God of War: Ragnarok - Jotunheim Collectibles

When you first visit Jotunheim with Atreus the completion will always be 0%. Don't worry, collectibles with Atreus doesn't count towards overal percentage, so you can even miss them. You will not be able to return to some locations, but since they don't count, no worries.

Ironwood

This is where you end up with Atreus at some point of the story. Nothing you pick up here counts towards overal percentage, nor it counts for trophies.

• Lore 1/1: The Tree [Doesn't count towards 100%]
  Location: When you are at the point where you defat some flying enemies, and the girls is across the river (on map that is the area directly on the upper-right part of letter D in "Ironwood" letters), climb the edges and destroy the object in front, under which the lore lies.
• Legendary Chests 1/1: Rampaging Ibex (Runic Summon) [Doesn't count towards 100%]
  Location: After getting Lore #1, you will go northeast of "Ironwood" letters if you look at your map. You will swing soon, and after you do just continue forward and you will see the chest (ignore the ledge on the right)

Vimur River

This is where you end up with Atreus at some point of the story. Nothing you pick up here counts towards overal percentage, nor it counts for trophies.

• Legendary Chests 1/1: Runestone Refinement (Accessory)
  Location: Northeast from the "Vimur River" last "r" letter you will see this chest on top of the tree stump on the right. On the left, almost directly across this chest is a ledge you can climb onto. Do that, and follow the path to reach the chest.

Iđi's Sinkhole

This is where you end up with Atreus at some point of the story. Nothing you pick up here counts towards overal percentage, nor it counts for trophies.

This is where you climb down to get rid of 4 nests during story. At the end of this area, when returning back from it, just before climbing the chains up you will be battling some tougher enemies, and one will drop Sharpshooter Stare Bow Ability. I don't think you can miss this ability, but I want to mention if anyway.

• Legendary Chests 1/1: Runic Potency (Accessory)
  Location: When you're inside the main cave room from where you can climb onto few ledges, the room with the big red flower, face towards the small ledge you can climb, but climb the left upper ledge from that one, go all the way straight and fall left at the end.
• Lore 1/1: Paints
  Location: When you're inside the main cave room from where you can climb onto few ledges, the room with the big red flower, face towards the small ledge directly across the mentioned flower, climb it, go left, and left again after jumping over. At the end of this road is the lore.

Angrboda's Treehouse

Finish A Stag for All Seasons favour to get Pouch of Yggdrasil Seeds Key Item, which you need to reach some areas you can't otherwise. This is one of them. Activate ih when traveling after touching Mystic Gateway.

• Nine Realms in Bloom 1/1
  Location: West side of the area through the cave.
