Storm Burst

Storm Burst is a Spell Channelling skill that creates orbs of energy which deal Physical damage, half of which is converted to Lightning damage, in an Area of effect. The orbs deal damage at an interval of 0.4 seconds over a Duration of 1.2 seconds.

Skill function and interaction
Channelling Storm Burst creates a cluster of pulsing orbs that follow the mouse pointer. Enemies can be hit by multiple orbs, but the orbs spawn in a spread out pattern resembling buckshot.

Each orb created has its own duration tracker. Every 0.4 seconds, the orbs will jump to a new location around the cursor and create an explosion. This 0.4 seconds interval is independent for each orb.


 * Area of Effect: Area of Effect modifiers affect the radius of the explosion caused by each orb, but does not affect the spread of the orbs from the cursor. Thus, increasing AoE will result in more overlapping explosions and higher hit rate.


 * Cast Speed: Cast speed modifiers affect the rate at which new orbs are created, but does not affect the jump interval (0.4s).


 * Skill Duration: Skill duration modifiers affect how long each orb stays on the ground before expiring and exploding. However, because the the skill deals damage at an interval of 0.4 seconds, investing in skill duration will only have a meaningful effect if it would bring the total duration to the next breakpoint in multiples of 0.4 seconds (i.e. 1.6 seconds, 2.0 seconds, 2.4 seconds, etc.) There is no difference between 2.01 seconds and 2.39 seconds, or any other duration that is not a multiple of 0.4.

Version history

 * Storm Burst's tooltip now displays the frequency at which Orbs jump and the duration of Orbs.


 * No longer fires projectiles.
 * Now creates orbs of energy while you channel that repeatedly jump towards the targeted location until their duration expires, dealing damage in small area after each jump. When you stop channelling, all remaining orbs explode, dealing higher damage in a larger area. This explosion deals more damage based on how much duration remains at the point you stop channeling [sic].
 * Now has a cast time of 0.25 seconds (from 0.65).
 * Mana cost at gem level 1 is now 2 (was 4).
 * Mana cost at gem level 20 is now 5 (was 10).
 * Now deals Physical Damage, and converts 50% of Physical Damage to Lightning Damage.
 * Now requires level 12 (from level 28).
 * Now deals 6 to 8 Physical Damage at gem level 1, up to 114 to 174 Physical Damage at gem level 20.
 * Now has an added damage effectiveness of 25% (from 40%).
 * Now gains additional radius as the gem levels.


 * Now deals 31-47 lightning damage at gem level 1 (up from 9-13), up to 183-275 lightning damage at gem level 20 (up from 50-76).
 * Now deals 65% more area damage (down from 250% more), triggered when channelling ceases.
 * Now has an added damage effectiveness of 40% (up from 10%). Area of effect increased by 10%.


 * Now correctly modified by factors based on the state of the projectile (such as Powerful Precision`s "Projectiles have 100% increase Critical Strike Chance against Targets they Pierce").


 * Storm Burst has been added to the game.
