Boss Order:

1. Odin - The Allfather
2. Hagalaz - The Storm Jotun
3. Isa - The Winter Jotun
4. Kaunan - The Fire Jotun
5. Fe - The Cave Jotun
6. Jera - The Nature Jotun

Want to thank especially two people for incredible boss strategy: PSCHARFF Fe (Cave Jotun) For movement and hitting with hammers and speed at his right side. Also how to finish the boss with arrows on pillars and PSCHARFF Jera (Nature Jotun)
Jera has a soft spot where you can spam speed and hammer. and Low_Life for Isa(Winter Jotun)
When Isa is near the wall he tends to stop before running so when can spam speed and hammer. and Low_Life Kaunan (The Fire Jotun) Good strategy for when to hit speed and hammer. Bombs right before boss and especially using arrows right after he is landing on his head.
