As you play through My Time at Sandrock, you'll gather experience and gain Knowledge Points to spend on various skills. These points can be spent in four Knowledge areas — Gathering, Workshop, Combat, and Social. Each category requires you to perform specific tasks to acquire XP for that specific skill tree. Points are not lumped into a general pool to spend wherever you'd like. 

This guide will outline all of the skills currently available in My Time at Sandrock, as well as their effects. It will also tell you how to respec Knowledge Points should you want to choose a different path. However, there aren't too many available, with some locked at this point in Early Access, so it's likely you won't need to respec too much, if at all. 

Knowledge trees do not become available until you reach Character Level 5. Once you do, you'll be able to find the four skill trees under the Knowledge tab in the menu. It is the lightbulb icon between the Calendar and Album on the right side. 

You gain experience in each Knowledge category by performing specific tasks related to that category.

Each Knowledge area has its own Level to increase independent of Character Level. Your overall level and progress to the next level can be seen in the upper right corner of each category in the Knowledge tab.

You'll see a lightbulb appear to the right of your stamina bar when you have an unspent skill point, and you can see how many unspent points you have by opening the Knowledge tab and looking at the four category icons in the upper left. There is no need to hoard skill points: every level costs only 1 point. 

To spend skills points, select a category, double-click a skill node, and click the Learn button at the bottom of the description on the right. If you double-click a skill you do not want, press ESC to exit the menu entirely, click another category and choose "Cancel," or right-click on the node (though the latter didn't work during my time with the game). 

Here are all of the skills currently in My Time at Sandrock as they are described in-game.

It's unlikely that you'll find the need to respec any of your skills in My Time at Sandrock. However, there is a way to do so if you wish. 

Go to the Clinic in the northwestern portion of the map, near the Game Center, Museum, and sparring ring. Speak with Fang and choose acupuncture, the third option. You'll be able to respec individual categories, as well as all of your Knowledge Points at a single time. 

Each respec costs a certain number of Gols to perform based on the number of skill points in a single category (1 point = 10 Gols). The exact price will be presented when you choose the category, but the more you have, the pricier the respec. 

And that's basically everything you need to know about Knowledge Points, skills, and how to respec in My Time at Sandrock as it stands this close to the game's Early Access launch. For more, head over to our Sandrock guides page.
