I folow the guide on 'Gamerguides.com'. But after multiple try, i still can't access 'Two-River's Field'. This is boring... Thanks.

What does "can't access" mean here? Does the map transition not work (which would be a bug), or can you not find the area at all?

Some world map areas require your party to have certain perception levels before they can be found. Others require specific story events to occur beforehand.

To expand on this: I'm having the same exact problem right now. Playing for the first time, trying to access Two Rivers Field right after leaving Oleg's Trading Post for the first time. I met Remus and continue travelling along the correct route, but Two Rivers Field just won't pop up on my map, doesn't matter how many reloads or how often I travel along the path.

What's even more strange is that even with auto-success for ALL PARTY SKILL CHECKS enabled in Bag of tricks, the location still won't show up.
The ONLY way I've gotten it to show up is via Bag of tricks - Reveal all reachable map locations.
But since that also reveals pretty much everything else on my map, I really don't want to use this solution.
What's happening here? Kinda frustrating, tbh.

Serves you right for following some janky guide instead of reading what the game tells you, I say.
Even from the perspective of grinding some extra exp it's wrong.

Ah. You. I've read quite a few of your posts here. Fascinating stuff, pretty helpful and thus appreciated.
Now, with that said, I see the foundation upon which the comments about your presumed lack of social skills are built upon.
My dude, you may have 1500+ hours in this game and all that, but you didn't contribute anything of use to my problem, but rather chose to act as one of those awful gatekeepers every niche interest seems to have. If you can't be nice, than at least be helpful. If you can't do neither and only want to exhibit a lack of politeness and dignity, you're wasting both of our time.

I wouldn't call it lack of social skills. More like low tolerance. You quite literally have points of interest already marked on the map, It's not rocket science to visit one of them. And I already did help by telling you to read what the game says instead of following a janky guide. Even more so I did write a sufficient guide on beating A1 in my unfair guide. More help would be assuming direct control and just playing for you.

At a guess, this is what is going on. It will unlock at a later time.

1. If something in Kingmaker requires a perception check (or a trickery check for that matter) it can be redone after each level-up if you increase your perception (or trickery) skill. So... level up and come back?
2. Every party member rolls a perception check, thus it is useful to have the highest possible perception on most of the party members.
3. There are classes that are better at perception checks. An Inquisitor comes to mind.
4. AFAIR it is all explained in the in-game encyclopedia.

In case anyone interested in the same topic turns up here, I've found this on reddit. It satisfied my curiosity regarding the underlying mechanics rather well.

----quote:
I tried leveling up and it always failed if Perception on all characters was lower than 8 and always passed when it was 8 or above. And raising Perception to 8+ was giving a success even without leveling so the roll, if it existed was not reset. There is no roll, just flat Perception requirement.
Also another proof - setting all skill checks to auto pass in Bag of Tricks does nothing for discovering hidden regions. It's pretty obvoius why it doesn't work - there is no skill check.
[...]
I also think that they must have changed how regions are discovered in some patch because I'm 100% sure that when I played for the first time, save scumming was working just fine.

@InEffect: I've read some more of your build guides; again, great work, this will help quite a lot if I ever get out of the FOMO-pit (so many great classes). I also skimmed over your unfair guide. It's a good guide with lots of useful information which I'll put into effect (almost-pun fully intended. Do you find it as hilarious as I do? No? Oh.).
That said, it's a bit rash of you to assume I've read it or even known of its existence, especially since it is neither a sticky, nor linked in your build overview and you didn't mention it in your first post. The search term "unfair guide" isn't really something I'd relate to my posted question, either. Generations of vidya have trained us to always check the surroundings first and the obvious quest marker second. So far, I'm rather fond of the fresh way Kingmaker handles that. You could have used your post as an opportunity to give someone who's interested in the same niche game you're interested in a friendly heads-up about how Pathfinder: Kingmaker differs from the vast majority of games in that it's not only okay, but rather encouraged, to do the main quests asap, because of the whole time mechanic.

You seem to have completely missed the point of my original post. I didn't ask whether or not I'm on the right track, exploration-wise, but rather how the mechanics for finding hidden locations on the worldmap seem to differ from what the game tells the player. It seems to consist not only of a simple perception check (since that would be automatically passed via my mentioned cross-checking via bag of tricks), but rather a combination of that check and a minimum threshold (which is mentioned nowhere and is exactly the piece of information I was looking for). Other users were more on point with their contribution and managed to behave in a non-passive-aggressive manner.
I'm sorry to hear my question triggered your low tolerance for whatever it is you don't tolerate. Since you didn't answer the original creator of the post who had the same question, you seem to understand the concept of not participating when you find an inquiry difficult to tolerate. Since for whatever reason you felt compelled to chime in now, let me remind you that you were and still are absolutely free to just ignore this thread and live your life. To quote the great Ricky Gervais: "That’s like going to a notice board in the middle of town, seeing a sign for guitar lessons, and yelling, “I DON’T WANT guitar lessons!” Well, it wasn’t for you."

I don't feel qualified to make guesses about the objective quality of this or that internet guide, but you didn't elaborate on (or even touch upon) why said guide would be regarded as janky. It did occur to me that this specific guide doesn't use your build contributions like e. g. the neoseeker one does, but since I know fuck-all about you, I'm inclined to give you the benefit of doubt and not assume some petty ego-related reason.

I'm thinking perhaps in dealing with you it's best to take a perspective like many avid readers do when it comes to H. P. Lovecraft: Separate the craft from the creator. Thus, I acknowledge your work as the valuable addition to the meta it really is, and bid you a good day; it has been entirely unpleasant conversing with you.

@Pangaea666: It doesn't seem to be connected with story events, but your input is appreciated.

@Grrymjo: I did read the In-game Encyclopedia. The game just doesn't explain it to the player that there is a minimum treshold and not even a natural 20 gets you the location on the map if none of your active party members has a perception skill above that threshold. That's the part which confused me and made me think it might be a bug. Thank you for your input, though. I appreciate it.

If you are interested how hidden locations work - just say so. Because your post pretty much read as 'I follow a guide and it doesn't correlate with my in-game'. IMO that would be a question for whoever wrote a guide.

As to how checks work:
You get 1 check per character per level for perception(including spotting traps) and trickery(when used to open locks). If you've missed the check - tough luck, try next level or change party composition to maybe have some better luck next time. That would be the reason it's highly advised to have at least two high trickery guys for the chests(it's mildly annoying to click on a chest, fail a check and be forced to load who-knows-when made save, cause, lets be honest, we all do scum skill-checks) and perception on as many guys as you can afford to have and preferably have it rather high at that.

This is more of a tangent, so sorry about that, but sounds like you are playing for the first time. I'd strongly advise to not use guides or walkthroughs, except maybe look up stuff you are unsure of there and then in-game. Previously, in other games, I've made the mistake of quite avidly reading wikis and guides while playing the game, redoing quests to get the ideal outcome and stuff like that. But it kinda ruins the experience. In this game I basically just dove in and played, and what happens happens. Kinda helps that the wikis are very bareboned for this game, oddly enough, but I made a conscious decision to not look up stuff -- well, except glance at some guides here. On normal difficulty, going with a single class is fine, I did it for most of my characters. It's on hard and to a lesser extent challenging the game becomes a reload inferno because one (normal) roll will one-shot your characters in the early game. With "luck" they get perma-death too, because two hits land.

I found it a lot of fun to simply explore the map as I went along. Looking at that giant world map and all its locations, and slowly expanding the visual field and discovering more locations. Throughout the game, more locations popped out due to the story unfolding, or in rare cases because of perception checks and suchlike. It made that first time a lot more enjoyable. Starting a second playthrough now retains some of that (can't remember everything ofc), but it's not the same, because I know what happens where and in roughly what sequence. When relying on guides and walkthroughs, much of that magic is lost. Like the saying goes, you can only play a game for the first time once.


[As an aside, I did try to put in a ton of work for the Gamepedia wiki, but then the "fine" folks at Wikia and Gamepedia wanted to shut it down and yelled at me and called my work sabotage, and all sorts of other crap in their discord server, which caused me to abandon work for all their bloody wikis. And I had planned a whole fucking shitload of work. Always sucks when you get yelled at for trying to help, and various fake allegations are thrown in your face. By their staff. Fuck that shit. Sigh... :( Looks like the ruckus made them postpone the immediate shutdown, but with the threatening axe hanging over its head ]

Following a recent post on reddit, it looks like certain areas will only appear after reaching a certain number in your perception skill checks; for two rivers field it's 8, and it's also 8 for the old oak. I know in the past it used to roll for the check, but this doesn't happen for these locations (it might still for other locations). I've tested this myself, under 8 perception it will never show up (I probably did 20 reloads of that road to test so it's not 100%), run past with a character with 8 perception or more in party and it will show up 100% of the time, though; pretty strong indicator for it being purely based on a certain number in perception.
