Viego is one of the most unique champs in league and it makes alot fun to play him. He hase a very unusual playstyle and provides even with a on paper simple kit many different mechanics. Another thing that makes him different from many other champs is that he can be played on every role (some more sucessful than others but overall playable everywhere).

Pros

-Potential to carry entry teamfights
-Many different builds possible denpending on your playstyle
-Unique Kit
-Every game feels different because of the possesion mechanic
-Big outplay potential
-Easy to play hard to master
-Always usefull no matter what
-Insane sustain


Cons

-Hard to learn teamfighting
-The need of basic knowledge from champions
-Depends on his team
-Easy to mess up plays by getting to greedy
-Lee sin syndrom (more to that in the tipps)

(P)Sovereign's Domination
This is viegos possesion mechanic. When he starts possesing he gets untargetable (except towers), hp back, blinks to the location of the dead body, replaces Viego's basic attacks, basic abilities, items, base stats (based on Viego's level) with the posses champions one. The free charge of his ult has a 1,5 second cooldown and he gets 10% bonus movement speed toward enemy champions. Something that you should keep in mind is that it is not always optimal to take the dead body of someone (see the lee sin syndrome in the tipps) and even if you don´t take it right after the kill you have 8 seconds to still take it. Keep in mind that you take every bonus effect back with you even if you leave the body (tristana q, malphite passive, galio w passive ect).

(Q)Blade of the Ruined King
His main damage tool and one of the strongest passives in the game. You can use your q passive to cancel the q animation (more info in the tipps).

(W)Spectral Maw
This spell you will either use to gap close or to dodge enemy spells. It is hard to hit at the start but you will get used to it.

(E)Harrowed Path
Probaly the hardest ability to use right (atleast as lane viego). Most of the times used to reposition yourself or to chase enemys. It can be to used to trade enemys by using it in the minion wave running to the enemy w-aa-q-aa and run with the e in safty if he chases you q him again and he should be now be forced to get away from the minions if he didn´t already done it at the start. Overall a really great tool to reset the minion aggro. If you use your W while in your E you get visible for a short time but you get invisible shortly after. You can use it by starting channeling out of vision and than goin to the enemys. Otherwise you can to start to channel your w and insta use your e to get a almost none visible w from the start (more to that in the tipps).

(R)Heartbreaker
His main finishing and escape tool. In the early you can finish off enemys that have around 200 hp while in the late you can kill them when they have around 1/4 of their hp. Do not be afraid to use your ult to escape because i usually use it around 2-3 times every game to escape.

1) The classic lee sin syndrom is something that you need to get rid if you want to get good as viego. What i mean by that is to insta click always on the dead bodys of people after killing them to posses. You need to learn when you can take someone and when not to because if you take for example nami while 3 people focusing you you insta die. You can almost always take over tanks after killing them but keep in mind that you atleast need to be 1,5 second them so it is possible that it will lower alot your overall dps if you take them over. Just try to see in your gameplay when it killed you to take over champs that way you will learn it very fast.

2)When you use your w in your e you get visible for a short moment but after that you get invisible again. Use it when your out of vision and get near your target to suprise stun them. Play Video

3)You can use your W than your E to suprise your enemys because they can´t see your W animation that way. You can overall use your e in every animation Q and even R to chase faster your enemys. Play Video Play Video

4)You can cancel your Q animation by using it while doing a Q passive auto atack. Play Video

5)Your ult can get further if you use it over big walls. Play Video


6)You can use your E to zone your enemy away from the minions because if he walks up to your E you combo him and get out of the trade without that he can trade back.

7)Playing him in teamfights is the hardest part about him. The way i recommend you playing him is like you would play a kha´zix you wait until the teamfight starts and not go in before 2 or more guys of your team are in the fight because that way they use the key spells on them and the enemys get low life and you only need to finish them off. I to often try to stay in that time frame in my shroud (e) and sometimes even run around the jungle just to get a new position. Always try not to get foccused and if you get hard focus and you can´t finish someone off just back out with w/flash or ult. Play Video

8) Use your E when you pushing towers on the walls near the tower and not on the tower that way you can always escape even if you get ganked while pushing.

Early game:
There are some basic concepts to trade as viego. First you always (if possible) want to Q the enemy champion and minions at the same time because that way you can heal up on the minions and atack the enemy if he wants to stop you. Anohter thing you should try is to Q the enemy always when he wants to go for cs (the best moment is when he starts his auto atack animation or shortly before that). Your w spells is not only a stun but to a dash that you can use to dodge spells from poke champs or to get out of key spells from enemys (Cho Q, Jax e ect.). If your enemy don´t have their key spells up, don´t have overall good long trades or you are still healthy enough you can go for your short trade combo: W-AA-Q-AA but you can already cast your Q when you start the animation from the auto atack that way the Q animation gets canceled. After that you always want to kite back (auto atack if he chase if not just run). If the enemy has his key spells than you should only Q poke and if he walks up to much Q-aa. The most importent thing you should keep in mind even if you lost more hp than the enemy in the trade you can still heal it back up without much problem. Your all in combo would be w-aa-q-aa-e(if you didn´t used it to chase at the start and try to fight in your e while chasing him) and finish him off with ult if he hase around 200 hp.

Mid/Late:
You mostly want to teamfight as viego. You should always keep your sidlines pushed and than looking to teamfight. In teamfights you play it like in tipp 7 said and/or try to get a good flank if possible. In objective fights you almost everytime want to use your E on the walls of the dragon/baron and get that way a big shroud where you can move freely. The main target to focus for you in fights are hypercarrys (if they are feed) or the frontline if you have good hypercarrys but you should always have in mind that you normaly never want to take over 5 seconds (most time not even 3) to kill your target. If you think you will take longer than that you should focus someone else. Play Video
