Storm star

Storm Star is a magical morning star of ancient design, thought to have originally been devised in Netheril. Many variants of the weapon exist, with most being cast in electrum-plated steel. They are among the longest and heaviest of morning stars, being of +1, +2, or +3 enchantment. Storm stars crackle with spectacular, though completely harmless arcs of lightning when wielded. This weapon allows it's wielder to unleash a more dangerous chain lightning spell as well.
