Skill functions and interactions

This article needs cleanup to meet quality standards.

Please help improve this article if you can.

Power Charges: Power Siphon gains extra Critical Strike Chance and Multiplier per Power Charge. Projectiles from this skill have a chance to grant a Power Charge on hit against rare or unique enemies. Projectiles from Power Siphon also apply a short debuff to any enemies hit, which grants a Power Charge to the user if the enemy dies.

"...granting you a power charge if an enemy is killed by, or soon after, the hit.": Enemies killed within 0.5 seconds of taking damage from a Power Siphon's hit will explode, even if killed by a minion or ally. This duration is inherent to the skill and is not modifiable in any way.

Culling Strike: All projectiles from this skill have Culling Strike, causing them to instantly kill enemies that have 10% or less life after being hit.

Dual Wielding: Power Siphon will alternate wands while dual wielding.
