The real power source in Odin Valhalla Rising is the codeex. Every piece of gear, rune, seal stone, and summon that you equip gets registered here, providing passive bonuses to your character. This means you can scale your character effectively without needing to hold on to every item permanently. Before dismantling anything, ensure you've equipped it at least once to avoid losing those valuable stat gains.
