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 Lesser Multiple Projectiles SupportLesser Multiple Projectiles SupportSupport, Projectile

, 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.[1]

Version History

Version Changes
3.1.0
  • Radius has been reduced to 70 units (down from 120).
1.1.0d
  • Vaal Skill soul counts were initially balanced for Merciless difficulty, where there are more monsters. We want them to be easier to use in Normal and Cruel difficulty. We have halved the number of souls required for each skill. In Cruel difficulty, skills require 50% more souls to uses. In Merciless difficulty, they require 100% more (which is the same as before the patch).
