Hello, I'm Seymorbuttz and I'm going to tell you how to actually play Vi. A jungler I personally love! I'm just a pub scrub jungle with around 500 games exp. of just jungle. A lot of the guides I've read on Moba about Vi are just horrible, your a TANK!! build like it guys..

Pro:
Damage without building damage
Late game tank
Two gap closers
Fast clear times
Cons:
No built in slow
Passive has a long CD before lvl 11
Use of your Q will make or break you
Voice is annoying

YOU CAN Q THROUGH WALLS IDIOT ABUSE THE HELL OUT OF IT!!!! ABUSE IT

Standard jungle runes, I'm telling you guys get the movement speed quints they put you at 366 Ms without boots that's faster than most carries with T1 boots!!!. This makes chasing people and getting away when your counter jungling very easy.

Just pick your favorite AD tank masteries

Build everything up to the Avarice Blade in that order unless your going to Magic Resit boots which I don't build because they are the least cost effective. Build tank items mostly stacking health to buff your passive.

Wolves
Your Blue ask for a no smite leash, your lvl 2 grab E
Their Red
Gank
Take this path EVERY TIME unless they start red, your clear time is amazing if you get caught counter jungling just Q through a wall into a river, if they blow flash chasing you its worth it as long as you tell your team they blew flash.

If people like it maybe I'll make it a complete guide but that takes effort.
