• 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 (This Calc have been implemented in Path of Building Community Fork as off 2.14. Choose "All Bolts in Range".). 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.

If using the Unleash or Spell Echo support gems, the chance to be Supercharged will be rolled for the entire sequence once, and all subsequent casts and projectiles will share a Supercharged state, if it occurs.

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