I was very fortunate and cleared it on my first try. Fortunate because I got one of the very easiest paths through the later floors (Sphinx, Venus, Mercury, Gran, Athena, LKali).
The team is still far inferior to Ra and Yomi Dragons, but Pandora still made the dungeon feel pretty damned easy. Damage and healing were never a problem, but I can see the lack of time extends being a major one. I got Minerva and it was pretty difficult to pass her five-combo shield as making an eight-orb match takes up a lot of time. I could see something like Stratios’s five-combo shield being quite difficult to get past; an eight-orb match with five additional combos sounds quite daunting. At least for shitters like me, uuevo Pandora is an ideal sub. I actually think Game8’s template party of Pandora / uuevo Pandora / DValk / Zuoh / Akechi / Pandora is pretty close to what I’d run normally as it has that sweet spot of RCV and time extends (probably swap out Akechi for Loki for Arena clears?).
By the way, I noticed after the fact that my Loki is not max skilled… I seem to recall making a similar mistake with Freyja.
