Belt of Hill Giant Strength (Fat Markoth's Cummerbund)

Rare

Markoth – “Fat Mar” to those that didn’t truly know him – treasured this reinforced, velvety waistband above all other possessions. He wore it every day in life but was never able to fully grasp its benefits despite being attuned to it: while attuned, the wearer’s strength becomes 21 and, once per day, the wearer has advantage on one saving throw that might otherwise result in a level of exhaustion. While wearing this belt, your Strength score changes to 21. The item has no effect on you if your Strength without the belt is equal to or greater than the belt's score.
