Vel'Koz's abilities apply Organic Deconstruction to enemies on hit. If 3 stacks are accumulated, the enemy will take a burst of true damage.

Vel'Koz shoots a bolt of plasma that splits in two on reactivation or upon hitting an enemy. The bolt slows and damages on hit.

Vel'Koz opens a rift to the void that deals an initial burst of damage, then explodes for a second burst of damage after a delay.

Vel'Koz causes an area to explode, knocking up enemies, and knocking close enemies slightly away.

Vel'Koz unleashes a channelled beam that follows the cursor for 2.5 seconds that deals magic damage. Organic Deconstruction Researches enemy champions causing them to take true damage instead.
