Necklace of Fireballs
Rare wondrous item
Property: A necklace of fireballs has 1d6 + 3 beads hanging from it. As an action, you can detach a bead and throw it up to 100 feet. At the end of its trajectory, the bead explodes in a 20-‐foot-‐radius cloud of flame. Each creature in the area must make a DC 13 Dexterity saving throw. A target takes 5d6 fire damage on a failed save, or half that damage on a successful one. You can hurl multiple beads or even the entire necklace as one action. The effect is the same as described above except that the explosion deals 1d6 extra fire damage for each additional bead after the first. The fire created by this item ignites combustibles. When all of its beads are expended, the necklace melts away.
Red beads in gold fittings hang from a delicate golden chain, and the ends of the chain can be tied together to form a necklace. The beads sometimes quiver, as if struggling to contain a powerful force.
