This build was initially potatopeelers Hack n Slash but i toyed with it and put exactly how i buy the items and how i played him. My version is mainly for chasing down champs and smashing mobs. I start of playing it safe at first. stay in the lane for as long as you can by using bloodlust when it is fully charged to heal. if you die you are loosing precious money and XP.
once you are level 6 you get undying rage. use your spells sparingly ! when you use undying rage wait until you are lower in health and then pop it on. you want to make your enemy overexert to kill you. once you are about to come out of undying rage hit heal and bloodlust.
If enemys try and run make sure there back is against you and use mocking shout and spinning slash. repeat until they are dead.
Have fun! crit a ton! and play well!
