So enlightenment is new, and happens on the moon island. Your sanity basically translates to enlightenment. But what if you want a way to keep it, even on the main island?
I present the idea of the lunacy charm, and item that, when worn, keeps your enlightenment, or switches sanity to enlightenment. To obtain this item you must kill the deer clops and mix his eye with some nightmare fuel at a shadow manipulator. The item can then be worn in the armor or headgear slot.
But whatever, just a thought I had for some more content on the enlightenment, since it is in testing.
