Champion Background Strategy Skins & Trivia

Skill usage

  • When laning,  Jax is an excellent zoner when in the brush, because his  Leap Strike -  Empower combo enables heavy harassment with a lot of pressure. Be careful as these two abilities drain a lot of mana.
  •  Jax can use  Leap Strike to leap into the fray of a fight or make a quick escape when necessary due to the fact that  Jax can  Leap Strike towards a friendly unit. You can use  Empower to maximize your burst potential when using  Leap Strike.  Counter Strike can also be used right before  Leap Strike to lead to an instant stun.
  •  Empower is most effective when used as quickly as possible after a basic attack. This, in addition to granting the bonus magic damage from  Empower, effectively doubles  Jax's base damage output for that attack. Since it is still another attack, it also counts toward building up  Relentless Assault and  Grandmaster's Might's passive, so those are accrued faster by using this technique as well.
  • While engaging with  Counter Strike seems to be a safer option, activating it after you take some damage can bait your opponent in focus-firing at you, thus mitigating more damage and may causes your enemies to be over-committed in attempting to kill you.
  • Activating  Grandmaster's Might right before a fight will increase your resistance to both physical and magical damage.
    • Note that  Grandmaster's Might has a rather short duration of 8 seconds and a cooldown of 80 seconds.  Jax usually doesn't need it a in 1v1. Save it for team fights, where it's really needed.
    • If used at mid or low health, it can bait an enemy and make him over-committed to kill you. It has nice synergy with Maw of Malmortius, getting extra armor and making the item's passive more useful.
  •  Jax can jungle effectively with  Relentless Assault and  Empower, ganking with  Leap Strike and  Counter Strike.  Counter Strike can be used for killing stronger monsters without losing much health, but you are more vulnerable to ganks when it is on cooldown. Careful if the enemy counter-jungles.
    • At level 2  Jax is extremely potent at ganking combining  Leap Strike with  Empower to deal massive damage, although he should continue to jungle until level 3 for the stun from  Counter Strike.
  • In 3v3, there can be a lot of fighting even before minions come.  Counter Strike is good for getting early first blood, since you can use it both for dodging and stunning the enemy. It can also help you on solo top, especially against champions who depend on autoattacks. You should max  Empower though; you can use it many times in a longer fight and it helps you heavily with jungling and killing  Vilemaw.
  • While playing against a  Fiora or  Warwick, you can dodge their ultimates with your  Counter Strike; it might save you from a gank or team fight.
  • Be patient with  Jax. Often the opposing team will focus you down due to your high damage output. If you are having a bad game, just focus on gaining gold through minion kills, kills and assists, and jungling. Once you get the items you need, you will be much harder to kill.
  • Be careful in team fights with as  Jax is a high priority target for the enemy team due to his high damage output and squishiness.  Jax is reliant on his team to support him so make sure that you are on a team with initiation and hard CC and that you are at most the third person to enter the fight, behind your tank and off-tank. Try to save  Leap Strike to escape when getting focused, rather than to engage on an opponent.
  • When reaching level 6,  Jax can become a strong lane zoner. Try hit minion twice and then quickly use  Leap Strike into an enemy champion and attack him or her with third attack to proc your  Grandmaster's Might's passive. You may also activate  Empower to maximize damage output. However, pay attention to your mana pool.

Runes and Masteries

  • Being that  Jax is a mainly offensive champion, he is probably best with offensive masteries. Offensive masteries (21/9/0) are seemly better for his damage and with defensive masteries (9/21/0) there is a noticeable decline in his damage while not providing the survivability that one would expect.
  • A rune page of attack damage and ability power per level can give a powerful scaling amount of bonus damage on all of his abilities, or a flat attack damage and ability power rune page can give a massive burst of damage on  Leap Strike and  Empower for laning, leading to an advantage over the opposition during the early and mid-phase of the game. This is especially useful for shorter games, such as those on the Twisted Treeline.
  • Jax can also make use of attack speed  runes effectively as they improve both his physical damage (in basic attacks) and magic damage ( Grandmaster's Might's third hit).


  • Try to shut down  Jax early in the game because once he hits level 6 and obtains  Grandmaster's Might, he becomes increasingly hard to fight 1v1. Ganks from the jungle and zoning him can make him under-farmed and under-leveled, delaying his items and scaling. Although  Jax is very strong at late game, he is fairly weak early without sustain.
  •  Jax primarily deals physical damage. Concentrate on armor items to counter it, especially items that slow his attack speed.
    • Frozen Heart and Randuin's Omen are the only two items that slow attack speed, but they both also have high amounts of armor. Where the latter is generally reserved for tanks, the former is viable for a larger variety of champions, thanks to the CDR and high amount of mana.
  •  Jax can also deal a fair amount of magic damage and, if he builds any spell vamp, it could be his source of sustain. Magic resistance can go a long way to counter that.
  • Most  Jax item builds involve him building mostly glass cannon due to the fact that his offensive stats will grant him defensive stats with  Grandmaster's Might active. Consider focusing him down first in teamfights.
  • Remember that  Jax is a melee fighter with only one ranged gap closing ability,  Leap Strike and a heavy reliance on staying in attack range to keep his passive,  Relentless Assault, stacked. Any crowd control to disengage after his  Leap Strike or simply staying out of  Leap Strike range can nullify his only engage.
  • Try not to let  Jax stack up his  Relentless Assault passive before he engages on you. You probably can't compete with 84% attack speed.
  •  Jax mainly combos his gap-closer along with  Counter Strike. If you have an escape or a gap-closer on your own, you can use it after he closed the gap with you to escape his stun.
  •  Jax relies on getting close to his foe to land a stun. Try keeping a safe distance for a few seconds after he uses his  Counter Strike.
  • Focusing  Jax when his  Counter Strike goes on cooldown is one of the best ways of getting rid of him. But since he is one of the best duelists in the game due to  Relentless Assault and the high AD and AP ratios he has on his single-targeted abilities, try to not to fight him alone and outnumber him.
  • When he activates  Counter Strike, avoid grouping around or being close to another teammate when the AoE stun activates.
  • Keep in mind that  Counter Strike only allows him to dodge auto-attack, abilities will still damage him. However, note that Area of Effect abilities are still reduced.
  •  Jax is considered to be one of the best late-game duelist and split pusher due to his  Relentless Assault, his sustained damage through  Grandmaster's Might's passive and  Empower, free defensive stats from the said  Grandmaster's Might's active. Do not try to 1v1 Jax late-game unless you are certain that you can win the melee trade.
