This is a very old raid from FFXIV, and some of the mechanics are quite tricky these days. We were doing it blind without watching any guides, so had no idea really what we were supposed to be doing. Got to the one mechanics no one knew how to do properly and the group decided to ignore it and just try to kill the boss. But as you can see all but one of us died to the mechanics. The next hit from the boss would have killed our last remaining member, but the DoT (damage over time) from the healer ticked in time to kill the boss.

Pure luck, definitely no skills involved, we had no idea what we were doing and we were all just running around like headless chickens.
