I read online that after beating Bergen I should have unlocked a ton of spells like Esuna and the Ra level spells but the spell shops are always the same as they have been with no Ra level spells or Esuna - am I missing something?

I’ve read all of Gaunts Ghosts, Eisenhorn, Ravenor and what’s released of Bequin. Have also read Ciaphas Cain and Vaults of Terra and eager for more.
