Ball Lightning

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 200 milliseconds and each target cannot be hit more often than this. That restriction is shared between all balls fired on the same cast. The base projectile speed is roughly 36 units per second.

• and increase the number of projectiles, and thus the area of effect. However, since a target cannot be hit more than once within 200 ms, it cannot be used to "shotgun" the target by hitting them with multiple projectiles at once, leading to a possible DPS loss.
• Balls cast by do not share the 200 ms cooldown between each other because every trap counts as a separate "cast".
• 's second cast does not share the 200 ms cooldown with the first one.
• increases the range of the bolts fired from the lightning balls.
• and "Area of Effect damage" passive nodes do not increase Ball Lightning's damage (changes to Area of Effect radius still apply).
• increases the amount of time the enemy spends within the ball's area of effect, resulting in a higher potential number of lightning strikes per cast.
• effects the lightning bolts coming off of the ball (similar to Arc , but not the ball itself.
• 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.
