This is a guide for deduction portions of the game, as well as all achievements. Some dialogue (such as the conversations with "???") have very limited choices and no penalty for wrong responses so I have not included these. I referred to the Chinese steam guides when compiling the achievements/endings lists.

Note that after completing the game you can jump to specific sections within chapters, meaning you can go back and pick up any achievements / endings / knowledge that you missed. These chapter sections are marked in this guide.

There are 3 collection based achievements:

• [Achievement] Destined Endings (Collecting all endings): These refer to the bad endings you get when you lose a case.
  There are 29 endings, marked by [Ending] and numbered according to the order they appear in the in-game ending list you can view after completing the game.
  
• [Achievement] Traveling Scholar (Collecting all general knowledge):
  There are two easily missed pieces of knowledge, "Slag" in Ch. 3 and "Burden of Proof" in Ch. 6. These are marked by [Knowledge]. I've also marked the other missable ones I know of.
  
• [Achievement] Learned Sage (Collecting all historical facts):
  There is one easily missed Historical Fact, "Mixed Court" in Ch. 6. I've marked the missable facts I know of with [Historical Fact].

At this time it is not possible to collect all the general knowledge, as there are 6 entries from the DLC which has not yet been translated to English.
