[FEH] I am SO STUCK

This Limited Hero battle is kicking my arse SO HARD

enemy on the left coorner with Pass gets a special trophy as 'asshole of the day', too

since he sniped my Peony in the last attempt of clearing

Never thought I'd be happy to have Muspell in my party but here he is! Him and Surtr carried me so far. I just have no idea of how to handle this further level with only them as 5* that I can use

Fjorm and Eir are weak

Summer Freyr and Gunnthra or however you write that name are also going down SO FAST

I have Dagr and Lif who are good but Lif's weapon is getting me killed and I didn't invest in Dagr art all...

I was also unable to clear the Echoes map but hey, my only good unit there is Alm.
