Crown of Horns

D&D 2024 item: Crown of Horns. Source: The Lost Library of Lethchauntos. type Wondrous Item, Artifact rarity, Requires attunement The Crown of Horns contains the essence and intelligence of Myrkul, one of the Dead Three. This ghastly crown is a pale silver circlet with four curved bones set around its rim. On the crown's brow is set a black diamond whose depths swirl with weird, malignant energy.
