Key Features of the Disc Thrower

• Returning Discs: Fires spinning projectiles that boomerang back after impact.

• Secondary Fire: Unleashes three discs simultaneously, amplifying destruction.

This weapon excels in skilled hands, rewarding precision and tactical play.

Unlocking the Disc Thrower

After defeating the Act 2, Stage 4 boss (Depth 8), a sealed red door blocks progress. To open it, locate and destroy four hidden red crystals:

• Crystal 1: Embedded in the left-side grating near the door.

• Crystal 2: Hidden in the grating by the pond’s right edge.

• Crystal 3: Positioned in a vertical grating near the upper exit.

• Crystal 4: Located in the upper-right grating facing the door.

Destroy all crystals in any order, proceed through the unlocked door, and claim the Disc Thrower from a corpse in the adjacent tunnel.
