A link to the verification screenshot for each boss you have defeated:
Nefra - SS -
Note: Sadly I didn't get the UTC clock to show up since I totally forgot to take a screenshot so I just took it from a guild mate. The time on that screenshot is UTC +2, also you can see it on the video.
Congratulations to everybody else who has achieved a kill or cleared up nightmare thanks to DNT for giving us a general idea of the fight.
