So why should you follow my build? Let me explain why this build can carry you from Bronze to Challenger as they say it. I've been using this build on Vi ever since preseason 6 was up, and I have to say that it's pretty strong. I was 0/6/3 the first 10 minutes and at the end of the game I somehow got 11/8/24. This build can help you bounce back from a losing game and claim that nexus. This build is still in progress and more explanation is to come.

Spells

Smite and Flash is pretty much my go-to spells for jungling, smite is basically a must have for every jungler and flash is very useful especially when chasing oponents. Ghost is not recommended but you can use it when charging q to get closer to the enemy faster.

Runes

Armor penetrating reds work well with Vi's Denting Blows, armor yellows give you that extra sustain when ganking/dueling, blue magic resist is to sustain against mages/AP assassins and AD quints are for extra attack damage. Yep, pretty staright forward.

Masteries

Why Deathfire Touch? It's because it will deal extra AD for your abilities.
