help from djisktra from the battle of kaer morhem

Letho isn't needed for the achievement, but can still be brought along if you complete Ghosts of the Past and, at the end of quest, choose the option to invite him to stay at Kaer Morhen (Vernon and Ves won't like this but it won't affect the achievement).If you didn't find the location though, he'll refuse to help. If you learned the location of Dijkstra's stolen treasure during Count Reuven's Treasure, he'll give you some money.If Cerys was made queen she'll send Hjalmar.Cerys, Crach, Dijkstra, and Emhyr won't come along for various reasons.Since Eredin could trace where Ciri traveled to with her abilities, the duo did not so much flee the Hunt as buy a few precious minutes of time. 'Geralt and Ciri had no choice but to teleport away from the Isle of Mists when the Wild Hunt threatened to attack. Once completed, you can recruit him once you get the Brothers in Arms (Ves will tag along automatically). The Battle of Kaer Morhen is a Main Quest in The Witcher 3: Wild Hunt. You must keep Ves alive during this quest. For Vernon, after completing the main quest Get Junior, go talk to him again to ask what he needs help with and he'll give An Eye for an Eye that you need to complete.As long as one of them becomes the next ruler, you can then ask for help and Hjalmar will go (if alive, Folan and Vigi will accompany him).

Then, during King's Gambit, you must help out Hjalmar or Cerys. For Hjalmar, you must do either Possession or The Lord of Undvik (or both).If you kill her or let her go to Radovid V, you won't get the achievement. For Keira, you must complete all her side quests (see the achievement Friends With Benefits for list) but during her last one, For the Advancement of Learning, you must send her to Kaer Morhen.

He does however offer some help (toward the Battle of Kaer Morhen) if you find out where his treasure is and give him the key.

Zoltan and Ermion are the easiest: as soon as you get the Brothers in Arms quests, you merely have to ask them for their help and they'll head to Kaer Morhen. You did after all know that Dandelion stole his treasure all alonb but kept the information from him.

While not all of them are needed, it'll let you know who you've already talked to.

A good way to keep track is by paying attention to all the Brothers in Arms quests ( Velen, Novigrad, Skellige, Nilfgaard).
