Champagne Saber

Weapon (scimitar), uncommon (requires attunement)

While this weapon is on your person, you can't become drunk from nonmagical alcohol. When you hit a creature with this weapon and roll the highest number on its damage die, that creature must also succeed on a DC 13 Constitution saving throw or become poisoned until the start of your next turn, as the weapon's alcoholic magic overcomes it. If the creature fails the saving throw by 5 or more, it also falls prone.
