Begin the council
After the cutscenes, head to Kaer Morhen keep. You can speak to the allies who came.
Enter the keep and begin the council.
Choices to be made
During the council, you have some choices.
The first one is choosing between witchers’ traps and the potions. The traps are explosive traps and only affects the Wild Hunt.
If you choose potions, you will get a Superior Swallow and Thunderbolt.
The second choice is between patching up the wall and clearing the armory.
If you patch up the wall, there’ll be less waves of monsters. If you choose to clear the armory, witchers are armed with shiny silver swords.
It all depends on your preference.
Exit the keep
When you’re ready, exit the keep as you prepare to go to the woods with Lambert.
Close the portals in the woods
After the arrival of the Wild Hunt, you need to close the portals in the woods. There are 3 portals in total.
You have invisibility if you don’t fight.
The portals’ locations are shown in the map.
To close the portal easily, just throw a dimeritium bomb at the portal, or use Yrden.
Stay away from the hounds to avoid detection. The best way is to go from behind.
After the portal closes, your invisibility disappears and you need to kill the Wild Hunt warriors and hounds.
Continue the same process for the two other portals.
More Wild Hunt soldiers will appear and as Geralt gives a signal to Triss to use her fireballs, she didn’t respond.
Run to Triss
Now, you’ll need to control Ciri. You have to help Triss.
Go towards her and kill the Wild Hunt monsters in the area.
Return to Kaer Morhen
Triss then resumes her duty in shooting fireballs. You have to return to Kaer Morhen with Lambert.
