Jax - The Grandmaster at Arms (Lore)

It is seldom the case where a champion is defined by his actions after joining the League of Legends rather than before. Such is the case with Jax, for whom the argument could be made that he is the most prolific tournament fighter currently at the Institute of War. Before joining the League, Jax was an unremarkable soldier-for-hire. For reasons known only to the former leader of the League, High Councilor Reginald Ashram, Jax was put on the top of the list of candidates to receive a League Judgment - the interview process that either accepts or rejects a prospective champion. His Judgment was the quickest in League history, where the Doors of Acceptance glowed and slowly swung open as soon as it began. Jax faced no recorded Observation or Reflection during his Judgment.
Jax proved himself to be an immediate terror in the Fields of Justice. The self-proclaimed Armsmaster of the League rattled off a streak of consecutive wins that to this day has not been matched. A number of summoners in the League grew concerned that the perceived objectivity of the League of Legends would be questioned by the presence of an unknown fighter who was unbeatable. For this reason, the new leader of the League (following Reginald Ashram's disappearance), High Councilor Heyward Relivash, created special restrictions for Jax to fight under. This was something the League had never done before, and something which has never been done since. The burly fighter responded by imposing his own special conditions; as a means of protest, he permitted himself to fight using only a brass lamppost. Neither the League's sanctions nor his own has affected his winning ways. The League has since rescinded its sanctions, but Jax has not; he fights and fights well with his trusty brass lamppost.
"Be advised - there has been an outbreak of lamppost-shaped bruises in the League of Legends."

Summoner Spells

Great Summoner Spells

Ignite for that "just in case" or "you never know" moment and which you want to secure that kill

Flash don't think I really need to get deep into why you need flash...but if I have too. Flash is great for any champion. It gets you to close that gap to no kill to that first blood. Also for running away or juking the enemy and so you don't give them a kill.

Jax - Skills

Passive - Relentless Assault This is his passive. His passive op. 'nough said...Just kidding. No but really. This passive is great with the composition of skills he has. His ult Grandmaster's Might because of the ult's passive. Empower because this skill counts towards the passive. All in all a great passive for the mighty Jax

Q - Leap Strike This skill is just like katarinas Shunpo where you can jump to a friendly champion or ward and of course, enemy champions. This is a great skill with many uses. To close gap or to run away. To initiate or to lure in a greedy summoner. If scales with AP AND AD.

W - Empower This skill is your main skill for damage output. It counts as a hit towards your passive Relentless Assault. It scales awesomely (if that's a word) with its AP ratio. 60% of your AP. Doesn't seem like much? but think about it. First off people dont see the fact that you can add that on with your Leap Strike (which that skill scales with AP AND AD) and add that with Sheen. So you do the math...cause I don't really want to.

E - Counter Strike The best skill out there...well I think. "For up to 2 seconds, Jax dodges all basic attacks and takes 25% less damage from area of effect abilities. At the end of the duration or if Counter Strike is activated again, Jax deals physical damage and stuns nearby enemies for 1 second. This spell deals 20% additional damage for each attack dodged to a maximum of 100% increased damage." Does that not sound OP enough to you? This skill scales only with AD but your physical damage scales at 0.5. BUT...BUT your additional damage scales 1.0. Add that with a bit of Empower and you are set.

R - Grandmaster's Might This is a tricky ult. The ult passive is great and awesome with your Relentless Assault Cause every three skrikes deals additional magic damage. 0.7 PER AP. This passive will own your enemies, expecially if you have Guinsoo's Rageblade. But the active is the tricky part. Your active gives you bonus armor and magic resist for 8 seconds. The bonus armor scales with how much AD you have. 0.3. The magic resist scales with how much AP you have. 0.2. I'm still getting the hang of when to use it. But my best guess, is to use it before a team fight. Actually use it if you are taking some heavy damage. Because I have used it before and I barely got touched and then later on I get killed when I could have saved it and got away. I think this skill just has to be activated when you really think you need it. Like a involuntary action. Well for me atleast for me.

Jax - Items

There are notes at the items but not as thoroughly explained as here.

Spawn Item Options

So for your first items you can get
Boots of Speed with three Health Potion
Doran's Shield
Long Sword with three Health Potion

Why Boots and Pots

Typical standard items for top lane. Its good for the runes and masteries that I have picked.

Why Doran's shield

It has that good cheap beginning tankyness. If you have built runes and masteries the way I have in this build, you don't have much early resistance. I build for early damage.

Why long sword and Pots

Long sword for the early damage and harass and pots because it replenishes your health. If you have health then you are not dead. If you are dead that means you have given the other team a kill. Given the other team a kill they are ahead and will win the game. So get pots.

Early Game Build

Mercury's Treads if they have good amount of magic damage and CC(crowd control)
Ninja Tabi if you are going agianst good amount of damage and need the armor.
I like getting Sheen first because it's a good early damage output and with Jax you use your skills a lot. You can combo your skill Empower with sheen and deal TONS OF DAMAGE.
Then build either Phage or Zeal and go for Trinity Force as fast as you can get gold

Early - Mid Game Transition

Guinsoo's Rageblade is a great item for Jax because it helps 3 out of 4 of his skills. His Leap Strike scales with ap and his Empower and his ult, Grandmaster's Might
Hextech Gunblade is good for Jax because of the slow active and the stats it gives. It gives both AP and AD stats which this build needs!


iceborn gauntlets. Once agian the stats and the passive. You use your skills a lot and the AoE slow is great after every skill you do. The added armor is great so you can get
Maw of Malmortius. Lots of people will not like this one for a item unless is necessary in their situation. I like it becuase most of enemies you will face will deal magic damage in atleast one of their skills. Maybe not like ADC but other champions. Also I know their are better items out their but this guide is not for you to be ADC, its for you to be the brut and be hybrid offtank. I mean the more armor and magic resist the better. Am I wrong?...probably

Your own items

This isn't really supposed to be a step by step item build but a general idea of how to build a hybrid Jax. This is a opinionated guide and you can build however you like! But this is how I build and I just wanted to share.

Many people may not like how I build my masteries, but like agian, this is a opinionated guide and this is how I build it. I'm trying to go for a good damage and health start. This is a normal mastery build for a top brut. Well from what I see. Anyway if you guys have better masteries that are better then please tell me!

Greater Mark of Attack Damage

Greater Seal of Armor

Greater Glyph of Scaling Ability Power

Greater Quintessence of Attack Speed

Jax is a AD champions so we want AD runes. Armor for early tankyness. Scaling of AP for late AP.
