Quest stages of Potion of Blood
1. Speak to Bárid
Go to the southern part of the fortress. When you get there you will find that some of Flann's men were poisoned and the man who did it will claim that Bárid paid him to do it.
Ciara will decide to go get the cure and will choose you as the one to help her with that.
2. Meet with Ciara at Cashelore's gate / Follow Ciara
Ciara will be waiting for you on the bridge, near the gate you had to open in the previous quest. She will want to visit her familiar druidic healer - Deirdre. Get on your horse and follow Ciara. On the way she will tell you about a cult called "Children of Danu", which is probably responsible for the poisoning.
After some time you will reach a place from where you will have to continue to decide where to go.
3. Find and Speak to Deirdre
Just follow the road south. At some point a pack of wolves will attack you. Get rid of them and continue your way and soon you will reach a place called Asfinn.
Enter the cottage and you will learn what you need to prepare the antidote and how to do it.
This will unlock the "Children of Danu" tree, the equivalent of the "Order of the Ancients" tree.
4. Find and kill The Wren
Use the Children of Danu menu to mark your target. The first clue is:
Investigate the abandoned cottage on the shore outside Port Auley at the mouth of the Ballysadare River in northern Connacht.
When you reach the described place you will find the Note Found in Port Auley.
The clue you find will describe where the next clue is located.
Investigate the ritual stone located on a small island in Lough Gara found near Rathcroghan.
Head south to Lough Gara and find the Note Found Near the Great Stone.
Once you do this, you will find out where The Wren is and you will be able to mark her position on the map.
5. Assassinate The Wren
Head to Rathcroghan and find The Wren. She moves but since you have her marked you should have no problem locating her. Kill her and you will get the Bloody Amber, Note Found on The Wren (a clue about The Ash), and the Objects Found on The Wren (a clue about The Cursed).
6. Take the amber shard to Deirdre
Return to Asfinn and hand over the amber shard. Deirdre will prepare the antidote and Ciara will set out to deliver it to the soldiers. You, in turn, will set out to find another member of the Children of Danu - The Cursed.
This quest will end and you will receive two new ones - "Into the Fog" and "Children of Danu".
After completing Potion of Blood you will get or will be able to get Into the Fog.
