There is a LOT of things in this area that do magical damage. Save for the Golems. They punch hard. Not as hard as the Myconids in the Darkroot Forest, but I digress. From the Duke's Archives, I come to the Crystal Caves, a place filled golems, Moonlight Butterflies, invisible pathways and falls to instant death.
By the way, Youtube tells me this video may be out of sync with it's own audio. If so, tell me in the comments, k thnx.
