Active: Zerko teleports to a visible location after a 1 second channel, dealing magic damage to enemies in a 400 range of where he lands. The cooldown of this ability changes depending on how far he teleported. Aditionally, it initiates a 1 second global cooldown on his abilities.
Magic damage: 100 / 250 / 500 (+50% AP)
Teleport is a ground targeted, area of effect ability.
The equation for the cooldown is distance/(100-min(distance/(100+distance/250),80)), causing a 950 second cooldown if he teleports from one nexus obelisk to the other, and a 100 second cooldown at 5500 distance.
The ability goes on cooldown after the 1 second global cooldown.
