  • Fork and Chain: Ball Lightning projectiles will always pierce, and therefore can never fork or chain.
  • Tooltip damage: The tooltip DPS assumes that the skill will only hit once per cast. A more accurate estimate can be obtained using the calculator on the following link. It is worth noting that the calculation will not be precise for general use, as enemies will move around and the skill will not pass over them using its entire diameter. However, it should be fairly reliable when the skill is used on stationary targets. This calculation is also added to Path of Building Community Fork. Choose "All Bolts in Range" on main skill.

Alternative quality

The alternative quality Divergent Ball Lightning granted Projectiles have 0.5% chance to be Supercharged per 1% gem quality.

Supercharged Projectiles have 50% more Area of effect and deal 50% more damage.
