Pure power armor shredder
Not Updated For Current Season
Do not finish your jungle item. You will get max cdr from BC and TF plus damage coming from armor reduction and utility - AS and move speed. Health stats on these items will keep you alive through mid game. BC + TF is a perfect item combo for Vi since both of them synergy with her skills and passive. Duskblade gives her the assassiny feeling and is a massive burst in damage. If you feel overwhelmed - you can exchange it for a defensive item - my recomend is Sterak's Lady Gaga. You can also morph jng item into cinderhulk and buy dedicated boots. This will make you more tanky but after few games you'll notice it is not needed since Vi is already durable and healthy in team fights.
Boots of swiftness reduce her Q slow during charge, making her ideal for pursuits.
Main combo is Q, atack, E, R, E
This is a perfect execution, but you can make the Es faster if the enemy is jumpy.
Other way to execute this is R, E, fast Q, atack, E
