent within 10 feet of you, dealing 4d4 acid damage unless they pass a DC 13 dexterity save. For each potion, you may choose whether the effects apply to yourself or to the affected target; if you choose the target, the effect fails if they succeed.
