ConsulCaesar: I am guessing you refer to "Reason of State":
https://witcher.fandom.com/wiki/Reason_of_State Just so it is easier for you to avoid spoilers, here are the requirements from the wiki:
Reason of State is a secondary quest in The Witcher 3: Wild Hunt.
This quest is available during Act III, but has a number of prerequisites from earlier points in the game:
* Complete A Deadly Plot. This means doing Triss' quests, A Matter of Life and Death and Now or Never to get this one.
* Obtain and complete (or fail) An Eye for an Eye and Redania's Most Wanted. See the notes section for further details.
* Bribe Dijkstra with information about the Nilfgaardian Emperor Emhyr, rather than sway him by force during the main quest Blindingly Obvious.
Note: the decisions during this quest, as well as whether to complete it or not, will affect the circumstances of the game's ending.
Note: this quest will fail if not completed before starting On Thin Ice.
ConsulCaesar: Thanks, I think I locked myself by giving the something to Radovid. If I ever play this again I'll not to do that. Cheers!
