my first build and well this is what i use when i go 3v3 it works wonders for me try for your self

ghost: helps chase and run away i find it great with rage blade and nashers tooth i hit for 2.6 atks per sec making the passive tick like crazy and ghost helps get those auto atks in on runners

ignite: i like it for when we do early ganks i ignite that 1 guy runing with 2 hp and it helps in many situations like stoping them from healing with the 50% healing reduction

i go for 21/9/0 i just like it works fine

i do this for early chase leap on runners and great spell empower over all its just juices up my spells. hit minions till your stun is up watch for enemies empower=leap stun and auto atk away with your ulti passive ticking away and spam your dodge and empower mid fight. i dont go dodge runes cause i go in with my stun up and during the fight i never found my stun was down its always up and changes team fights when spamed

all ap i feel is the best i play alot for my ulti passives to tick they tick for like 600 and happin once or twice a sec

speeeeeeeeeeeeeeeeeed alll about speed ulti passive ticks are broken take advantage leap empower and stun are all just icing on the cake

first build ever just thought i should share how i play jax i read alot of builds and took what i like but this is how i play 3s and i carry just about every game i play as jax
