Not saying Trinity Force is a bad item at all, just too expensive while giving useless stats (AP, crit chance) and having better alternatives.

I agree that Black Cleaver is not the "OH WOW SO OP PLS NERF SO GUD" item that everyone makes it to be, but the stats synergise well with Vi (CDR - check, health - check, ad - check, armor pen - nice bonus, armor reduc. - also nice). after 3 hits it gives a total of 35% armor REDUCTION (40% after 4 hits), that means that not only you are doing more damage, but your teammates as well (your ad carry specifically).
Also it doesn't stack additively but multiplicatively as far as i know (0,8 (20% reduc.) * 0,75 (25% reduction) = 0,6 (40% reduction)). I may be wrong though.

also the unique passive is not really important unless you stack it. It also does somewhat stack - it's just that the 4 stacks cap stays the same (if i recall correctly), so with 2 of them, 2 hits will apply 4 stacks, but 3 hits won't apply 6, but will cap it at 4.

NP, I usually do for people who got their stuff right and getting kind of trolled.

Trinity Force is not a bad item, but as I noted it's kind of wasted, so Frozen Mallet outclasses it, as for MS and speed Zephyr is a damn good choice with the highest speed bonuses, CDR and tenacity, and lets you go for any other boots. Ninja Tabi for example is pretty good on off-tanks, Boots of Swiftness is good too becouse Vault Breaker slows you down a bit, also makes Zephyr speed you more.

About Black Cleaver yea it's pretty good, but I think people really over estimate it (since it has unique passive now). Vi already has armor reduction, so it's not neccessary, with both effect on it's a 45% reduction, 8% penetration, +10 flat penetration, while a Last Whisper makes you have 20% reduction, 40% penetration. Last Whisper is cheaper too. Maths below in the spoiler.



In my opinion Vi's natural armor penetration with Denting Blows' HP% based attack is enough vs tanks, against carries and mages it's not that important to stack sh*t loads of it, so just stick to pure tankyness/speed/AD items. Also I don't like stacking based stuff.

Again, you think that I believe you should not take Denting Blows until level 13 or something.
No, i say take one point early (level 3) and leave it there. Rest I covered on the comment on your guide.
You just have 0 durability and you'll just be 2-shotted down, except if they are dumb enough to duel you 1v1 without CC.

Also, I didn't say Black Cleaver gimps her passive, I said not taking health like Frozen Mallet gimps her passive, and only health items you have are Trinity Force and Black Cleaver.

@ShortyHUN:
thanks for standing up for me. I appreciate it.
+rep.

Its 6/7/8/9/10% (+0.05% of total AD), that 4% difference at early levels when people tend to have less than 2k HP is nowhere as useful as Vault Breaker. Maths is the basic weakness of modern man... Vault Breaker stacks 1, you hit twice and it kicks in. Also leveling Vault Breaker adds 30 damage compared to 1% hp damage (around 10-20) every level, meanwhile lowering Vault Breaker CD, tell me how leveling Denting Blows benefits you early game.

As a solo top or jungler which Vi IS you don't go vs magic damage early game, thus using scaling MR better, even if just a little bit better, it's still better.

Yes Vi doesn't tanks so well becouse she's not a tank, but as off tank, 9/21/0 is nearly always better. In both cases the extra sustain helps more than that few extra that mostly helps high attack speed auto attack spammers, aka AD carries, making 9/21/0 the smart choice. Seriously look at her skills, it gives non-AD scaling damage, defense, escape, CC, armor reduction, etc... she is meant to be an off tank, yes she can be bursted, anything not ultimately tanky can be, but if she's AD carry, she becomes a big free kill sign.

Trinity Force is a good item, but it's for the skill spamming bursty champs, all her skills have relatively long CD making it pretty much wasted. Also the Sheen effect has 2s CD, so you would have to wait between 2 uses of Relentless Force which is pretty stupid, and after that you can't proc the effect for like 8s... all-in-all it's a bad choice for Vi. And don't forget, Trinity Force is damn freaking expensive.

+1 Rep for Crimson Dog for making sense and thinking stuff through, as people should.

I like how you down voted me just because of one build when I have a tank build, Crimson Dog. At least I made the effort to read your guide and try it. Also, please tell me how Black Cleaver gimps her passive? I just don't see it, as the CDR, AD, and armor pen all benefit her. Also, I talk about how to play Vi in the guide, how her attack speed/CDR/lifesteal offset the lack of resists. If anybody didn't read the guide before downvoting, you didn't.

I think you read that wrong. Here:

"Every 3rd attack on the same target deals an additional 6 / 7 / 8 / 9 / 10% (+ 0.05%) of the target's maximum health as physical damage, reduces its armor by 20% and grants you 30 / 35 / 40 / 45 / 50% attack speed for 4 seconds (max 300 damage vs. minions and monsters)."

Every third attack does an additional 6% + .05% of their maximum health, gives a 20% armor reduction and increases attack speed by 30%. At lvl 1. Please tell me how that's a negligible amount again, and shouldn't be leveled with Vault Breaker? Since, you know, Vault Breaker doesn't wait until the third hit to lay Denting Blows, it does it on the second cast.

Your scaling runes give you 1.35 magic resist at lvl 1. They only catch up to the Greater Glyph of Magic Resist at level 9, and the benefit of runes at that point starts falling off.

Also, Vault Breaker combined with Ghost or Flash is good at getting away. How you'd take serious damage along the way after bursting out is a mystery, unless somebody cuts off your exit. In that case, you over extended.

You masteries are garbage for Vi. She doesn't tank as well as the other bruisers. Her early game will be thrown off because she doesn't have the extra AD from her masteries to rely on. She may be a little tankier, but she won't have nearly as much early game damage. You can try building her tanky, but she has absolutely zero sustain in team fights with a tank build. If she gets bursted, it's still goodnight Vi, even with her Blast Shield. The smart choice is to build her CDR/AD/Lifesteal up and roll with a good support.

Take a bunch of health. Good idea, and Atma's Impaler will destroy you.

For runes, for a character that deals with primarily physical damage early game, AND gets magic resist along the way, the difference between scaling and flat magic resist runes is negligible (somewhere around 2% damage late game) and it's an even match around level 9. It's personal preference really.

As for Denting Blows, did you even read or calculate the benefits of it to Vault Breaker?
Vault Breaker just applies a stack of Denting Blows.
the benefit to leveling Denting Blows is 1% of the targets max health in damage and 5% attack speed after 2 more attacks, while each level of Vault Breaker gives you 60 more damage AND reduces it's cooldown by 2.5 seconds, making you much more mobile. Denting Blows scales off of enemy health and enemies have the most health late game, so it's most useful then. 1 point in it early is more than enough.
Vault Breaker in itself has awesome burst which people seem to underestimate.

As for Trinity Force, I build Frozen Mallet, so i don't get it, since the passives don't stack. Frozen Mallet gives a guaranteed slow, while Trinity Force gives a 1 in 4 chance to slow, which i feel is clunky. You also lose on a lot of health for your Blast Shield.
Only way i'd take out Frozen Mallet is if you put in another high-health item there like Warmog's Armor, but that costs even more.

Masteries are fine, as i build her like i would build olaf, riven or irelia - as a tanky ad bruiser, not an AD glass cannon. This build leaves me with more than enough AD at the end of the day and my Denting Blows and plethora of CC keeps me a threat whole game long, and the mastery tree is there to complement my role as a bruiser for soaking up more damage and for dueling. You are not the ad carry so you should not play as such.
Sure, if i get 21/9/0 masteries, i'd do more damage, but if i get caught, i'm dead with close to no chance to escape, and if i do somehow, i'd take very serious damage along the way.

Did you even try the build before downvoting, or even read it through?

The scaling magic resist runes need to be swapped for Greater Glyph of Magic Resist because runes are only good for early game. The benefits late game from a whopping 12 magic resist is so negligible, get the bonus early game.

You don't level Denting Blows until last on both ability sequences, leaving Vault Breaker underpowered the whole time. Read what Vault Breaker does again.

Wasting a slot for Boots of Swiftness and a Zephyr instead of building a Trinity Force leaves your final build underpowered.

Your masteries are just terrible, your AD is severely crippled.

ran the build work better then others so far i did skip the zyphr though and went for maw instead worked well

what are you talking about? are you sure you're on the right guide?
a) i have no jungle section, though, i may add one later on
b) i dont use zeal on Vi, ever.

your masteries on jungle dont add up and ive tried all the builds going with a zeal is not the right option gotta be a better way to start
