Boss Rush Megathread

Hi all!

Considering the new influx of boss rush related posts that are appearing on the sub, we thought we would introduce this megathread temporarily.

Please could we keep all posts related to boss rush, such as clearing, clear times, team strategies and general discussion regarding the mode and its new stages in this megathread? Teambuilding can also go in here, but it's recommended to use the teambuilding megathread where lots of helpful users would be willing to help out.

Thanks in advance everyone!
