Introduction
Hello and welcome to my very first guide! This guide is still a work in progress. I've played alot of games with Vi aready, but i'm still figuring her out. Here is my opinion on how you should build her, what runes you should take, masteries etc. If you have any suggestions, feel free to leave them in the comment section. I will read and answer all of them. All responses will be used for improving my guide.
And if u are going to play Vi, ALLWAYS play her with her own tune on the background!
This is essential for a good game of Vi :)
You can find and download ''Here comes Vi'' on ''https://soundcloud.com/search?q=vi''
Please leave a comment on why u downvoted this guide if u did so i can improve it :D
Pros / Cons
Pros
- Nice burst damage
- Great Chasing abilitie (
Vault Breaker)
- Strong champion overal
- If u pull of the full combo on a (preferably squishy) champion, u don't even give them the time to react before they are dead
- Anti-carry
- She looks awesome
- She comes with awesome music!
Cons
- You do need tanky items for her to actually get tanky
- CC is allways annoying, but that goes for almost every champion ^^
- Her laugh is kinda annoying
Abilities

INNATE: When Vi's activated abilities damage an enemy, she gains a shield equal to 10% of her maximum health for 3 seconds. Blast shield has a 18 / 13 / 8 second cooldown.
Ok, this is not a bad passive. A 10 % extra health is allways helpfull. You don't need to pay too much attention to this. It activates automatically.

FIRST CAST: Slows your movement speed by 15% while increasing damage and dash range over 1.25 seconds.
SECOND CAST: Vi dashes forward, dealing physical damage and applying Denting Blows to all enemies hit. Vi stops upon colliding with an enemy champion, knocking it back. Vault Breaker deals 75% damage to minions and monsters.
This ability is awesome. It gives you an amazing burst damage combined with
Excessive Force and it applies
Denting Blows. You can also use this ability to escape thight situations. Just make sure you don't hit someone on your way out cause that will stop your charge. Also be sure you won't be hit by any CC. That also causes you'r charge to cancel and it will go back on cooldown.

PASSIVE: Every 3rd attack on the same target deals additional physical damage equal to a percentage of the target's maximum health, reduces its armor by 20% and grants Vi bonus attack speed for 4 seconds. Denting Blows deals a maximum of 300 damage against minions and monsters.
This abiltiy is a passive. Take a point in
Denting Blows around level 3 and then max it last. Every ability and basic attack (Except her ult) applies a stack of
Denting Blows on the target. It looks a lot like
Vayne's
Silver Bolts only this ability gives you attack speed, and reduces their armor. Especially the attack speed is nice in battle. It will give you the boost you need.

ACTIVE: Causes Vi's next basic attack to deal bonus physical damage to the target and enemies behind it. Vi periodically charges a new punch and can hold up to 2 charges at once.
This is the ability you will be spamming in a fight. The important thing though is that you need to time it. If you activate it it resets you'r basic attack timer. So use it right after you basic attacked someone. When hitting an enemy champion or minion/monster with this ability, it creates a blast field which damages all enemies or minions/monsters behind it. This can be used for harrasing on a distance and for effective farming, but i'll get to the farming in a bit

ACTIVE: Vi targets an enemy champion and chases it down, knocking it up for 1.25 seconds, dealing physical damage. While charging, Vi is immune to crowd control and will knock aside enemies in her way, dealing 75% damage to them.
This ulti is awesome for immediately destroying the enemy carry. As soon as the teamfight starts, target their adc with your ultimate and follow up with
Excessive Force and if possible even escape with
Vault Breaker. Or if you are fed enough, destroy their whole team >:)
Items
Remember that this is still a work in progress. The items may change over time.
Mercury's Treads
Mercury's treads are mostly a must have on any bruiser. They dont only grant u movement speed, but also tenacity. This causes the duration of stuns, slows, taunts, fears, silences, blinds and immobilizes to be reduced by 35%. This comes in handy, cause CC is very annoying for Vi. Mostly cause it ruines your combo and causes your denting blows to reset.
Phage
Phage is a good item for early game. Health and damage. Do i need to say more? (and it also builds nicely in your frozen mallet or trinity force for late game)
The Brutalizer
This item is great on Vi. You completely destroy someones armor with it. Your denting blows go great with this. If u are able to pull your denting blows combo off, which causes their armor to be reduced by 20%, you reduce their armor with 30%. Plus this items gives you CDR which is always nice. Not only for your
Excessive Force so u can deal massive damage, but also your
Vault Breaker for chases.
Hexdrinker
Not my first item to build on Vi. I prefer
Phage and
The Brutalizer over this item, except when you are playing against ability power top champions like
Akali or
Vladimir etc. This item may also come on handy if the enemy team has lots of Magic damage.
The Black Cleaver
Kind of the same stats
The Brutalizer gives you, but improved.
you also get some extra health with this item. Not much to say about this.
Trinity Force
Nice item on Vi. Dont buy it as one of your first items. You should go for
Frozen Mallet and
The Black Cleaver first. Then go for trinity. After that
Zephyr is a nice choice.
The Bloodthirster
Nice item, but do not rush it. Go for some tankier items and then buy a bloodthirster to finish your build.
Maw of Malmortius
Same as hexdrinker, but then improved ;)
Zephyr
Very very very nice item for Vi. The attack speed, cooldown reduction, tenacity and movement speed are all great. All of those stats work great on Vi. You are gonna be amazed how high your attack speed is with this item and Denting blow's
Warmog's Armor
Health and Health regeneration. Allways a good thing to have. You can also take
Guardian Angel instead if
Warmog's Armor if you prefer so.
Frozen Mallet
Nice item on Vi, not only for the health, but also some Attack damage. Also usefull on Vi is the passive. You are gonna want that slow when chasing people. This enables you to constantly hit them in their back when they want to make a run for it.
Runic Bulwark
More of a tanky option. I would still prefer something with damage on it, but if u want to play the tank, go for it.
