Coroc i think that's a house rule. I don't remember a rule about saving to remove exhaustion in core.
Now THAT is a very intriguing idea! I hadn't thought of that. But it makes for an interesting decision point for each player as they have to decide what is and what isn't important to their characters.
I think that were I to go with this idea though... I'd probably make this chart arrangement for each PC as part of their character generation. So rather than letting each player rearrange the chart each time they drop to 0 HP (and thus try and min-max every single situation and slow the game down)
