We'll start out with a discussion of WHAT this guide covers and HOW we can go about uncovering Thronebreaker's secrets.

This guide will be focused on tangibles; Gold, Wood, Recruits, Morale, and Card Unlocks. We might mention intangibles, but they are not the focus of this guide. What do I mean by intangibles? As an example, in Mahakam (map 3) you might or might not have a feast thrown in your honor at the end, but all that changes is the background screen and a few lines of dialogue... nothing else.
Thus I do not make note of it having happened or not. Additionally, if there is no choice in the matter, I will probably not record it. Eg. I will not list every single stump you can click on for gold/wood, but I will include morale changes just because they can affect other choices and I'll try to record every “true” battle which resets your morale for the same reason. I won't be reporting puzzle nor story battles unless they involve choices because (as a general rule) they do NOT reset your morale. And if nothing is listed after a choice then there are no known consequences... yet

I record a "+Evil" everytime the game says "You choose one evil over another..." which seems to mean that there will be consequences for the decision in the future. If there is no "later on" comment to go with the +Evil tag then the consequences are not known. Please leave a comment if you DO know what they are. I've not been consistent in recording each and every note and letter that is missable, but I have recorded a few spots with the +Letter tag, mainly on paths you'd otherwise avoid because of bad outcomes. TODO: go back and try to find all missable letters and notes

Oh and just a general bit of advice; -Morale when morale is already "Low" has no effect, thus you can save a bunch of morale reducing optional encounters till the very end of the map then do them all at once for only -1 or at most -2 Morale. Save a Wayshrine or two to fix the morale before going into the next chapter as well.

Likewise, since story battles are impacted by morale, but do not reset morale; you can get two or more battles' benefit from one +Morale if you plan it out right.

Next, Thronebreaker has a rather strict save policy; no manual saving other than to exit the game, and the one save slot per game it does have is overwritten immediately following any choice thus preventing you from exploring alternate options without replaying the whole game... or at least that was the designers' intention. We actually can manually make manual saves, but it isn't a straightforward process. First we need to know where the saves are stored:
C:\Users\NAME\AppData\LocalLow\CDProjektRED\Thronebreaker\SaveData
-or-
%USERPROFILE%\AppData\LocalLow\CDProjektRED\Thronebreaker\SaveData

In order to manually save then, we'd simply copy this folder to eg the desktop and to "load" we'd overwrite the contents of this folder to restore a previous save. Just be aware of WHEN the game writes to this folder; you don't want to restore a save, have the game overwrite the folder, and then try to load and wonder why your loaded game is not the save you wanted.

If you want to restore a save from a different chapter than you are currently in, I'd reccommend exiting the game first, otherwise things can get buggy

End of Tutorial, from here we have three different paths to explore before hitting the Main Mission objective; Lord Clayton's Estate. The path this guide will follow is: NE, then West, then SW, but you may do them in w/e order you prefer. You might want to collect everything you can while avoiding the battles in order to first buy the camp upgrades that give gold and/or a recruit after each battle. If you pinch every gold penny, you can actually (just) afford both camp upgrades before doing any further battles

What you lose:
1x Count Caldwell
2x War Wagon
5x Lyrian Arbalest
3x Regiment Drummer
2x Rivian Pikeman
2x Wagenburg
2x Field Medic

When fighting elves on this map; neutral Morale is ideal. This is because at high morale all of your units are considered "boosted" and thus Elven Archers will do 6 damage instead of 2. While at low morale all of your units are considered "damaged" and are thus able to be destroyed by Elven Swordmasters who destroy one damaged unit every turn. There is usually only one Swordmaster in any given battle's deck tho.

Here are the rewards for each tier of reputation w/ Brouver Hoog and Mahakam:
Low reputation = 0 Recruits, 2 copies of each card
Medium reputation = 48 Recruits (might be a random amount) 4 copies of each card (+Letter later on)
High reputation = 104 Recruits (might be a random amount) 5 copies of each card (+Letter later on)

It should also be noted that these cards cannot be crafted; you are stuck with the number you get.
Additionally, I'm told you can only get high reputation by turning in the Zigrins and thus losing Gabor. But, if you want to maintain medium reputation the following ought to do it:

Bad Points:
- Refuse to help look for the 40 missing dwarven youngsters to keep both Rayla and Isbel
- Attack the Nilfgaardian arms caravan for the Card Unlock
- Give the true peak measurements to keep Eyck
- Don't turn in the Zigrins to keep Gabor

Good Points:
- Accept Eudora's offer
- Kill the dragon
- Solve the "curse" of Black Brook Vale (by recruiting Barnabus)
- Hand the Rivians in the mine over to the dwarves
- Return the Vidmar treasure to the elder-in-chief
- Intervene and defend the foreman at the memorial
- Forego vengeance on the Nilfgaardians who ordered the avalanche

Now if, like me, you've some how managed to miss getting the "Burn After Reading" achievement by this point, here is a quick and dirty way to get it. Exit out to the main menu, tab out of the game, find your save folder, and open this file in a text editor:
CAMPAIGN_SAVE_NorthernRealms_Slot_0_Snapshot_2147483647

For every "CollectibleLetterEntry" line that has an <m_Status>0</m_Status> just edit it to have a value of 1 like so:
Save the savefile, load it up, read all the new letters and notes you missed, and the achievement should pop up. Oh, and always make a backup of your saves before editing them just in case you mess something up

This guide was built upon the same framework as I did for The Banner Saga; if you enjoyed Thronebreaker, you might enjoy that game as well.
