Completed the game on balanced experience.. Didn't upgrade any of the armor or runic attack as I knew best armors will be available at the end.. Became bit easy at the final third after leaving up.
Have changed settings to give me a challenge after end game.
Killing valkyries and doing challenges in Muspelheim and Niflheim.
Have killed 4 valkyries sofar, in lvl4(kill 100 enemies) Muspelheim, 2 tear and 1 legendary chest pending in Niflheim.
Using sindri chest, ivaldi wrist and valkyrie waist armor with valkyrie pommel.. Ivaldi waist for Niflheim..
