The Lunar Siphonator, also known as the completed form of the Incomplete Experiment, is a craftable structure exclusive to Don't Starve Together, introduced in Return of Them.

The Incomplete Experiment blueprint will be given to players by Wagstaff upon entering a Moonstorm for the first time, along with the blueprint for the Astroggles.

The Incomplete Experiment serves as the first stage of the Lunar Siphonator and can only be built over the Mysterious Energy spawned by assembling the Celestial Altar, Celestial Sanctum and Celestial Tribute nearby to one another.

Similar to the Hermit Home, it is crafted in stages by adding materials for each upgrade:

Therefore, the total cost of building the Lunar Siphonator is:

0.4655-1.064 seconds after the completion of Stage 3, 6 meteors will crash down within 10-19m around the structure, which will destroy it and spawn the Celestial Champion. All structures within 15m will be destroyed, and all workable within 15m will be worked. For instance, any rocks will be mined and any trees will be chopped.
