All right, I think I may have HeraDra more or less figured out? At least, I've probably got her beat if I can get to her...
Revo Hades/Revo Ceres w/Awoken Sakuya (gravity works, right?)/Awoken Pandora/Awoken Tsukuyomi/Yomi Dragon, with bindproof badge
If I understand it right, the 10 turn bind should only hit Pandora and Tsukuyomi, leaving the rest unbound, but just in case, Ceres active + heart row should clear the last 9... right?
Awoken Tsukuyomi can help push past Ceres' stupid combo drain.
Hera Dragon's strongest attack will only do a mere 20597 damage to me, which I can tank... but getting health up may be a pain. I'm considering dropping Ceres for Halloween Thoth and Sopdet with their 4 dark resist awakes... but that might make the rest of the dungeon rougher. What do you think?
