This necklace has 1d6 + 3 beads hanging from it. You can use an Action to detach a bead and throw it up to 60 feet away. When it reaches the end of its trajectory, the bead detonates as a 3rd-level Fireball spell (save DC 15).

You can hurl multiple beads, or even the whole necklace, as one Action. When you do so, increase the level of the Fireball by 1 for each bead beyond the first.

A bright streak flashes from your pointing finger to a point you choose within range then blossoms with a low roar into an explosion of flame. Each creature in a 20-foot radius Sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 fire damage on a failed save, or half as much damage on a successful one.

The fire spreads around corners. It ignites flammable Objects in the area that aren't being worn or carried.

At Higher Levels: When you cast this spell using a spell slot of 4th Level or higher, the damage increases by 1d6 for each slot level above 3rd.
