Storm Armor in action. Such as it is.

Storm Armor is a Conjuration Wizard skill unlocked at Level 17, shocking anyone in range of the Wizard.

  • This is an Armor spell. Only one Armor spell can be active at a time.

Storm Armor provides additional lightning damage that hits attackers automatically. It does not provide a defensive bonus to the Wizard, just another form of damage that generally activates only when the Wizard is hit. Some of the rune effects assist with other minor buffs.


Lacking physical armor, a Wizard needs magical protection in dangerous places. The Wizard weaves herself with electric energies that discharge if an enemy attacks her.

Skill Rune Effects[edit]

Refer to the Storm Armor rune effects article for thorough descriptions of all five rune effects in this skill, including screenshots, videos, strategy tips, and other related information.

Skill Design[edit]

This defensive skill shocks nearby enemies with lightning damage at seemingly irregular intervals. Also note that lightning critical hits will stun enemies, which would make this a lot more useful as a defensive spell, if the Wizard has a high chance to land a critical hit with spells (specifically lightning spells).


The following Wizard passives provide a benefit to Storm Armor, runed or not:

Name Level Description
Glass Cannon

1 Increase all damage done by 15%, but decrease Armor and resistances by 10%.

1 Lightning spells have a 15% chance to Stun all targets hit for 1.5 seconds.
Galvanizing Ward

1 As long as you have not taken damage in the last 5 seconds you gain a protective shield that absorbs the next 60% of your Life in damage.


Storm Armor was first shown at BlizzCon 2008 when the Wizard debuted. Back then, it was a Tier II skill in the Storm Skill Tree, and playable in the demo. However, it wasn't a popular choice; Flux explained why:[1] one was bothering much with defensive skills at Blizzcon; not in the short time we had to play, and the small dungeon we had to clear out. I didn’t test out this one, but it sounds like a fairly interesting skill. It’s somewhat misleading in name, since the description doesn’t mention any defensive properties; just that it fires out lightning bolts at nearby enemies.

It was seen again at BlizzCon 2009, but as a Tier V skill, it was too high level to try out. Skill tiers were removed for the July 2011 Press Event, allowing skills to unlock steadily from levels 1 to 30. Consequently, all skill levels were adjusted and Storm Armor became a level 13 skill.


The Diablo III Beta started in September 2011, and while it ran, all of the skills continued to undergo extensive iteration. Skill changes varied from changing the levels the skills are unlocked, to changes in resource cost, damage, and even function. A few skills were removed altogether, and a few new ones were added. Also, the entire skill system received an overhaul with the Beta Patch 13 update in February 2012, with physical runes replaced by rune effects that automatically unlock at various levels for the different skills.

Storm Armor was moved to level 12 soon after the beta started. Like all defensive skills, it wasn't very necessary in the beta, but Flux voiced a different concern:[2]

Just how the game defines “attackers” is not clear; I used this for a while and sometimes saw it hit monsters that I thought were not yet in melee range, while at other times it very slow to trigger even when I was getting swarmed. It’s hard to tell though, since the graphic for the shock it delivers to enemy monsters is very inadequate. It just gives them a little charge near the feet, almost like the Charged Bolt graphic from Diablo I. That’s very easy to miss if there’s a pack of enemies, much less if the Wizard is using lightning spells at the same time.

With the Patch 13 changes, Storm Armor was classified as a Conjuration skill and bumped up to level 17, moving it out of reach in the beta.

Previous Versions[edit]

See the Wizard skill archive for more details on previous versions of Storm Armor and other Wizard skills.

In Other Games[edit]

Storm Armor's operation is similar to Diablo II's Sorceress skill Thunder Storm, but there’s a key difference. While that (highly useful) skill zapped some random enemy with lightning once per second, Storm Armor only hits enemies that are attacking her.
