You can build a little brick house.
- Fullness bonus 50%
- Sleep bonus 100%
- Special bonus: the hunger and thirst never go up (it go up, and then go down automatically)(that's actually the Fullness bonus from above. Moreover, hunger and thirst do go up, it's just slower, as it should be, given that you're getting hungry twice slower)
Need(Survival skill lvl 11):
- Brick house x1
- Mechanical skill +?(doesn't make sense, as you already reached the Max lvl)
- The nails can be a problem if you want to build the house away from towns.
- It is a good idea to use a UAZ/KamAZ/BelAZ for the bricks
- You can also build the house directly inside a town on top of a building with a lot of bricks & wood, so that you avoid fuel costs of transporting 50k bricks outside of town.
