Necklace of Harmonia

Wondrous item, legendary (requires attunement)

Hephaestus, as a wedding gift, made the necklace for Harmonia, the wife of Cadmus. Harmonia was the daughter of Ares and Aphrodite. It was passed down to several generations in the House of Thebes, but it always led to their ruin. The necklace is of an amphisbaena, with open mouths as if hissing. The two mouths on each side enclose with their jaws a golden eagle upright, its wings covered with yellow jasper and moonstone. The whole work is set with sparkling gems in masterly refinement. While wearing this necklace, your Charisma score increases by 2, to a maximum of 20. You have advantage on Charisma (Persuasion) checks made to interact with members of the opposite sex.

Curse. This necklace is cursed and becoming attuned to it extends the curse to you. Until the curse is broken with remove curse or similar magic, you are unwilling to part with it, keeping it within reach at all times.
