Location: Hidden Chamber of Odin, Light Elf Shore, Alfheim.
Olrun shares a lot of similar telegraph attacks as her sisters. Her attacks include the following:

It’s better to attempt this fight after getting the Blades of Chaos and unlocking some of its runic attacks. That way, you’ll have four runic attacks at your disposal. It will be hard to go head-to-head with valkyries using normal attacks so evading their attacks and counterattacking with runic attacks is a reliable way of removing a good chunk of their HP quickly. You can still perform normal combos as long as you don’t get too greedy and you prioritize reacting properly to her attacks. Also, save your Spartan Rage as a life saver, preferably to recover your HP. While in Spartan Rage, you still have to avoid being greedy as sustaining damage will deplete your rage meter a lot quicker without recovering your HP.

After the battle, you’ll obtain the following items:
* Olrun’s Helmet (legendary quest item)
* Asgardian Steel x2 (legendary resource)
* Perfect Asgardian Steel (epic resource)
* Ivaldi’s Corrupted Mind (epic enchantment)
* Waist Guard of the Valkyrie (epic waist armor)
