Grenth's Balnce?

I've been trying to make a good W/N build that uses Grenth's Balance. My plan is to use it against some of the high level bosses, like Kuunavang, Shiro, and Zhu Hanuku. I've also thought about incorporating Spinal Shivers combo'd with an Icy sword. Is this idea viable? And what kind of other skills should I take? I know Endure Pain is useful, anything else I should know?

Anything that raises your maximum health helps. Signet of Stamina is a good one, you just can't keep it up while you fight. If you're looking for Spinal Shivers, get a Necro to cast it for you, trying to do everything yourself will result in you being crap at pretty much everything.

This would only be useful when you take alot of damage and know you can spike it back up reliably. Against bosses like Zhu Hanuku, who are really quite easy, this build is useless as you can out-damage it with a D-Slasher.

Spinal Shivers on a warrior is lose, you'll run out of energy very quickly with a ~20 max and 2 pips. Let the SS do it.
