Vi is a tanky bruiser who specializes at crushing all types of targets, with her percentage health damage and rapid engages. She also has one of the best engages in the entire game, as her Q Vault Breaker and ultimate allow her to close huge gaps and knock the enemy team aside to leap onto carries.

=======================================================================================================

The bread and butter summoner spell combination for winning lanes and wrecking faces. Flash Flashs quite nice on her because it allows you to guarantee you get your ultimate off on the target that you want dead, and is just pretty much the best summoner in the game for a wide variety of purposes. Ignite Ignite can be switched out on a case by case basis for Exhaust ExhaustI wouldn't take Exhaust Exhaust unless there was a heavy AD threat such as Wukong that your team seriously NEEDS to shut down.

Vi can be specced in a few different ways, but opting for the defensive tree will allow you to be that mid game bruiser/tank killer that you are striving for. 9/21/0 is the most optimal build path because you already get enough free damage from her W that you don't really need to spec into the offensive tree, but just like Lee Sin you can choose to go 21/9/0 if you are really intent on getting that extra juice into your abilities. Vi has to get down and dirty and be right in the middle of every fight so going for the CC reduction and added tank stats from the defensive tree will allow you to do just that.

Early Game

Vi is an incredibly potent brawler throughout the laning phase. She tends to do much better against melee champions top lane, so ideally you would want to pick her into something that isn't Vlad Vladimir/Teemo Teemo/Chogath Cho'Gath. Ranged Champions have the leisure of getting free harass on her 1-6 and due to the long wind up time of Vault breaker, people can often times just walk away when they see you charging it unless you are in a brush (which is a tactic you should try to take advantage of. A fully charged Vault Breaker out of a brush can clear a large gap and can often times surprise your laning opponent). Since we will be maxing E you will want to use that as your primary form of harassment, however be careful not to use it excessively, as it does tend to push the lane regardless of how you use it, so make sure you have proper ward coverage.

Post Level 6 Laning

At this point, you should have already decided how you want to play the lane out. If you are very fed and are doing extremely well, you might have a Brutalizer, or at least both Long Swords and boots at this point. Vi can do incredible damage with her full combo combined with additional E's to pretty much any champion. Try to use your ultimate at an opportune moment to disadvantage the enemy as much as possible, for example if you are laning against a Rumble or Riven, use it to dodge their ultimate and engage them for maximum effect. Vi is very strong after she gets 3 points in E so take advantage of this fact. Some matchups may be difficult so you may have to play safe until you get a few free E exchanges off on them to chunk them low enough. Often times you may be able to blow the enemys escapes or Flash cool downs with a well timed Q, which leaves them completely vulnerable to a free battering with your ultimate combo. In general use your head but try to get a feel for how much damage you can deal to the enemy and make sure to always get your third hit of W off whenever possible, otherwise you will end up losing most trades to most top laners as the steroid and increased damage is too much to pass up on.


If you feel relatively safe (know where jungle will go) and have placed your ward you started with, you can start chunking your enemy with carefully placed E's either on them, or even on the front melee creeps since the AOE cone stretches very far back to wither down your enemies health. Your Q is both your engage and disengage tool, so I tend to play it safer and reserve using my Q unless I am gauranteed a favorable trade, or I see or sense a Jungle gank coming, at which point you can simply Q towards your tower and escape from most situations.

Roaming to Mid

Once you have acquired your ultimate, you should utilize Vi's incredible roaming potential to the mid lane to try to make as much as an impact as possible. Due to the fact that most of your trades will innately push up your lane, the enemy team will think nothing of you constantly pushing out your lane to the enemy top laners tower, so you should take advantage of this certain scenario and as soon as you are finished trading, push out the lane and attempt to roam mid. Due to Vi's incredible gap closing potential with a blind fully charged Q out of the brush, if the enemy mid laner has not warded, you can guarantee kills on every single one of your ultimate cool downs (or at the very least blown summoner spells). This constant pressure will allow your team to apply more pressure throughout the map and help shut down the enemy team.

Team Fights
===============
In general, Vi will play the role of the initiator / front line. Her skill set makes her incredibly durable as well as very good at killing tanks (due to the ridiculous armor shred from W + BC) so having her peel for your AD carry is a very viable playstyle for Vi. Additionally, due to the diving nature of her ultimate, you can also utilize her to disable any enemy champion and easily take them out of the fight. Try to reserve your ultimate for their squishy AD/AP carry but use it at your discretion when the situation calls for a good knock up. Once you acquire a Frozen mallet, assuming your AD carry is very fed, you should sit on anyone that tries to damage them and simply peel them off with your Q+R. Vi can do very high damage to pretty much anyone so don't be afraid to hit a tank (assuming they are the best available target).

Tips and Tricks

Most walls can be cleared by charing up a full Vault Breaker and dashing through them.

In laning phase and team fights, utilize the AOE Cone that is behind your E, often times you may be able to poke someone out at max range by E'ing a melee creep in lane.

Assault and Battery(R) can be used to dash to enemies champions through walls.

You can close a distance of a fleeing champion by Q → Flash → Q → R

Assault and Battery (R) will place Vi behind your target. You can follow up with a quick Vault Breaker (Q) to knock them back into your teammates.

Boots of swiftness is very useful on Vi. Because it reduces the slow on Vault Breaker(Q) by 25%. Plus Relentless from the mastery tree can stack this effect. Making you move faster in Vault Breaker(Q) and being able to reduce the enemies time to react to your assault.

You can see that there's two kinds of masteries... Well with this other mastery added, it enhances the potential of Vi being solo... So, this is so called " Back-Up " mastery....

A summary of Vi... And hoping this helps fellow friends who enjoys Vi but just needs the right direction of using her to her max potential... A +rep will help me bring my day...
