A blur artifact (also known as an invisibility sphere or partial invisibility) is a powerup that appears as a floating red orb with a blue eye-like pattern. Picking one up will grant the player temporary partial invisibility. The player's sprite (as seen by other players in multiplayer mode) will be given a filter similar to that of the spectre, while the affected player will see their own weapon as partially invisible. When 5 seconds remain, the weapon will begin blinking, signaling the end of the artifact's effects; the player's sprite, however, remains filtered until all 60 seconds have expired.
Monsters firing upon an affected player will have their accuracy reduced, in that their aim is offset by a random angle, causing them to miss more often. This, however, may cause more experienced players to inadvertently dodge toward hostile fire rather than away from it. Nevertheless, a blur sphere bestows an advantage against hitscan attacks such as those of zombies or Spider Masterminds. On the other hand, the invisibility is unable to disrupt monster melee or Arch-Vile attacks (even though the monsters do appear to spin around in confusion).
In deathmatch mode of vanilla Doom, blur artifacts and invulnerabilities never respawn. Some source ports allow flags to be set to allow them to respawn.
Blur artifacts are included in the items percentage displayed at the end of each level.
