Bone Carving

The Bone Carving is used to summon the Bone Moon event. It can only be used at night. Attempting to use it during the day will not begin the event, and the Bone item will not be consumed from your inventory. The Bone Moon event will end at dawn (4:30 am) if not completed by then.

Crafting
RecipeThe Bone Moon is a hard endgame event with many different enemies and bosses. Your chances of completing it, or of killing enough enemies to collect rare drops, are better if you use the Bone the moment night arrives, to give yourself maximum time before dawn arrives and the event ends. (Use at 7:30 pm and you have 9 minutes to finish it.)
