i love me some jax. so my goal with this build is to make is so if you time it right, if you "w" "q" onto someone, having your ultimate's passive bonus damage ready, along with triggering triforce and ionian spark, your attack against your target should do somewhere around one thousand four hundred damage. damn. also to increase this "one hit wonder" theme, try switching out nashors tooth for ionian spark later game. hope you like the build, have fun.
