Amuleta del Duendecillo

The Amuleta del Duendecillo is an abomination created by the Cleric Duendecillo de la Muerte that glows softly with a green, murky light which seems to be smothering a brightness at its core. The amulet retains the power of an abandoned deity of the Upper Planes, bound and channeled by the dark magic of Myrkul and the willpower of the wearer.

The amulet contains three (3) charges which allow the user to cast Radiant spells as Necrotic damage and Necrotic spells as Radiant damage. One (1) charge is expended per spell cast with the alternate damage type. One (1) charge resets on a Short Rest, all charges reset on a Long Rest.

When a spell is cast using the alternate damage type, both the caster and the target must make a DC 12 Wisdom Saving Throw. On a failed Saving Throw, the amulet also deals 1d4 damage of the original damage type dealt by the spell and the creature is Vulnerable to this damage type until the beginning of their next turn.

The amulet grants +1 to attack rolls for spells dealing Necrotic damage and -1 to attack rolls for spells dealing Radiant damage.

Notes: Must be a Cleric of Myrkul who has abandoned a deity of the Upper Planes.
