Assassin's Creed: Valhalla

Potion of Blood

By
Scott Peers

This quest begins immediately after Foothold in Connacht. The morning after the battle for Cashelore Castle has brought dire news: half of Flann’s army have been poisoned. Eivor and Ciara must find a cure before it’s too late.

Potion of Blood, Wrath of the Druids.

Follow Ciara and Speak to Deirdre at Asfinn

After you’ve spoken to Barid and the cutscene with Flann ends, you’ll need to meet Ciara at the stables. Ciara has a mysterious friend named Deirdre who will be able to provide an antidote to the poison. Follow Ciara to Asfinn and meet Deirdre. When you’re near to Asfinn you may need to use your bird to locate the exact area where the roundhouse can be found. When you enter the house a cutscene will begin, during which Deirdre explains that the Children of Danu cult is behind the poisoning. Deirdre can provide a cure for the poisoned soldiers, but Eivor will need to take a shard of amber from one of the Children of Danu cultists, to be steeped in its owners blood in order to unlock the powers of the amber.

Find and Kill The Wren (Lady Niamh)

Find the Clue at Port Auley

The process of finding The Wren will be familiar if you’ve hunted Order of Ancients members before. You’ll need to find specific clues which lead to more clues, and eventually to the cultist themselves. The first clue can be found near the Port Auley trade post. More specifically, you’ll find it in a building on the coast just north of the trade post. When you enter the building, you’ll see the clue on top of a pile of sacks. Read it to learn more about where you need to go next.

Find the Clue at the Ritual Stone in Lough Gara

The next clue can be found near the ritual stone at Lough Gara, near Rathcroghan, just south of Port Auley. Once you’ve read this clue, the location of The Wren will be revealed.

Assassinate The Wren at Rathcroghan

Once you’ve read the clue at Lough Gara, you’ll be able to track the location of The Wren at Rathcroghan, located just south of where you found the clue at Lough Gara. Be sure to mark The Wren’s location from the Children of Danu menu, then find her within Rathcroghan and take her out. You’ll need to confirm the kill before you can move on, but once done all you need to do is return to Deirdre to complete the quest.
