Elemental Storm is a spell skill granted by the Stormweaver ascendancy notable Tempest Caller. This skill triggers when the user deals a Critical Hit with a spell. When triggered, it creates an elemental storm at the target location, dealing damage of the highest elemental damage of the hit that triggered it in that area for a duration. Enemies inside the storm are also Hindered.

Skill functions and interactions

Creates a stationary Fire, Cold or Lightning storm at a target location for a duration, based on the highest Elemental Damage type for the Hit that Triggered the storm. Hits which do not deal Elemental Damage will not Trigger the storm.

While it is usually desirable to create storms of a single, favored element, if a Stormweaver wants a mix of Elemental Storms, the Painter's Servant unique gloves and/or Elemental Conflux passive buff skill can be useful.

Despite Elemental Storm's Orb tag, it does not boost the damage of Eye of Winter. This may be a bug.

Despite the 0.1.0d patch notes claiming to have fixed it, Elemental Storm still sometimes appears beneath the Stormweaver, instead of at the targeted location. This is definitely a bug.

Version history

Version	Changes
0.3.0	The base damage scaling of all player spell and secondary damage skills has been tweaked to scale better in the late game. Generally speaking, spells that do not have damage number changes called out below will have near-identical base damage at low levels, roughly 5% more damage at gem level 20, and roughly 20% more damage at gem level 30. The Elemental Storm Skill granted by the Tempest Caller Notable Passive Skill has had its cooldown lowered to 3 seconds at all levels (previously 5).
0.2.0	Many Skills have had their base damage and/or damage growth per level rebalanced. Most of these changes are not specifically mentioned below as the changes are too widespread.
0.1.1	Fixed a bug where the "Elemental Storm" Gem had the Physical Tag.
0.1.0d	Fixed a bug where the Elemental Storm skill granted by the Stormweaver's Tempest Caller Ascendancy Passive Skill could sometimes place the storm underneath you.
0.1.0	Introduced to the game.
