All you need to know is this skill sequence and item build. there are many builds and videos our there that will give you great ways to play jax.. As the title emplies, this build is to show how to solo baron extremely easily. as soon as madred's is complete and your bf sword is bought you can take him on alone. should end quickly too. not to mention this build will give you absolute ownage.. Notice i placed trinity force at the end.. With the cdr from runes, masteries, and blue buff, there is no need for the trinity proc. Also your slow is already there from the frozen mallet and 15% crit chance isnt worth worrying about. However it does do decent damage output and adds a little beefy-ness to you so i included it as an option.. might want to substitute items for defense depending on how the opposing team builds. there-in ends my ramble. thanks
