Much, much harder. I just managed to finish the trails of Muspheliem after grinding out gear in Invalids dungeon and man was that a task and a half, too the best part of two evenings just to get past the valkerie, get the three keys and finish the last task Some of the valkeries are harder than any Souls-borne boss I've come across bar one from the chalice dungeons in BB and I went down to balanced, I can't imagine the pain it would be on the second hardest difficulty or god forbid the hardest.
Are you fucking kidding me? I have finished the game and didn't even visit Muspheliem Once, was saving it for post game thrills. I dabbled into inalids dungeon before completing the game jut to get enough mist to get the mist amor and even then I felt that shit was too hard and I was probably to go to the fire realm first before coming there. And now you tell me you had to grind at invalids to be better suited for muspheliem...... damn.
And I am playing on the second hardest difficulty, managed to beat two of the valkyrie just before beating the game so now I am trying to power everything up before taking on the rest.I am actually scared now lol.
I hear there is also more after you defeat the nine valkeries
Music to my ears BOY!!!
