Some people mentioned the overpower skill with revel rune here.
i'm using overpower instead of furious charge but with the best rune for it:crushing advance.
During 4 sec after using the skill , ALL MOB hitting you in melee or range will take 30% of the damage they deal AND PROC YOUR LOH.
And it works with lava and some other environment too..
in a build with a high crit rate, and 2000+loh , u can keep it on you in a big pack of mobs and gain an insame amount of hp.
Plus with this skill and rune ghom is a joke...
