Jotun: Valhalla Edition

This might be hard one to understand but is quite simple to achieve. Just start the fight with Fé with a regular attack and then run away as far as you can, she"ll start throwing her shield at you which you can reflect if you hit it with a heavy attack. If you succesfully reflect the shield 3 times she'll spawn the pillars.

You should take one pillar from the start. The next one when the rocks stop falling until none are left. If you are lucky and she's low. Then you can finish her off with your odin power (the spears) and the thor power burst (dont attack with it just activating it close to her will also damage her).

Otherwise if she still has a good chunk left you'll have to reflect the shield once more followed by the hero powers.
