Hello there! I'm not here to waste your time, I'm here to show you a new way to play Jax that is extremely strong against a team full of autoattack reliant champions and mostly just a fun build.

---

---

So without more waiting, lets get started!

Pros - 3 Second dodge tool - Amazing gapcloser - Usual TriForce+BoTRK combo making damage still good - RIP autoattack champions

Cons - Less health than typical build - Needs a lot of gold - Mages hurt on this guy a lot - Complains about not having a real weapon

Overview

Runes are fairly important on Jax as they will either let you succeed or fail in lane.

Overview

On 40% CDR Jax, there are two options. 9/21/0 and 21/9/0, however I strongly recommend the former as 9/21/0 makes sure you don't fall flat in lane if you mess up. Below are lengthy explanations for my reasons of taking certain mastery points.

Summarization

It doesn't matter what you take on Jax, just don't take anything in the Utility tree as it doesn't benefit Jax at all compared to the Offense and Defense trees

Overview

We always take our Empower first because it lets us deal the most damage, lets us win trades most of the time and the CDR per level on Empower has a bigger impact than Counter Strike or Leap Strike.

Why don't we max Leap Strike first?

Summarization

Finally, try new things and don't stick to a cookie cutter build. Try to build around the enemy team and if you're taking my 40% CDR route, then there are a good amount of CDR items that grant defense and offense which can be built around the enemy composition.

Prepare for a lengthy explanation:

Is it really? Think about it, Jax's strongest asset is his E in my opinion. When you think of Jax, you think of a hunchback with a lamppost dodging every autoattack you throw at him. You get to use your spells more without the fear of running out of mana due to a Frozen Heart. You can dump on nearly every autoattack champion in the game with such a small CD gapcloser and stun.

Sure you sacrifice health for 40% CDR, however if we do some simple maths we can see that CDR is very undervalued on Jax.

Ability (Max Level) - Without CDR - With CDR

Leap Strike - 6 - 3.6
Empower - 3 - 1.8
Counter Strike - 10 - 6
Master-At-Arms - 80 - 48

Q analysis:

We get a VERY small CD gapcloser, good luck running away from this Jax. This is also an escape, making Jax one mobile person. You can even take a Sightstone for maximum mobility if you get 5% CDR flat and 5% CDR Level 18 Glyphs. "Was that a Lee Sin or a Jax?"

W analysis:

We do more damage now, quicker autoattack reset, more magic damage. Using our Hybrid Pen runes, we do a lot of magic damage to squishies. Our W is the least benefitting spell/skill in our kit for 40% CDR, but it still makes a big change.

E analysis:

The biggest reason you would go 40% CDR. Lets see now; 6 second CD with 40% CDR, 2 seconds of it is used to dodge, 1 second for the stun. It has a 3 second CD in a melee duel with another champion. You take 25% less damage from AoE spells/skills as well, so AoE mages like Orianna can go cry in a corner.

R analysis:

Ever have that moment with Jax when you activate your ult to take reduced damage from a single autoattack? Don't fear, you have a 48 second CD on it now, so spam it as much as you want. Don't worry about "wasting" your ult anymore. We really have a 40 second CD on his ult if we count the 8 seconds that it is up. You can practically ult every minute.

Here is one of the areas our 40% CDR Jax shines. Fed ADCs can't keep you off their backs, you can peel too with your low CD stun (activate it early for a quicker stun.) Having more CC is never a bad thing now is it?

Your role in teamfights should be an AD Offtank, dealing a bit of damage while soaking a lot of it up. You're an Attack Speed reducing ( Frozen Heart), shielding ( Locket of the Iron Solari), stunning ( Counter Strike) tank.

Remember, you can always get a Zeke's Herald to increase your team's strength if it's mostly an AD composition. Black Cleaver while not the greatest item on Jax, can still help if you have a fed ADC like Lucian, Vayne or Caitlyn. Don't get it to support ADCs like Ezreal or Kog'Maw who do more than a bit of hybrid damage and generally don't give you anytime to activate your Black Cleaver stacks.

Also remember never to get caught out. Seriously. If you went the Sightstone mobility route, make sure to ward deep and to web your own jungle so you can do your amazing Lee Sin Jax 40% CDR wardjumps. Your team should be very happy about it (especially your support.)

• You can wardjump with Jax's Leap Strike, and it isn't limited to wards too! You can leap to Teemo's Noxious Trap, Shaco's Jack In The Box, Jarvan IV's Demacian Standard, and Thresh's Dark Passage! Anything you can click on aside from turrets should let you Leap Strike to it.
• To activate your 3rd strike faster, do a reset on the autoattack before the 3rd strike. Combining your Empower with your Master-At-Arms passive, giving you amazing AP burst. It's a more advanced technique, but if you're fed you can burst quite hard with it.
• If losing lane, don't rush Trinity Force or Blade of the Ruined King because rushing damage while losing lane is never a good idea. Go for Warden's Mail when up against heavy AD champions like Tryndamere or Spectre's Cowl/ Negatron Cloak when up against heavy AP champions like Ryze. Remember to hug your tower too! Try to adjust your build around the enemy composition.
