Guide to Viktory

Today we'll be talking about a champion known as
Viktor, the Machine Herald

Without further ado, lets jump right into the abilities, his passive is Evolving Technology, which allows you to Augment one of Viktor's non-ultimate abilities for 1000 gold, his passive also gives you AP per level.
There are two main builds for Viktor, one is the Augment: Power build, which revolves around Viktor's Q, Power Transfer, and the Augment: Death build which focuses on Viktor's E, Death Ray.

Which should you choose?

By a long shot, the Augment: Death build, Viktor's E, Viktor's Death Ray is one of the highest non-ultimate abilities in the game.

Passive: Augment: Death

Q:
Use Q to last hit and harass, can also be used to save yourself when running due to the shield.

W: Viktor's W, Gravity Field, is a very strong ability when used properly, activate when chasing or running, in fact, the stun from Gravity Field can sometimes turn the tide of the engagement and you can actually kill the enemy when they are stunned!

E: Viktor's E, Death Ray is basically what he IS! This ability has huge burst and is Viktor's bread and butter ability. Learning how to land Viktor's death rays is crucial, at the same time however, it requires patience, play a lot against bots with Viktor to learn to land his E.

R: Viktor's ultimate, Chaos Storm is usually best used in teamfights where you can do a lot of damage, it can also be re-directed for 7 seconds when active, so be sure to take advantage of this and move it around when beneficial!
