Anyone else struggling with the Alyssa / Dariana fight? My whole party is lvl 25, same as them, and they're just wiping the floor with me. What am I missing?
I would guess you were missing training Seles to use smokescreen and keep the two constantly blind/confused, while Eileen saves all her CP to heal and Kaie also blinds whenever both the confusion and the blind from Seles misses or wears off.
Besides that, generally when fighting several strong enemies, focus all fire on one, then as soon as you bound her, secure her bindings at least once. Then you really don't have to worry about her anymore (Alyssia didn't even struggle, she just glared all the time. Maybe the AI decided its hopeless)
