Reality Vision

The reality vision is a joke helmet in 1.RV-Pre1.

Zombies, zombie villagers, skeletons, creepers, and endermen can spawn with reality vision on their head. They have a chance​[more information needed] to drop it when killed by the player.

Reality vision is equipped via the helmet slot. When equipped, it shows a minimap in the bottom-center of the screen (which moves when the player's camera moves). The minimap shows all chunks that were currently rendered. The player's location is represented by a light green beacon beam marker on the map.
