Well, it took awhile but here we are, the guide is 100% complete! Big thank you to all who've helped and participated in the completion of it, thanks to Warhorse for fixing some bugged entries and thats it for now! If we get some new entries with the 4th DLC I'll see you here again!


Cheers!

There are a few points which I'd like to clarify before we start:

1. There are several MISSABLE Codex entries, meaning that if you don't get them from doing or saying/asking something specific you won't get them. They will get [ * ] symbol before them, so you can use ctrl+F and then search for * to see them and hopefully not miss them. Keep in mind that doing all side quests and tasks, and exhausting all dialogues will prevent you from missing most of the missable entries. NOTE that there's a random encounter in Kuttenberg region which unlocks two Codex entries, but to unlock them you have to pass a hard Scholarship skill check. So make sure to level up your Scholarship, the best way to do it is as follows:

Originally posted by alleyezonme:

• Get your Alchemy to level 16.
  
• Aquire Secret of Secrets perk.
  
• Brew Henry's Fox potions[kingdom-come-deliverance.fandom.com] for increased experience gain.
  
• Visit a Scribe or simply collect all books which you can find.
  
• Put on your spectacles and find a comfortable spot to sit down.
  
• While Fox's effect active read all the books that you have, but haven't read yet. Read both lore books (the ones where you can turn pages) and skill books (the ones where you spend time reading), learning crafting recipes and sketches also gains Scholarship experience. Exhausting some dialogues also levels up your Scholarship.

2. Throughout this guide you will see references to different aspects of the game, such as main quest, side quest, task, «name of» point of interest, perk in a certain skill tree etc.
I highly recommend PowerPyx's walkthrough[www.powerpyx.com] not only because it lists all main quests, side quests and tasks of the game, but also because you can see which of them are missable and, moreover, how to activate some of the not-so-obvious ones.

3. If you want you can use different interactive online maps to find points of interest [POI] mentioned in the guide. However, if you haven't already done so, I highly recommend you aquire the Explorer perk in the Scholarship skill tree. What it does is it removes all fog of war from the map and allows you to see all POIs there are, as well as fast travel points, hunting spots, merchants and every other thing that can be marked on the map. It's probably a bug, but I got this perk while still in Trosky region and when I got to Kuttenberg region I had all fast travel points unlocked and on top of that all Codex entries in Locations category which were tied to specific fast travel points in Kuttenberg region got unlocked automatically. My preferable way of leveling Scholarship can be found above in a quote.

4. It's also important to remember that there are a few Codex entries which have more than one way of unlocking them. The best example of it is the Burial entry in Society category. I've described the way I got this enry on my 3rd playthrough, BUT there's a way of getting it early (during my 1st playthrough I somehow got it early, but I don't remember exactly how or when, but again I'm 100% certain that it was much-much earlier than in Sedletz Monastery). The same goes for many entries that require you to visit some non-unique places for the first time. For example, if I wrote that you unlock an entry by visiting a carpenter in Troskowitz, it means that it's the earliest way of unlocking it, however there are other carpenters in Kuttenberg and in other places and thus there are other ways of unlocking that entry.

Legacy of the Forge introduced three more Codex entries in the following categories: Thanks to CzechKronner for pointing them out before I found them myself.

General:
Astronomical clock – before you even officially start the DLC if you go to the main square of Kuttenberg (fast travel point just north of Hangman’s Halter Tavern) you’ll get the ALT-look prompt at the bottom of your screen. Press the button to get Henry say something about the clock and unlock the entry. Throughout the DLC there’ll be at least three instances for you to take a look at the clock using the ALT-prompt, the last one being after you complete the DLC so you won’t miss this entry.

Society:
Guild Life – automatically unlocked during the last Ragman’s special quest. To trigger this quest you need to complete several sets of thieving contracts (Blacksmiths’ Guild activity with a hand marker on it). If you have any difficulty with completing these I refer you to this guide by 0verflux.

Craft:
Papermaking – automatically unlocked during the last Ragman’s special quest. To trigger this quest you need to complete several sets of thieving contracts (Blacksmiths’ Guild activity with a hand marker on it). If you have any difficulty with completing these I refer you to this guide by 0verflux.
