Took my barbarian into the Snow explorer area and the Prey quest...
I figured out pretty quickly that DPS was worthless, so I put away my big greataxe, and instead pulled out two weakening of enfeebling weapons (much easier to find than w/p).
But I didn't see much effect... I don't think I ever saw a Giant drop to 0 Strength (and auto-crit). I tested it again after the quest on the first giant in the explorer area and I never got to the auto-crit stage, and he continued to hit me hard the entire time.
Are they immune to str damage??
I finally went on the AH and bought a wounding dwarven axe and wounding hand-axe, went back into the explorer area and killed the first giant fairly quickly....
Bug or intended?
