Returning Eye

The Returning Eye is a Hardmode boomerang-type weapon that drops from the Eye of Cthulhu when it is killed with a weapon bound with the Spirit-Studded Tome.

The Returning Eye behaves and looks like the Eye of Cthulhu's second stage. It can pass through blocks like the boss, and when thrown, it doesn't spin, but faces the direction it was thrown at. Once it reaches maximum range, it will face the player and return.
