Sea Devil's Sapphire

#wondrous-item #very-rare (requires attunement)

This silver pendant bears a small sapphire surrounded by all manner of strange and terrifying creatures. While wearing it, you can expend 1 charge as an action to speak this pendant's command word, granting yourself the terrifying visage of a devil for 1 minute. If a creature that isn't a fiend or undead starts its turn within 30 feet of you and can see you, it must succeed on a DC 15 Wisdom saving throw or become frightened of you for 1 minute. A creature that isn't surprised can avert its eyes to avoid the saving throw at the start of its turn. If it does so, it can't see you until the start of its next turn, when it can avert its eyes again.

While frightened, the creature is paralyzed. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the pendant's effect for the next 24 hours. Once used, this pendant can't be used again until the next dawn

Curse. The pendant is cursed. Attuning to it curses you until you are targeted by the remove curse spell, a dispel evil and good spell, or similar magic. Removing the pendant fails to end the curse on you. While cursed, you have a swim speed of 0 and sink 60 feet at the start of your turn if you are in water.
