Selenians are a humanoid enemy that is spawned by the Solar Pillar during the Celestial Events. It is a ground based enemy that has 2 flaming swords, but can curl up and fly at high speeds towards the player. When it does this, certain projectiles you have fired at it will be reflected, like the Vampire Knives' projectiles. This is very dangerous as some weapons like the Sniper Rifle and Meowmere can potentially deal over 300 damage to the player.
- When it spins, it reflects projectiles.
- It seems the Selenian's defense is greatly decreased when it spins.
- Reflected Chlorophyte Bullets will target the player.
