Huh, well my build is just two physical items and three mahic items. Tough boots: cc, slow reduction. Endless Battle: for the true damage and hybrid life steal. Starlium scythe: same with endless battle to increase the passive damage. Concentrated Energy: for the 20% hybrid lifesteal and increase magic damage at max stacks. Feather of heaven: for the attack speed bc of his passive is pretty slow for me and can sometimes make the enemy clutch with 1hp and to also fully maximize the stacks of concentrated energy. Blade of despier: the passive of bane will work with this item's passive because if the enemy is below 50% hp than bane is deal more damage.
