Flaming Eyes of K'Varn (5e Equipment)

Weapon (flail), rare (requires attunement)

This flail-like weapon has two iron balls that are three inches in diameter connected by a 5 foot ethereal string. (The string cannot be affected outside the Astral Sea.) When attuned, the weapon deals an additional 1d4 fire damage and the weilder can make a ranged weapon attack by manipulating the ethereal string with a range of 20/60 ft.

When these two balls touch they produce a small consistent flame. When they are hit together as an action, they send fire out in a 10ft radius around the wielder. Those hit by the blast must make a DC 14 Dexterity saving throw to take half of the 3d6 fire damage.
