UQ: Crimson Fellwyrm Over the Castle

On the launch of EP5, we got our first UQ on the second week with the Crimson Fellwyrm (fan translated as Crimson Castle Crushers in JP). During my time playing PSO2 JP, I never really got to do this UQ when it was still in the schedule and only did it a few times after they cycled it out nearing the end of EP5. I’ll try my best to go into the details of this UQ and then provide some advice from my own runs on the 4-man party version.
