[11.19] Vex Build Guide

By Kaofan
Welcome to the METAsrc statistical Vex build guide, Top Lane 11.19. We have calculated the highest win rate item build, best runes for Vex, mythic items, skill order, full item build, starting items, summoner spells, item build order, trinkets, and counters. METAsrc Champion Build Guides for League of Legends are based on statistical analysis of the latest match data, so you can trust that our stats are unbiased and always up to date.
Hi guys! I am Kaofan, and this is my guide to Vex. This is my second guide here, and I am very open to advise, tips or just any comments at all. Vex is the latest addition to the rift, so of course no one has a lot of experience on her yet. As a consequence of this, the runes, items and that kind of things are still a bit uncertain, so maybe these things are not perfect yet, but I try to keep this guide as up-to-date as possible.
Who is Vex?
Vex is a mage, who will likely be played mostly on Mid, but perhaps she can be useful on Top or Support, but this guide focuses on her in the Midlane. She mainly has burst damage, on a very high range. Her passive might feel a bit similar of Annie's, while her ranged abilities might remind you of Xerath or Lux. I think she is a very versatile champion, as she will have some decent AoE poke, but also a good all-in potential with her R and W. She will likely be a good counterpick against dashing champions, but also a very viable blind pick.
Doom 'n Gloom Vex (Passive)

Range: 1600
Cooldown: 25 / 22 / 19 / 16
Periodically, Vex gains Doom, which causes her next basic ability to knock down and fear affected enemies for 0.75 / 1 / 1.25 / 1.5 seconds (depending on level), during which they are slowed by 60−99% (depending on initial distance from Vex). Doom's cooldown resets upon respawning.

Nearby enemy champions that dash or blink, as well as targets hit by Looming Darkness, will be marked with Gloom for 6 seconds. Vex's next basic attack, which becomes non-projectile, Mistral Bolt, or Personal Space against a marked target will consume the mark to deal 30−180 (+25% of ability power) bonus magic damage (depending on level) and refund 25% of Doom's cooldown.

Against marked non-champions, Gloom deals 40 / 45 / 50 / 55 / 60% damage (depending on level) and refunds 10% of Doom's cooldown.

Mistral Bolt Vex (Q)

Range: 1200
Cooldown: 9 / 8 / 7 / 6 / 5 Cost: 45 / 50 / 55 / 60 / 65
Vex unleashes a wave of mist in the target direction, dealing 60 / 110 / 160 / 210 / 260 (+60% of ability power) magic damage to enemies it passes through and accelerating in speed though reducing in width after travelling 500 units.
Personal Space Vex (W)

Range: 475 / 550
Cooldown: 20 / 18 / 16 / 14 / 12 Cost: 75
Vex emits a shockwave around her before the cast time, gaining a 50 / 80 / 110 / 140 / 170 (+80% of ability power) shield for 2.5 seconds and dealing 80 / 120 / 160 / 200 / 240 (+30% of ability power) magic damage to all nearby enemies.
Looming Darkness Vex (E)

Range: 800
Cooldown: 13 Cost: 70 / 80 / 90 / 100 / 110
Vex commands Shadow to fly to the target location, increasing the radius of the area as it travels. Upon arrival, Shadow deals 50 / 70 / 90 / 110 / 130 (+40 / 45 / 50 / 55 / 60% of ability power) magic damage to all nearby enemies and slows them for 30 / 35 / 40 / 45 / 50% for 2 seconds.

Looming Darkness will cast at max range if cast beyond it.
Shadow Surge Vex (R)

Range: 2000 / 2500 / 3000
Cooldown: 140 / 120 / 100 Cost: 100
Vex commands Shadow to launch itself in the target direction, granting sight of the area along its path for 0.4 seconds each and dealing 75 / 125 / 175 (+20% of ability power) magic damage to all enemies hit.

Shadow stops upon colliding with an enemy champion, marking them for 4 seconds and revealing them for the duration. Shadow Surge can be recast while the target is marked.

RECAST: Vex commands Shadow to pull her towards the marked target with displacement immunity, upon arrival consuming the mark and dealing them 150 / 250 / 350 (+50% of ability power) magic damage.

If the marked target dies within 6 seconds of being hit by Shadow Surge, Vex can cast Shadow Surge again at no additional cost for the next 12 seconds after 0.5 seconds.
Pros and Cons - Support
Good Poke- As Vex you have great poke with your massive *** abilities and being able to hit people from virtually anywhere within reason. She pairs nicely with ADCs that have CC in their kits or that can take advantage of that CC like Ashe and Kai'Sa. She's a great poke support and has a variety of keystones that can make her a menace in the support role.

Good Early Game- Vex having such high base damage in her kit makes her a powerhouse in the early game, and can take great advantage of that with her fear as it allows for hit and run strats to burst your opponent down over time. It can be even better in the support role where everyone is squishy.

Good at protecting ADC- Vex is an anti-assassin mage. Her kit allowing her to cancel dashes means you can guard your ADC against assassins a lot better than most supports. you're essentially your ADCs safety bubble and anyone who tries to get near it gets popped. You can also follow in on fights to stay with the ADCs that want to be in the middle of the fight like Draven, Lucian, and Kai'Sa.

No Mobility- Against certain matchups there's a good chance you can get locked down if you're not positioned properly by champions like Nautilus, Braum, and Zyra who have easy to activate hard CC. Do your best to stay away from heavy CC champions and poke them out of lane instead.

Slower Power Scaling- As a support you're naturally going to have less power than mid up until you get to around mid game and start getting into your Lich Bane and Cosmic Drive. Up until that point, you'll be more valuable for your fear and empowering from Imperial Mandate.
Pros and Cons - Mid
Big Abilities - Your abilities as Vex are relatively easy to hit as most of them are large AOE spells that take up a solid chunk of lane. With that in mind, every hit with an ability will apply some form of DOT whether that's just Liandry's or Liandry's + Demonic.

High Base Damage- Vex has some really nice base damage(ignore E) and that makes her a more forgiving champion early game, as she has low scalings for the most part and like most champions, doesn't have much power before mythic. This will give you time to get mythic while still being able to bend over anyone that challenges you, aside from a few counters.

Low Early Game Mana Costs- One thing that I picked up when I first looked at her through those early clips sent to league youtubers was that her mana costs were pretty high. Luckily, her Q and E have scaling mana costs which are great as it allows for more ability spam without requiring Seraphs or Tear. Just a simple Manaflow band should be enough to keep your mana in check until you get Liandry's Anguish.

No Mobility- You have no mobility with Vex's kit and that can be a problem since your 2nd cast on R throws you directly into the fight, meaning there's a higher chance that if you let the fight go on longer than a few seconds you will get your *** beat. It also makes it harder to get away from champions that can lock you down like Morgana, Thresh, and Malzahar.

High Mid Game Mana Costs- Since Vex has scaling mana costs on Q and E the amount of resources you'll be using up as the game goes on will naturally increase. At max rank Q costs 20 more mana than 1st rank, and max rank E costs 40 more mana than 1st rank. It won't be a game changing issue due to you getting Liandry's and stacking mana runes, but it's something to be wary of in the case that you've been playing aggressively the entire match.

Weak Early CSing- For some people who aren't accustomed to farming with low AD champions like Vex, Ryze, and Lissandra, farming may be challenging due to the precision needed for last hitting. Vex curbs that a little with her Q being a good wave clear tool, but it's best not to spam too much with it as it will drain your mana fast. Once you get Liandry's you can be more liberal with your usage but until then it's best to get used to last hitting.
