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.
It is unclear if Vel'Koz was the first Void-spawn to emerge on Runeterra, but there has certainly never been another to match his level of cruel, calculating sentience. While his kin devour or defile everything around them, he seeks instead to scrutinize and study the physical realm—and the strange, warlike beings that dwell there—for any weakness the Void might exploit. But Vel'Koz is far from a passive observer, striking back at threats with deadly plasma, or by disrupting the very fabric of the world itself.
