Shelter
A roof you made
Short answer
Stick shelters and lean-tos keep rain off. They also look like a sign that says someone is here.
Also: lean-to · improvised shelter
How it works
You can plant a small shelter from sticks. It's not a base. It's a pause.
What to do
Use it, then leave or watch.
Don't
Don't live in one on a ridge.
