Orb of Storms

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 or . Each hit also has its own chance to cause "on hit" effects.

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.

The game also determines whether the orb can target an enemy based on the player's line of sight and not the line of sight of the orb itself. Placing an orb on the other side of a doorway may not guarantee it will attack a target even if it is right next to that target, but if there is a clear line of sight to the target the orb may even fire through walls as long as the target is within its radius.

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. However, the cast originates from the player location rather than the orb itself, meaning the bolt can hit an enemy outside of the orb's range. This secondary proc appears to not have an internal cooldown unless triggered by a channeling skill.
