Okay cool. I've run a couple of combos using 300 vit the rest dex and I'm getting exp comparable, if a tiny bit lower than my previous hybrid dagger build, with only 600 ability for hand to hand. Using way less restos too, which is nice
Yes, dex survivability is awesome. You may need more hp but that's an easy fix. Also, I suggest lvling h2h more. I recently am trying spear out and without leveling the new ability, your lixes won't be close to as good.
Also, overall, at mid to high levels, knuckles have really lost their power. I suggest switching back to dagger or giving spear a try because knuckles kinda suck at high levels
