blessed hammer pally

Well i dunno lot about his gear i havnt talked much to him since i stoepd playing my zon. But i know he use Wiz spike and Zakarum. The damage when Blessed Hammer is high become huge ! Mostly when synergy are maxed. Since synergy affect blessed hammer directly the bonus gained from synergy is affect also by Concentration and it s where at least 2/3 of the dmg come from.
