gift from the princess who brought sleep

Thank you so much! It's a great song choice!

I don't know if you're still looking for an answer but you can use mass attacks to cancel the move to drag people into the dream world. Just target that page with literally any mass attack and bam, no more dream duels.

Ah, I fought her before I had access to mass attacks, but thank you for the advice!

the first dream self is a beast, throw your lest valuable guy to it.

the least fun modded boss ive ever fought

just beat the boss after a 2 hour long attempt that died before i could kill her, putting here that while the shields sound like they punish you for hitting the 100hp cap, since she can only be hit AFTER the next turn, you can spend one turn doing 100, the next turn you eco and do the shields health, and then you can rinse repeat. this with selinites tip on mass attacks (which you should have up by 3rd dream card played from my experience) should make the fight far easier! (still fights like hell when you get her low those defense die rolls dont ♥♥♥♥ around lmao)
also i reccomend (worked for me at least) yesods floor, Der Freischütz syncronise gives spammable ego attacks and the million extra damage passives make the thresholds a joke once you get some emotion levels, not going to get much use from solemn lament though, one siding the princess is a pipe dream by the time you get it
