Cincture of the Stone King

The Cinture of the Stone King is a gray leather belt with square opals which was found on the corpse of the undead dwarf king in Thomara. It was given to Percival.

Description
Cinture of the Stone King is made of dark-grey leather and adorned with seven large, rectangular opals one to two inches across.

The attuned creature gains resistance to psychic damage. In addition, they are immune to being paralyzed or petrified and cannot be knocked prone. As an action, they can channel their anger to produce a shock wave of thunderous energy, as with the Thunderwave spell. The spell has a DC of 16 and is considered to be cast at fifth level. Once used, the owner of the belt cannot use this feature again until they complete a short rest.
