This a tank/damage jax that works well if you can get the gunblade quick and the belts for the mallet and the scepter. The Rageblade is really an optional item since its a temporary stack item. But since Jax's passive increases his health by both his ap and ad, you can do major damage and stay alive in one versus one and possibly one versus two situations. You'll also want to max empower first since its more damage than the jump. And max counter strike before because it does damage as well as stun them. You can also gank enemies early on because of the jump-dodge-stun technique. When ganking an opponent make sure there are enemy minions. The minions attack you, causing the dodging, then you jump to the champion and stun him, then use empower as much as possible.If he runs, then use jump and stun again. Basically the whole game you want to be the initiator in team fights and the damage. Remember to stay close to enemies and stun as much as possible. The Empower and counter stike are your bread and butter.
