Blackout

Blackout is a challenge in Risk of Rain 2. The achievement is obtained by defeating Aurelionite in the Gilded Coast stage before the beacons deactivate.

Tips

 * The Engineer makes this challenge much easier since his shield can block Aurelionite's laser entirely if timed properly, avoiding the time loss caused by hiding.
 * Lowering the difficulty and going to the Gilded Coast quickly also helps, Aurelionite's health increases much faster than any other enemy in the game as time goes on making it much harder to complete this challenge if you wait too long before going to the Gilded Coast.
