Reached by the DarkIn303 Targeter, converting the world to glitch blocks in real time.
Ghost World is entered by getting caught by the DarkIn303 Targeter. The dimension converts the entire world around the player, chunk by chunk in real time, replacing every non-air block with a glitch block. Every chunk also has a 1-in-80 chance of generating an exit pillar (Y 90-96, built from the EXIT block).
Only Ghost Humanoid and Integrion are permitted in this dimension, every other living creature, including ordinary animals, is discarded immediately on entry. Harmless Ghost Humanoid NPCs wander on their own (spawning roughly every 80 ticks, capped at 2 nearby, despawning within 5 blocks). Getting within 1 block of an EXIT pillar teleports the player back to the overworld spawn, or their saved respawn point.
