Cosmic Duo are a post-Moon Lord duo that will be fought anywhere in the world, comprised of Daeitus and Ethignus.
The Cosmic Duo do not spawn on their own and must be summoned by destroying the Mysterious Meteor.
- Daeitus' theme will be Interstellar Impotance, by Shadow Figure.
- They are not included in the new public demo, trying to fight them after destroying the Mysterious Meteor will cause some dialogue saying that they aren't in the game yet.
