Magic Items

Wondrous Item, rare (requires attunement)
"This stone is the color of the ocean at midnight, a blue so deep it appears black, and is carved in the shape of a lidless eye."

"The blackened metal of this longsword has a sheen of red. The black leather-wrapped hilt ends in pommel shaped like a human skull. The longsword is inhabited by an orc warchief, K’tagh Redeye, a berserker who has a terrible loathing of humans. If K'tagh is banished or otherwise removed from the sword, the blade loses its red sheen."

"While holding the sword, the voice of K’tagh Redeye echoes in the wielder’s mind, cursing and nudging the owner to greater violence, especially toward humans. If the person wielding the sword is a human, K’tagh constantly casts insults and threats. The spirit cannot withhold the benefits of the sword from a wielder, however. You gain +1 bonus to attack and damage rolls made with this magic weapon."

Curse. This sword is cursed and possessed by a vengeful spirit. Becoming attuned to it extends the curse to you. As long as you remain cursed, you are unwilling to part with the sword, keeping it on your person at all times. While attuned to this weapon, you have disadvantage on attack rolls made with weapons other than this one. In addition, while the sword is on your person, you must succeed on a DC 15 Wisdom saving throw whenever you take damage in combat. On a failed save, you must attack the creature that damaged you until you drop to 0 hit points or it does, or until you can’t reach the creature to make a melee attack against it. You can break the curse in the usual ways. Alternatively, casting banishment on the sword forces the vengeful spirit to leave it. The sword then becomes a +1 weapon with no other properties.
