When an anomalous vision appears, its presence is announced with a sound effect similar to a thunderclap. It will appear a random distance from the player on the surrounding terrain, often not in the direction the player is looking, and will disappear after a short time.
- Touching an anomalous vision will unlock the hidden achievement Burden of Choice.
- Each anomalous vision only spawns client-side, possibly with the intent of making players appear to be "crazy" for seeing one when others cannot.
- The anomalous vision itself has no in-game name, and is not targetable; the name "Sad Anomaly" was given to it by the community as it seems to be performing the /sad emote.
