Brothers In Arms: Skellige Witcher 3: Wild Hunt Quest
Suggested level: 22
Group: Main Quests
Location: Skellige
You'll get this quest after completing the "Ugly Baby" quest. If you want to complete it successfully, you have to finish it before you travel to the Isle of Mists.
Nowhere in the world can one find warriors braver than those born in Skellige, and thus Geralt set off to those isles in his hunt for allies to stand with him against the Wild Hunt.
Quest stages of Brothers In Arms: Skellige
1. Help Hjalmar with his expedition to kill the giant of Undvik.
To help Hjalmar you must complete "The Lord of Undvik" quest. If you saved Folan and Vigi during this quest, they will also go to Kaer Morhen.
2. Help Cerys unravel the riddle of Udalryk's madness.
To help Cerys, you must complete the "Possession" quest.
3. Help resolve the matter of the succession to the Skellige throne.
To help resolve this matter, you must complete the "King's Gambit" / "Coronation" quests.
4. Talk to Cerys.
After completing the "Possession" quest you will find Cerys in one of the rooms on the upper floor of the Kaer Trolde castle. When you enter the castle, instead of going left to the big hall (where there was a party), go right and up the stairs. Cerys will not go to Kaer Morhen, but will send her best warriors.
5. Talk to Hjalmar.
Whether or not he becomes the king of Skellige, Hjalmar will gladly go and help you in Kaer Morhen.
6. Talk to Crach.
Crach cannot leave the islands and will not go to Kaer Morhen, but if you have helped his children, then he will give you a relic steel sword - Winter's Blade.
7. Talk to Ermion.
Upon request, Ermion will agree to go to Kaer Morhen without hesitation.
8. Quest completed.
In those days everyone in Skellige was thoroughly absorbed with the matter of the succession to the throne, so Geralt had his doubts he'd find anyone at all to answer his call. Yet he did not leave the isles empty-handed, for his true friends did not let him down.
