Masker

Maskers are supportive, stationary enemies. They cannot attack, but instead cover the vicinity in a dense fog, rendering other enemies invisible.

Strategy
Maskers emit a fog that is easy to spot as the player approaches. Enemies under the effect of this fog are not truly invisible, as their silhouette can be see "camouflaged" in the form of a faint distortion shader seen at their location. Enemies will reveal themselves near the player as soon they attack, and will become invisible again if the player leaves their line of sight. Traps and turrets will target invisible enemies.

Killing a Masker will automatically dispel the fog.
