Orb of Storms is a lightning spell that lays down a lightning orb that zaps an enemy within its radius for lightning damage. When the user casts a lightning spell within the orb's radius, the orb's attack frequency increases.

Skill functions and interactions

Each individual cast from the orb acts like its own unique spell, much like a totem casting. Each hit has its own chance of being a critical strike, while other hits from the same orb may only do normal damage, unlike other skills with multiple hits like FirestormFirestormSpell, AoE, Duration, Fire

The orb is always summoned next to the player at approximately the same distance.

The orb will only target enemies within its circle of influence, but the secondary chain hits can target enemies much further away and even slightly off the edges of the screen.

Despite being an Area of Effect skill, Orb of Storms DOES NOT benefit from Area of Effect damage bonuses, but effects that change the Area of Effect-radius will adjust how far out the orb will target enemies.

The secondary proc of the orb is the same effect produced from the orb itself, and the bolts split to hit multiple targets. This secondary proc appears to not have an internal cooldown unless triggered by a channeling skill, which can only trigger the orb every 0.5 seconds.

The orb does not have a duration. However, it will disperse after a certain number of hits.

Version history

Version	Changes
3.23.0	Quality now causes Beams to Split towards 0-2 additional targets, instead of providing 0-20% increased Lightning Damage.
3.17.0	Orb of Storms has been redesigned as a single target tool for lightning casters: Now deals 3 to 8 Lightning Damage at gem level 1 (previously 2 to 7), up to 304 to 913 at gem level 20 (previously 185 to 555). Now strikes every 3.50 seconds at gem level 1 (previously 1.50 seconds), and every 2.55 seconds at gem level 20 (previously 1.02 seconds). Beams now split towards 3 additional targets at all gem levels (previously 2 additional targets at gem level 1, up to 4 at gem level 20). Now has 110% Effectiveness of Added Damage at all gem levels (previously 65%). No longer requires splitting from the caster when they cast a Lightning spell in its area. Instead it will zap an enemy in range every time you cast a Lightning spell from within the Orb of Storm's area, making positioning much more flexible. No longer has a duration. Instead, it now has "Orb disappears after 10 Strikes" at gem level 1, up to 29 at gem level 20. Quality on Divergent Orb of Storms now has "Penetrates 0-5% Lightning Resistance" and "Orb disappears after 0 to -5 Strikes". It no longer has "0-20% less Skill Effect Duration" or "0-20% increased Cast Speed".
3.13.0	Got the Orb tag.
3.11.0	The visual effects have been improved. Now has an added Damage effectiveness of 65% (from 70%). An error which caused Orb of Storms' strike frequency to benefit doubly from increased cast speed was fixed, which has affected the balance of this skill, particularly for high cast-speed builds.
3.9.0	Now deals 2 to 7 Lightning Damage at gem level 1 (from 3 to 9), up to 185 to 555 at gem level 20 (from 195 to 584). Now strikes every 1.5 seconds at gem level 1, up to 1.02 seconds at gem level 20 (from 1 second at all gem levels).
3.6.0	Mana Cost at gem level 1 is now 4 (was 11). Mana Cost at gem level 20 is now 16 (was 28). Now deals 3 to 9 Lightning damage at gem level 1 (from 2 to 5) and 195 to 584 Lightning damage at gem level 20 (from 118 to 353). Now has an added damage effectiveness of 70% (from 45%).
3.5.0	Added physics interactions.
3.4.0	Can now be cast by mines, traps, totems, and can be triggered.
3.3.0	Now deals 2-5 lightning damage at gem level 1 (up from 1-3), up to 118-353 lightning damage at gem level 20 (up from 59-177). Now has an added damage effectiveness of 45% (up from 20%). Increases to cast speed now affect Orb of Storms strike rate.
3.1.0	Orb of Storms can now trigger lightning strikes from channelled skills.
3.0.0b	Using channelled lightning skills will no longer trigger Orb of Storms.
2.6.0	Now has a base skill duration of 6 seconds (down from 10).
2.2.0	Added to the game
