Darkness

Darkness is a status effect that causes the player's vision to temporarily deteriorate. The effect is caused by the activation of a sculk shrieker, or by being within detection range of a warden.

Effect
Darkness, when applied, dims the player's vision. A dark vignette appears around the player, which initially makes faraway objects hard to see. The vignette then steadily closes in around the player, diminishing the player's eyesight. When the effect wears off, the vignette retreats and the player's vision reverts to normal. Unlike Blindness, a similar effect, Darkness does not leave a circle of unaffected vision centered on the player; moreover, luminous objects such as fire are still possible to see even when viewed from far away by a player with the effect applied.

Strangely, Darkness does not cause its dedicated particles to appear around the player when it is naturally activated, nor does its icon appear in the player's heads-up display. However, the particle still appears when it is triggered by command, and its icon can be seen when entering the player's inventory.
