Skull Chalice of Ch'gakare

The Skull Chalice of Ch'gakare was a legendary but non-magical artifact used as a symbol of office for the rulers of Omu in Chult.

Description
The chalice was constructed from a human skull and encrusted with jewels. In the 1490s DR, it had an intrinsic value estimated at 2,500 gold pieces, but collectors in large cities might have bid as much as 10,000 gp to own it.

History
The skull used in its construction was reputedly from an ancient king of Omu that was beheaded by the hero Ch'gakare after riding a mastodon out of the Nine Hells. It was desired by princess Mwaxanaré to help solidify her claim to the throne of Omu.
