Phantom Blade

The Celestus is a craftable post-Moon Lord rogue boomerang. It rapidly throws high velocity scythes which can pierce through infinite enemies and pass through tiles. Each time the thrown scythe strikes a target, it emits a dozen double-edged phantom blades outward from the point of impact. The phantom blades deal 70% of the scythe's damage and can also pierce infinite enemies and pass through tiles, but cannot create even more blades by themselves.

Performing a stealth strike with the Celestus causes the resulting scythe to rebound inaccurately when returning to the player, homing into the nearest enemy but no longer pierces. The scythe will not return to the player for the second time when rebounding.

When Celestus or any of its phantom blades hit an enemy, they will inflict the following debuffs:

On enemies, these combined debuffs cause the target to be completely unable to move, lose 113 health per second, have their defense cut in half with an additional 34 defense loss, and become unable to regenerate health. In Revengeance and Death Mode, they will also lose 20% damage reduction.

Its best modifier is Flawless.

The Celestus in use on an array of Target Dummies.


  • Only the rogue variant of the Elemental Disk can be used in crafting the Celestus.


  • This weapon greatly benefits from Nanotech. Every time it splits on enemy contact, each projectile can spawn the homing blades.


  • "Celestus" is the name of a genus of lizards.
  • Although the thrown weapon was redesigned in update, the split projectiles still use the old sprite.
