Nice item build for her, I like the Mercury's Treads. I'd put the skills from Durability and Veteran's Scars into Tough Skin and Bladed Armor though since it'll help you clear the jungle camps faster. Also Summoner's Resolve will get you gold faster too.

As for her first ability, you should get Vault Breaker or Relentless Force. Reason is if you get invaded Vault Breaker will help you escape, while Relentless Force can melt blue along with Smite and when your done you're lvl 2. Voila, you now have Vault Breaker too.

With a good leash blue buff shouldn't cost you more than one pot, it's a better choice than wolves imho. I take blue first usually and I'm usually done with red before I have to b.

I'd like to see some tactics added in, how to move her through the jungle and such. Other than that, good guide. I'll give you a vote up, check out my build and comment please!

True, she may indeed benefit, just as Lee Sin could benefit from AS. However both of them I play like both bruisers and AD casters. So I would rather have raw damage to burst with on each of my skills and AA rather than get more AS for hits from Denting Blows and Lethality . The attack timer reset on Relentless Force allows for 4 rapid AA in quick succession. Followed up by your Q, and auto attacks before and after, this lets you easily max out the stacks of BC and dealing tons of physical damage at every step in your combo. I do see crit chance attractive for the sole reason of 4 burst attacks through Relentless Force. If you don't mind britishpleasure, feel free to overlook my guide Comprehnsive guide to Fisting and the human response, and see what you think, you may even find some information there that you find useful. Of course all votes are appreciated and if you wanted to talk league via PM I usually check in once a day.

Thank you for your comments and help, I am really working hard on my guide and I updated a lot of information thanks to you and everyone's comments.

Also please allow me to explain a few things about the issues you brought up. I personally feel that Vi is an amazing with crit because of both the armor reduction that comes from Black Cleaver and the third stack of Denting Blows. I had crits that hit for over 1k damage and for that reason I feel it is nothing to turn your head to. Also Denting Blows increases your attack speed and Lethality has double the effect on melee so I believe she can benefit from it.

Also keep in mind you aren't a Crit Champion, so some of your mastery points are waisted. I use the defensive tree. Try out Spirit of the Ancient Golem over wriggles. I find it farm more effective

I would opt for more AD. You are very survivable with this build but have done very little to increase the attraction of her extremely High ratios (up to 1.4 on her Q alone). I would opt for a more offensive option that helps survivability through Lifesteal. Ravenous Hydra perhaps?

Thank you! Believe me i've been trying to fix that space issue, I think it may be a glitch but i'll keep trying. You'll be seeing a lot of changes that will offer more info about jungling with Vi so look forward to that.

Thank you so much for your comment and allow me to explain a few things about what you said. You say the points in Lethality and Frenzy are wasted because of no item in the standard build that gives crit chance but the Trinity Force does give crit chance since it is built off a Zeal. Also if you may have noticed every item on here makes her tanky in some way so you'll never see an Infinity Edge on here.

About the runes i'll definitely look into adding more options. This guide is no where near complete and its really more of a base for people looking for a quick build so they can jump into the jungle, well at least right now that is. Also this is meant to be completely about the jungle, ganking, and doing your best to help you team dominate their lanes, so i'm trying to find what best for that.

Thank you for telling me why you feel this guide isn't up to par with other ones. Its nice to know why i'm getting down voted. I'll be updating this guide often so please look forward to that.

Just some things that I noticed that may help making your guide better.

Mastery:
Based on your item build, there's no crit items in there so points in Lethality and Frenzy are wasted, suggest that you add the 3 points into Sorcery instead.
Another one is Summoner's Resolve since you take Smite but it's personal preference.

Runes:
Alternative runes like Greater Mark of Attack Speed, Greater Glyph of Scaling Magic Resist and Greater Quintessence of Movement Speed can be suggested.

Overall, I like your build so keep up the good work!

Except that these is no space between the pros and cons, this guide looks veeeery good :D

+1 for you ser
