Almost all realms remain open after completing the main story through beyond ragnarök except asgard which stays locked. Access sanctuary grove and mist fields for fresh exploration opportunities that unlock new dialogues and challenges. Complete remaining favors for unique rewards, hunt down berserker king hrolf and other optional bosses for powerful gear upgrades

Good to know about collectibles: 47 favors total 38 artifacts and 48 odin's ravens spread across the realms, none of them missable so take your time. Maximizing weapon and armor stats becomes important here since youll face tougher challenges like the valkyrie queen gná

Tip: make sure to revisit previously explored areas, as some locations reveal new paths and secrets that weren't accessible during the main story. Everything except asgard stays available so you can tackle challenges at your own pace without worrying about missing content
