Early in life, Viktor discovered his passion for science and invention, particularly in the field of mechanical automation. He attended Zaun's prestigious College of Techmaturgy and led the team that constructed Blitzcrank – a scientific breakthrough that he expected to vault him to the top of his profession. Unfortunately his triumph was usurped by Professor Stanwick, who stole credit for developing Blitzcrank's sentience and later used Viktor's research to revive Urgot. Viktor's appeals for justice fell on deaf ears, and he sank into a deep depression. He withdrew from the College and barricaded himself in his private laboratory, cutting all human ties. There, in secret, he conceived a project for which nobody else could claim credit. Desiring both to revolutionize his field and to eliminate the jealous human emotions which festered inside him, he engineered parts to replace and improve his own body.

When Viktor re-emerged, almost no trace of the original man remained. Not only had he supplanted the majority of his anatomy, but his personality had changed. His previous hope to better society was replaced by an obsession with what he called ''the glorious evolution.'' He saw himself as the patron and pioneer of Valoran's future – a future in which man would renounce his flesh in favor of superior hextech augmentations. Though Viktor's initial appeals were met with heavy skepticism, scientists were confounded by the sophistication of his machinery. By integrating his mind with techmaturgical devices, he had been able to drastically accelerate the progress of his research. His transformation had stripped him of what he perceived as his emotional weaknesses, but there was some lingering residue of resentment against the Professor. Viktor joined the League of Legends to pit his inventions against the greatest opponents Valoran could offer, and to correct any weaknesses or inefficiencies that remained.

''In one's hand, techmaturgy is a tool. As one's hand, it is liberation.''

Viktor is the new hero on the block, so i dont pretend to know anything, but this build works for me and its about time i made a guide.

Firstly i think Viktor is already quite underrated, many of the people i play with think he sucks, But i have found some success with him. I'm not usually highest on the score board, but usually have one of the Best K/D ratio's. That said i think he is in need of a slight buff (I also think Ahri needs a nerf though)

Viktor can fill many rolls, I've primarily played him as a mid, but this build will work when sharing a lane as well.

Pro's
Amazing poke in the form of his Hextech Ray
Not too squishy and can deal a fair amount of damage
He fires ******** lasers!
Basically a robot.

Con's
Early game can be hairy.
Laser is quite thin and quite easy to dodge.
He made Blitzcrank

Okay rune wise i need a little work as I have only just completed my first generic set of runes.

I go for Greater Mark of Ability Power's as it makes you a little more scary at game start. Your Death ray will hit for a little more and keep your enemies a little weary. When solo mid it can easily cause your opponent to play it more defensive, but your laser out ranges turrets when used right so Poke away.

Greater Seal of Scaling Mana Regeneration are amazingly useful for me as i always find myself lacking Mana. These greatly improve my ability to stay in lane.

Greater Glyph of Scaling Cooldown Reduction. I like to fire a lot of lasers at my enemy. Continuously poking away at my foe until they die, or retreat.

Due to the generic nature of the runes i have, i use Greater Quintessence of Experience. These usually let me take the lead when solo mid and hit level 18 much quicker.

Masteries are 19/0/11 aiming for Ability power and Spell vamp to enhance the sustain. Transmutation + Hextech Ray is by far awesome. If you think Ahri's Life steal is annoying, watch a Viktor firing off Death Lasers every 8 seconds and gaining health from everything it hits.

Item Purchases, as everybody should know are pretty unique to each player. Sure finding the top guide for your favourite champion might seem like a good idea, But it might not fit your play style. As such this build suits my play style, and it might not suit your or countless others.

I start the game with a Meki Pendant this give me a boost in my early game sustain, especially if you fire your laser as much as i do. I usually accompany this with a Health Potion or Sight ward often both if sharing a lane. Once i have farmed up about 800 gold I focus on upgrading the Meki Pendant into a Chalice of Harmony and adding Boots to my arsenal. Now i move a little faster and am able to stay in lane much longer, not to mention a slight (but noticeable) resistance to other magic users, but because the Mana regen from the Chalice of Harmony regenerates more when your low on mana your ability to burst an enemy down is reduced.

Upgrading the Boots to Ionian Boots of Lucidity is next on the agenda, you will need 700 gold for this i usually wait for 1200 to purchase an Amplifying Tome to provide an AP boost.

Hextech Revolver is the next item i get, either built straight (1200 gold) from acquired gold, or upgraded (765 gold) from the Amplifying Tome you may have got last trip. Soon after upgrade this into a Will of the Ancients.

This is traditionally when i upgrade Viktor's Augment. I generally favour Augment:Death for the additional AP which boosts your damage output and the DoT that Hextech Ray now provides.

rabadon's deathcap] is a must at this stage, purchase the [[needlessly large rod first if you can't get the cap instantly.

The final item choice varies between games. I most often purhcase Zhonya's Hourglass for the additional AP and 2 second safety button. In a game of heavy hitters a Force of Nature might be a good choice or a Void Staff if against a team with heavy magic defence.

rylai's crystal sceptre is also a good choice especially when paired with Hextech Ray.

Late game it might be a good idea to drop the Chalice of Harmony as your mana/mana regen should be high enough to keep you going.
Some recommendations:
Deathfire Grasp Good for team fights when something has a silly amount of health, Provides a little more MP5 and a noticeable amount of ability power.
Moonflair Spellblade Extra AP and tenacity, useful if your opponents have a lot of CC
Void Staff For those games when magic resist is all over the place.

Remember though, these are just my suggestions, each game is as different as each player so try to adapt to the situation at hand.

Freaking laser beams! That's why i bought Viktor.

Hextech Ray
Death ray is a skill shot that requires you to click a start point and drag in the direction you wish the laser to go. Honestly this was the first time i had encountered this type of skill shot and my first use of it went completely wrong.
Hextech Ray deals 70 / 115 / 160 / 205 / 250 magic damage + 70% ability power at the respective levels. This is your main damage dealer, it can shred minions and deal a high level of damage to many heroes when aimed right.
Its cool downs are pretty short to 13 / 12 / 11 / 10 / 9 seconds at each level this si further reduced by the Ionian Boots of Lucidity and Greater Quintessence of Experience if taken. Once upgraded with Augment:death Hextech Ray will deal and additional 40% magic damage over four seconds, useful when chasing or trying to kill a Tryndamere using Undying Rage

Power Transfer is my second skill choice and a max this as my secondary skill.
This is a targetted ability that deals 80 / 125 / 170 / 215 / 260 magic damage + 65% Ability Power it also converts 40% of the damage dealt into a shield that protects viktor. I can not tell you how awesome this can be. the amount of times i have used it on a minion or the jungle to save me from an Ignite, poison or Karthus ulti is pretty high.
Power Transfer is on a slightly shorter cool down of 9 / 8 / 7 / 6 / 5 seconds. It serves as a good last hit if your chasing a hero down or trying to steal a kill, generally i use it at the start and end of combat to ensure i can fight longer and flee from pursuers.

Gravity Field is an area of effect slow/stun. Whilst within the boundaries of the ability Minions and champions are slowed by 28 / 32 / 36 / 40 / 44 % Every 0.5 seconds they gain a stack, once it hits 3 stacks those within are stunned for 1.5 seconds.
it has a cool down of 17 / 16 / 15 / 14 / 13 seconds and i generally use this at the start and end of battles. It makes a great initiation as enemies either have to walk around, often splitting up, or run through and get stunned. It also prevents people from chasing you and is wide enough to block most paths within the jungle.
The stun of Gravity Field has the often amusing effect of freezing animations for its durations which can be quite comical at times.

Viktor's ultimate is Arcane Storm this is an are of effect that spawns at a targeted location, continual clicks of R allows the player to guide the storm around, moving faster the closer it is to Viktor
Upon cast it silences champions for 0.5 seconds and deals 150 / 250 / 350 magic damage + 55% ability power damage dealing 40 / 60 / 80 magic damage + 20% Ability power each second to those within its area of effect.

Flash and Ignite are always my choice of summoner skills. Combining Flash with Gravity Field almost guarantees escape. Whilst Ignite plus an Augment:death enhanced Hextech Ray usually ensures an enemies death.

Other choices could include Clairvoyance I've tried playing Viktor as a support and it is not great in my opinion. If tried max Gravity Field first followed by Hextech Ray.

Clarity If you have mana issues, but hopefully if you follow this guide a little that won't be too much of an issue

Give Viktor a try and judge for yourself. His Hextech Ray is an amazing poke and i just love seeing it fly across a lane. There's not really much i can say for, or against him this early in his life to be honest. If your ever fighting a Viktor do not under estimate the range of his Hextech Ray he can safely hit you whilst your hiding behind your turret

If you've taken the time to read down to hear then congrats on reading my first ever guide, i would appreciate feedback from veteran guide makers and other Viktor players, But be nice and enjoy the game :)
