We have begun migration of most wikis to our new host, Amazon Web Services. All but the top 100 wikis are in read-only mode until the migration is complete. Estimated completion: TBD -- Update: Fri 10/20 11pm UTC - We have encountered some unexpected issues. Our staff is working around the clock to complete this process as quickly as possible. Thank you for your patience.

The Creeper Egg is a Hardmode summoning item that gives the player a Flickerwick light pet. It is dropped by the Ogre during the Old One's Army event. When active, it is similar to the Wisp in a Bottle, where it provides light where ever you go. The summoned Flickerwick has the same movement speed as the player, and cannot be left behind easily.
