Masker

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

Behavior
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 seen "camouflaged" in the form of a faint distortion shader seen at their location.

Strategy
Enemies will reveal themselves near the player as soon they attack, and will become invisible again if the player leaves their line of sight. Invisible enemies are also given away by traps and turrets as their targeting abilities are not affected. Killing a Masker will automatically dispel the fog.
