Vaal Power Siphon

VaalPowerSiphon Vaal Power Siphon is a vaal projectile attack that fires a single wand projectile at each nearby enemy, granting a power charge for any slain by it.

Skill Functions and Interactions

Vaal Power Siphon fires one projectile at each enemy, meaning that if 20 enemies are present, adding Lesser Multiple Projectiles will cause 60 total projectiles to be fired. However each set of projectiles is able only to hit the enemy it targeted, and only with a single projectile. This means that additional projectiles created by support gems such as GreaterMultipleProjectiles Greater Multiple Projectiles Support and GreenBarrageSupportGem Barrage Support do not have any effect despite reducing damage. Other support gems, such as chain Chain Support, do result in each projectile being able to hit more than one target.

In terms of the range meant by "nearby" enemies, Vaal Power Siphon will target at least all enemies onscreen. This is an AoE calculation, so projectile speed does not affect the effective range.
