Unless you really know what you're doing, you're going to need barrier and stone skin on top of aura and shield. Invoker shields if you can get them, make friends with bards for resisting. Either that or stick and move a lot AWAY from the village, heal up and then catch them weakened. I get pwned by deathblow too, but when I do the ragers are usually classy and don't really loot much. More often than that though it's me who's harassing the ragers, not the other way around. Learn their weaknesses and exploit the fuck out of them.

They're battleragers, they're the toughest of the tough. It's not expected for you to be able to just go toe to toe with them without preparation and planning. Don't ever forget that.
