Quest stages of The Mask of Diplomacy
1. Report to Flann
Travel back to Clogher. When you get there you will find that Flann did not listen to Barid's warnings and did not pull back. After a while he will see how wrong he was because Eogan's troops will start attacking.
2. Survive Eogan's attack
Start eliminating the enemies attacking you. You can use the ballista standing nearby for this purpose.
After a while a group of archers will come from the right side. Get rid of them.
Once you get rid of all the enemies in this part of the village, a new objective should appear telling you to help Flann and Ciara. This can be a bit confusing as they both might be near you. Just run towards the quest marker, which is at the other side of the village and start eliminating Eogan's soldiers.
If you manage to defeat enough of them then the rest will flee and the attack will be repelled.
3. Find and speak to Bárid
Find Bárid. Unfortunately, you will find that he has been mortally wounded. His funeral will end this quest and you will receive another - "The Wages of War".
After completing The Mask of Diplomacy you will get or will be able to get The Wages of War.
