Late in the game, go to the Chamber Of Fate (located on the western side of the Everfall), and enter the first chamber. Proceed forward through the chamber until you cause monsters to spawn ahead of you. Then, turn around, and loot the two chests that were positioned behind you as you entered the chamber. Run back out the door without engaging the monsters. You can then turn around and go back into the cave, where the chests and monsters will spawn again. Repeat this process as many times as desired.
