Hi, my name is XMoogleX and I main Vi as a Jungle I also main as ADC/Supp. This guide will explain Vi's role what do in teamfights.

Vi is my favorite jung she is super aggressive very intimidating people will run from you if they see you. You can play with them with your ult Cease and Desist my favorite part about her.

An interesting article about Vi From Vision to Violence by DevBlog

Pros:

• Really good ganks
• A lot of kills after lvl 6
• Peels really good
• Her Vault Breaker is a good utility

Cons:

• Not the best team fight late game
• Vault Breaker can be dodged easily

I cant explain runes really but they are a big help

Max your Vault Breaker first it allows you to be bursty. Follow up with your Relentless Force a combo with Vault Breaker and Relentless Force is amazing does a lot of damage along with Denting Blows even more damage1!!!

This Shield is equal to 10% of her maximum health. And has a 18 seconds cooldown at lvl 1, 13 seconds at lvl 7 and 8 seconds at lvl 12.

Charges a powerful punch that carries you forward.

First Cast: Slows your movement speed by 15% while increasing damage and dash range over 1.25 seconds.

Second Cast: Dashes forward dealing 50 / 80 / 110 / 140 / 170 (+0.7) to 100 / 160 / 220 / 280 / 340 (+1.4) physical damage and applying Denting Blows to all enemies hit (deals 75% damage to minions and monsters). Stops upon colliding with an enemy champion, knocking it back. When interrupted, Vault Breaker goes on a 3 second cooldown, refunding 50% of the Mana cost.

It's used to gap close, jumps over walls, and interrupt abilities, and does a lot of damage. It does double damage when fully charged.

Every 3rd attack on the same target deals an additional 4 / 5.5 / 7 / 8.5 / 10% (+ 1% per 35 bonus AD) of the target's maximum Health as physical damage, reduces its Armor by 20% and grants Vi 30 / 35 / 40 / 45 / 50% Attack Speed for 4 seconds (max 300 damage vs. minions and monsters).

Shreds armor great for early game jungle clear.

Causes next basic attack to deal 5 / 20 / 35 / 50 / 65 (+0 .7 Attack Damage) (+0.7 Ability Power) physical damage to the target and enemies behind it.

Vi charges a new punch every 14 / 12.5 / 11 / 9.5 / 8 seconds and can hold 2 charges at once.

Excellent wave clear ability. Vault Breaker through a wave and Relentless Force can clear really fast.It can also be used to hurt enemies sitting behind a creep.

Targets an enemy champion and chases it down, knocking it up for 1.25 seconds,dealing 200 / 325 / 450 (+140% bonus AD) physical damage.

While charging you are immune to crowd control and will knock aside enemies in the way,dealing 75% damage to them.

Her ultimate is mostly what makes Vi so OP, and while casting, no forms of CC can affect her. However, abilities that cause an enemy to become invulnerable will disrupt it.

Some tips and tricks ive learned while playing Vi

You can Flash while charging your Vault Breaker.

Clicking on Thresh's Dark Passage while charging your Vault Breaker will put Vault Breaker on cool down. Don't worry only like 3 seconds.

Vault Breaker will hit targets just beyond the 'max distance' it shows you.

CC like Soraka's Infuse can put your Vault Breaker on cooldown but again its 3 seconds.

Use Relentless Force immediately after an auto attack to reset the auto attack.

Vi cannot be stopped by Amumu's Curse of the Sad Mummy.

The Sheen proc makes Excessive Force hit harder, allowing items like Trinity Force to make you hit pretty hard.

Cease and Desist does damage to people it knocks aside, so when going for multiple low health enemies who are fleeing, ulting the enemy furthest can sometimes result in easy double kills.
