The Sinister Sculptor can manipulate earth, wood, and other materials to form horror structures, leaving behind sculpted remnants that glow with an eerie green light. It emits a low, grinding sound like a film projector when active, and its tools, made of ossified fear, allow it to reshape course features seamlessly.

The Sinister Sculptor ensures that each league's horror subgenre is physically embodied through course transformations, creating immersive set pieces that challenge players and maintain narrative continuity.
