There are 35 Nornir Chests in God of War Ragnarok, four of which can be found in the realm of Midgard. Players can get to most of them when they first visit the realm during the game's ninth chapter, though will have plenty of chances to return later on if they miss them the first time around. This bodes well, as finding Nornir Chests is the only way to boost Kratos' maximum health and rage in God of War Ragnarok.
