Ball Lightning is a spell that creates a moving ball dealing lightning damage.

Skill functions and interactions

Ball Lightning is a slow moving projectile, that strikes targets with bolts of lightning around itself. Lightning bolts strike targets every 150 milliseconds and each target cannot be hit more often than this. That restriction is shared between all balls fired on the same cast.[1] The base projectile speed is roughly 48 units per second.[2]

    has no effect as Ball Lightning automatically pierces targets. More details can be found on the Projectile page.

Damage per Second: DpS value on the skill tooltip assumes that the skill will do only one hit per cast, so you need to have an idea of the amount of hits it will do to get a better number, an estimate can be obtained using the calculator on the following link. It is worth noting that the calculation will not be very accurate for general use, as enemies will move around and the skill will pass over them using its entire diameter less often than not, however it should be fairly reliable when the skill is used on ranged attacking bosses as they tend to be stationary and the player will usually target them directly.
