Endless Tankard of Toughness

Conjure a legendary tankard in your hands that can be passed around. Drinking from this tankard will temporarily grant you resistance to all nonmagical damage until your next turn. You may use a bonus action to drink from the tankard, and it contains a limitless magical brew. Each time you drink from the tankard, reduce your intelligence by 2, up to four times. If a creature drinks this brew more than four times in a day, it falls unconscious due to the strength of the magical brew.
