And it should go without saying that the boost should be active only while sitting, and weak enough to not be a substitute for Invulnerability.
You think that campfire giving same "buff" (using area effect) that currently sitting down does (2x maybe, I rarely sit down ) breaks the game? I have not crafted any campfire so dont know if there is resources used or are they limited in other way, but the "balancing" could be from there.
