agreed.
abyssal princess was fucking dumb as hell, like i go through this every single time i fight a superboss in the etrian odyssey series, but abyssal princess is probably the second worst of the superbosses that i’ve fought against (behind abyssal god in 3)
spastically speaking her stats are high enough that almost all of her attacks will one shot every non-heavy armor in the party, and any defensive countermeasure you can take against her gets cleared because her unholy light skill cleanses her and you
oh and later in the fight she also reads your inputs so she’ll use her fast activation move to hit before a guard skill comes up. and her elemental pattern for attacks are random
overall an unpleasant experience, i needed a lot of rng to beat this fight on heroic
