HC Viable, BoR, Long Immortal Call/Vaal Haste, Max Block/Spell Block, Crit Molten Strike

This build is designed around using 6 Endurance Charges + 45% Increased Duration from the tree for long Immortal Call's and Vaal Haste. It will also be using Bringer of Rain, Rathpith, Stone of Lazwhar for 75% Block/Spell Block. I run Blood Rage for the frenzy charge and life leech. Mana leech will take place from gear.

On the offensive side I have decided to use a mace, due to the excellent nodes along the current defensive path of the tree. You can use Lightning strike, Molten Strike, or Glacial Hammer as your skill of choice. I have a crit tree and a tree with resolute technique.
