The Celebration is an endgame-tier weapon that can be dropped by the Moon Lord. It uses rockets for ammo and fires two rockets per shot, along with exploding into fireworks when the rocket hits a enemy or goes a certain distance, making it extremely effective for large groups of enemies who are close together.
- If the player uses Rocket IIs or Rocket IVs with this weapon, they will not destroy tiles.
- The fireworks released from the Celebration will do damage as well as the rocket.
- Added to the game.
