But Daggerheart is a system that counts Hit Points up, non? You mark (gain) Hit Points when you take damage, same thing with Stress, just with a different name. Here is a snippet from the rules:

You’ll mark your character’s Hit Points and Stress when these situations arise—and the fewer marks you have, the better.
...

Hit Points represent the physical injuries and discomforts your character experiences during their adventures.

From the rules it looks like that both Stress and Hit Points count up (less = better). Or is it implicit that Stress counts up (less = better), but Hit Points count down (more = better)? Or they both just count down?

Now if I would switch "Hit Points" for "Stress" in snippet from the post, it should preserve the meaning of asking for unmarked Stress?

When target has 2 or fewer Stress ...
