This exploit involves running straight through mobs to reach a campfire so when you die, you respawn at it, skipping the mobs that were chasing you.
Method my group uses - have a rogue or gwf "train" (aggro all the mobs and start running) the mobs while the rest of the group waits because clerics and such are bad at training mobs. Then when the mobs start chasing the gwf or rogue, the rest of the group follows him far enough behind the mobs so they don't aggro onto them. You can do this exploit easily in karrundax and frozen heart.
