Cauldron of Dyrnwch The Giant

Wondrous item, rare (requires attunement by a brave adventurer)

When you speak the command word this Medium- sized 50 pound cauldron glows red-hot. Any creature in physical contact with the object takes 2d8 fire damage. You can use a bonus action on each of your subsequent turns to cause this damage again. Liquid inside of the cauldron immediately comes to a roiling boil. If a creature is in the liquid, it must succeed on a DC 18 Constitution saving throw or gain one level of exhaustion in addition to taking damage.
