Over the past few weeks, Shroud’s raid team dedicated quite a few hours to learning and progressing on mythic Mistress Sassz’ine. Going into the fight, we knew she was essentially a Gorefiend-equivalent wall, so we were prepared for a lot of early wipes and a fairly long progression time.
We changed some of our strat throughout our time on the boss, trying to find the best tactics that would work for us. That meant first using a burden to clear the first set of bufferfish, although the timing could be tricky and it also meant a huge amount of damage on the raid. We also tried using jellyfish to clear, but that meant a lot of dispels for the resulting stuns. Finally, we decided that dropping them earlier, using the first set of murk dropped by the adds, made the most sense and was the easiest way to go about dropping the fish.
Once we were into the second phase, we had to position ourselves so as to not accidentally stack hydra shots while also avoiding ink and crashing waves. Additionally, people picking up fish needed to avoid damage in this phase to maximize their uptime on the buff.
Hydra shots, in general, were one of our biggest hang-ups throughout progression. We used a weak aura to help facilitate soaking, but there were times when we either goofed and simply missed a soak, or when hydra shot placement was a bit off and soaking would mean getting stunned for half a minute. Eventually, we became better at soaking in general, but even now there is still room for improvement on future kills.
Moving on, once we figured out the nuances of the second phase, we were steadily getting past it and going into the last phase. This phase was by far the most hectic, especially considering how long it lasts. There would always be a lot of things going on and this was exacerbated by having much of the encounter area filled with ink that we would attempt to clear as much as possible. As such, we regularly had trouble trying to get her to around 20%. At this point, though, the fight became about trying to perfect our reactions to her abilities and prepare as much as possible for overlaps and use defensive cooldowns for soaking shots, if we were able to do so. This sometimes meant sacrificing people just to keep the rest of the raid alive and keep incoming raid damage as low as possible.
Our wall on this fight came with the last 15-20%, as lust was gone by this point and we were trying to survive by the skin of our teeth. We would regularly get her to around 20% and then begin falling apart as damage kept ramping up.
Throughout our tries, we kept getting her lower and lower, finally damaging her to around 10% on some of our best wipes. From that point, it was all about minimizing damage taken, maximizing bufferfish uptime, and staying alive as long as we could.
Last night, we managed to do all of that and finally earned ourselves a kill on one of the most difficult bosses we have ever fought.
Congratulations to all involved! Next up: Maiden of Vigilance.
