Fork and Chain: Ball Lightning projectiles will always pierce, and therefore can never fork or chain
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.
Alternative quality

Ball Lightning was accidentally added to the game in an unfinished state in version 1.1.0 and was removed shortly afterwards.[3] It was officially added to the game in version 1.1.5. A history of the skill can be found in Supporter newsletter 73.
Note that helmet enchantments are no longer obtainable since version 3.23.0 and can only be obtained in permanent leagues as already enchanted items from before this patch.
Now deals 2-35 lightning damage at gem level 1 (up from 2-32), up to 22-420 lightning damage at gem level 20 (up from 14-260). Now has an added damage effectiveness of 35% (up from 20%).
The projectile's base speed is now 33% faster. The projectile hits 33% more frequently to compensate. The base radius has increased by 10%.
Disabled the "Reduced Ball Lightning Projectile Speed" enchantment from appearing.
Ball Lightning no longer has a 10% damage boost against players.
