Stormspire is an Elite Unique Polearm with an item level of 89 and a Character Level requirement of 70.


Polearms are, along with spears, the largest weapons in the game with the longest reach. However, they are unpopular due to their relatively low damage and slow swing speed. They aren't even that good for Barbarians to use with Whirlwind, as they have much lower damage then the top maces or spears. They are improved somewhat at higher levels in the Expansion, however.

  • In 1.10 of the Expansion the odds of gambling a Unique is 1 in 2000.
  • Unique elite items are found only in the Expansion, never in Diablo II.


  • Item Level: Chests and monsters must be at least this level to drop the item. Ilvl is used in gambling, sales and other calculations as well.
  • Clvl Req: Your character must be this level or higher to equip the item. No Uniques had Clvl requirements prior to v1.07 D2.
  • Range: Goes from 1 (least) to 5 (most), and is identical for all melee weapon types. I.E. a 3 sword = a 3 spear = a 3 hammer.
  • Dmg Bonus: This determines how you multiply the item damage by your stats to reach the actual damage. Each point in this statistic multiplies your damage by bonus/100 %. For example a damage bonus of 70 is 70/100 or and additional .7% weapon damage per point. Most weapons have 100 str, which gives 100/100 or an additional 1% weapon damage per point in str.
  • Weapon Speed (WSM): A relative comparison to other weapons of the same type. 0 is the base -10, -20, etc is faster, 10, 20, etc is slower.
  • Swing Speed: The speed shown in-game for each character using this melee weapon. This speed is mostly meaningless and is included for completeness only. Characters are abbreviated to their first letters, with Amazon = Am and Assassin = As.
