Storm star

A storm star was a magical morning star of ancient design, thought to have originally been devised in Netheril. Many variants of the weapon existed, with most being cast in electrum-plated steel. They were among the longest and heaviest of morning stars. Storm stars crackled with spectacular, though completely harmless, arcs of lightning when wielded.

This weapon allowed its wielder to unleash a more dangerous chain lightning spell called a battle bolt.

It was worth between 1,500 and 15,000 gold pieces.
