I sent my companions into missions through table. They finish a quest, but they have increased fatigue. If I know, this can be lowered with rest. The only way, which I know how to do this, is add it into party and rest. But this can be time consuming is there another way to do it?

That is the "free" way to do it, but does take time.

The main way to do it is through the Burrow. Upgrade the Burrow to level 1 and then go to the Burrow and at the main desk (clear in back) you will find a book you can click on, click on it and you can select any person that is not on a Mission, Research, or in your party to let rest in the Burrow. It takes time and costs gold...the more fatigue the have the more time and gold it takes. Once they are done resting you will need to go back to this book to "get them"

I worked on upgrading the Burrow as quick as I could to take advantage of the benefits: less costs, less time, and more "beds" (slots) to rest more of them at the same time.

Thanks, I was curious for what the beds are, but as you wrote, I have to go to Burrow. I'll try it.

But upgrading Burrow is prety costly. Not with gold but with supplies. Did you manage where to get those suplies? There are lot of resources but very little flour or other ingredients to cook supplies. In demo there was plenty in full version they are gone. I buying them from traders. Upgrade cost 250 supplies and when I am outside post and need long rest, it can consume lot of supplies. Sometimes cca 50.

I do make some, but I also buy a lot of them from the 4 people in the Outpost who sell them. 2 in the open area outside the Keep (marketplace) and 2 in the Burrow.
