Jester's Bracers

Loot of Nazramu, a djinn you "pulled" into your world using Spectacles of Spectacle during Zaviak's Vision Quest.

In-game description
"These bracers once belonged to a traveling bard famed for his sharp tongue and quick retorts. One rainy night, the bard took refuge in a rickety inn on the road to Shadowdale. There he performed for his supper, sprinkling his routine with caustic jibes as was his custom. One of the drinkers in the tavern, an old woman, stood up midway through the performance and snapped, "You think it clever to insult and belittle others? Do so, then, for as long as you live!" The bard found himself unable to remove his now-cursed protective bracers and was forced to spout corny jokes until he could pay a wizard to remove them."
