Stormspire is a unique Giant Thresher from Diablo II: Lord of Destruction. Strangely enough, Stormspire certainly does not have the highest damage output out of all unique polearms. However, its strength lies in its added Lightning damage. Besides the Lightning Damage it reflects onto attackers, Stormspire can also cast an extremely high level Charged Bolt when struck. Although not necessarily the most offensive spell, it is fun to watch and a good novelty.
