50 stamina only existed at the time this video was done.
Don't need patting bonus on Mitsunari Ishida. Did take me multiple tries if enemies focus 1 girl nonstop.
Mitsunari Ishida, Maeda Toshimasa, and Honda Tadakatsu friends will work too. Just need 2-3 CC AOE skills for boss wave to have an easier time. Using Maeda friend is tougher due to not having CC skills.
Edited: At the time this video was done, it was where DMM Senpro decided to make daily event girls much tougher. Fujin and Raijin were the start of this difficulty spike. Raijin was doable, but Fujin is whole another level. Then the whole mess of Tengu that came after where it's nearly impossible to do without very specific girls. They only have 50 stamina at the time aka Hell Mode (not official term, but it's harder than previous events 50 stamina Hard)
