Teemo, Singed, Ornn, Illaoi, Renekton, and Neeko are Jax's main opponents. Teemo and Neeko can poke Jax effectively while avoiding damage if they play correctly. Renekton and Illaoi are both capable of killing him. Ornn is a good counter to Jax because of its ability to freeze targets which prevents them from attacking or using abilities. Jax's kit allows him to deal significant damage to most targets listed above. His W (Thrash) and E (Violent Swing) both do area of effect damage based on how many enemies he hits with them. This means that if you can get multiple enemies in range, you can use these attacks to clear an entire wave of monsters. Jax's Q (Twisted Fate) creates a periodic shield that reduces the attack speed of all nearby enemies by 15%. This can easily be maintained by switching to a second target so that you don't have to keep paying attention to your first target's attack speed. The shield lasts for six seconds or until Jax takes damage. He cannot move during this time so stay away from him unless you want to take more damage than necessary. Jax's ult, Sanguine Pool, places a pool of blood around him that does extra damage to enemies it hits. This can also be used to clear waves of monsters as long as you stay out of the pool yourself.
