Blackout

Comparison between Blackout debuff (right) and no debuffs (left).

Blackout is a debuff that significantly decreases the player's light vision. It can be considered a stronger version of the Darkness debuff.

Causes

From		Duration	Chance
	Ragged Caster	2–6 / 4–12 / 5–15 seconds	1/1 (100%)

From	Duration	Chance
The Torch God	For the whole duration of the event, while within range	1/1 (100%)

Unlike the Darkness debuff, equipping a Blindfold, Ankh Charm, or Ankh Shield will not provide immunity to the Blackout debuff.
In the Desktop version, Console version, and Mobile version, the character's sprite appears to close their eyes while this debuff is active.
