Strategy
Fearsome, but only for people just beginning their journey into the LoC. Even without mana draining her, Granberia has a bad habit of wasting many many turns on buffing herself without actually attacking. More so, Inner Focused Mind actually kills her slowly, taking off 5% of her current HP (Which, at floor 300, would equal to about 112,875,000 damage if done on the first turn.), It only gets worse if you mana drain her, which removes 2 of her 3 Auto Hit attacks, leaving only her Dark Attribute attack as her most dangerous move. The rest? Completely nullified by Waning Moon Dance.

On the other hand, Granberia has among the highest base health of the super bosses, which does mean she might take a while to whittle down (Helped by inner focused mind, but still.) and unlike other super bosses like Yamata no Orochi or Sun Wukong, she is not weak to any status effect that would prevent her from attacking. Slow is moot - Either she's using her auto hit attacks or you're using Waning Moon Dance. Blind is even more useless for the same reasons. She also has no elemental weaknesses, even to pleasure. In fact, using pleasure might be a bad idea if it is your main form of offense, since Granberia can use Pleasure Eater and just absorb it. Best to stick to pretty anything other than fire/physical.

Being able to beat Granberia is merely a test to see if your team can handle the more dangerous super bosses, as among them, she has nothing that really makes her too dangerous. She doesn't completely prevent a form of attack, she doesn't get multiple actions a turn, she doesn't have attacks that go though deflectors... But even so, she is still a super boss. Don't underestimate her, and you'll be fine.
