Hello again!
We fight the boss in floor 15 in Aura Gate 2. Unlike the boss in 14F, the adds here have quite a bit more HP, around 8000 - 9000. Since the boss also only has around 11000 I decided to just focus Scathach down this time. Since then only weakness here is wind on Mothman, you could bring a demon with a wind attack to fish four Weak Killer procs.
Besides that you have to deal with Fog Breath, which can be ignored with lucky Weak Killer Procs or buffs of your own. The other annoying thing is probably Mahashibaboo from Mothman, especially since he also comes with Insanity. I got lucky and got a mute proc on turn 2, so I didn't have to deal with it. Scathach herself is probably the least of your problems, especially if you use Sukukaya/Sukunda so her attacks miss.
Overall, more interesting than 14F, but still not hard. I am pretty confident I could reach 20F and also beat that boss, but beyond that I am not so sure. So let's see how far I can get!
