Is there any info on what the stats do? Like Deception, Survival, Brawn etc.
In certain scenes and after certain choices the there will be a skill check. The skill check adds your stat to a randomly generated number (I believe it is between 1-8) and the outcome depends on if you beat a preset difficulty number. The scene will play out differently depending on if you pass or fail.
For example: Jezera catches Rowan doing something shady and you choose to lie to her about what you are doing. The game makes a Deception based skill check. Lets say the difficulty for this check is 7. If you have no points in Deception then the game will roll a random number between 1 and 8, if you get a 7 or 8 you pass the check, not super great odds. But if you put a couple points in Deception those will add to your roll. For example, with 2 points you would now succeed on a 5 or higher, its now a 50/50 shot.
When a skill check happens you will see some text pop up in the top left of the screen. It will say something like "Skill Roll Deception: Success 7 Vs DC: 7" or "Skill Roll Deception: Failure 3 Vs DC: 7." The Success or Failure number is your total (random number + skill) The DC number is what you needed to pass.
If your not sure where to put you points to start, you wont regret focusing on
Combat,
Survival,
Stealth, and
Diplomacy. However you will eventually want have some points in everything, because you will run in to every kind of skill check. Also note that you can can buy permanent skill bonuses from Cla-Min's caravan with your personal gold at 250g a pop.
