-Spoiler- After defeating the main DLC boss...

After defeating Manus what's supposed to happen to Dusk? It might have been asked already, but using the Search function provide no results.

I killed her (i'm evil) and Elizabeth disappeared leaving 3 of her mushrooms.

Please let me know what you managed to discover.

P.S. Where do you get the Black Flame piromancy?

Nothing happens with her. Thats just the 'end' of the dlc. Aaaaand, unfortunately i forget where i picked up the pyro spell. Its damage is just bout the same as GC
