Stargazer

The Stargazer is a Hardmode, post-Lunatic Cultist enemy found at the Stardust Pillar during the Lunar Events. It walks slowly, and will sometimes fire a thin Stardust Laser at the playa. The Stargazer may move while firing the laser, but it cannot change the angle, similarly to the Charged Blaster Cannon on when firing its full beam.

Trivia

 * The Stargazer is named  in the game code.
