There is none atm, the wikia only has a few and often perk/skill info is incorrect, since it was not updated from the 1.0 live version.

For skills the only reliable way atm is to check them ingame, but be aware that there are quite a few bugs, missleading skill infos.

Here are the current resources i know of:

Just add ( not publicity but i found his video usefull and well made ) ... the video of AirSickHydra on YT if you understand well EN ^^

Remap them completely to what feels most natural to you... sounds obvious, but some people underestimate how customizable these controls are and how much of a difference this can make.

For example, I found the 1,2,3,4 keys for the skills extremely unergonomic due to the fact that you constantly need to use them, and my left hand is used to resting on WASD, so it's quite a stretch to constantly reach for those number keys.

Now with my hand being perfectly used to resting on WASD, I just went ahead and remapped the entire skill keys as follows:

• Skill 1 and 2 obviously are the only ones you cannot improve upon, they are still LMB and RMB
  
  
• Skill 3 and 4 are now Mouse Button 4 & 5, the Forward&Back navigation thumb keys that most "gaming" mice have.
  
  
• Skill 5 and 6, i.e. the skills that come from your armor and Psy Focus, etc, it's A and D -- for assassins, this would conflict with the dodge mechanics, but otherwise these keys are free and I don't plan on rolling an Assassin either way.
  
  
• The Inoculator has been mapped to W, so that now I have all those things instantly reachable in the most comfortable positions possible, and this actually immediately lead to a noticeably improved reaction time and thereby better odds of survival, plus the left hand wasn't as stressed when gaming for longer sessions at a time.

Maybe this way works for most people, maybe it's just me, but whatever the case -- the message is map those features you use the most to keys you are most comfortable with, and it'll make for a smoother, less distracting and less taxing gaming, especially for those longer sessions.

Well, https://guides.gamepressure.com is where I always go first for such things and never was disappointed so far.

You'll find the "guide" for Inquisitor Matyr here:

We also have game devs who include the manual inside the game (when you need an information with the Assassin's Creed games, you find all the commands, even with examples sometimes, and more !).

And you have games where you have to discover. And face poor translation when you have some details. Even translated details for perks unlock suffer very low level of translation.

@KORVOATTANO‍ thanks for the links, it may help several players ;)
