Talk:Hallowed Key Mold/@comment-24076955-20131030055024/@comment-1466854-20131030123428

Same as any key mold, and previously any key. Just kill enemies in hallow, or in a region that has enough (not sure how many exactly) pearlstone. If you slap a few layers of crimstone, ebonstone, and pearlstone on top of each other in an area, you can farm crimson, corruption, and hallowed key molds all in one spot. Do it right, you can farm for all five, but I'm not going to explain how to pull that off.
