It would appear that the rules are contradictory on this point, because they say:
However, in the next section it says:When an attribute score reaches zero, you are broken. You collapse to the ground and lack the strength or force of will to carry on. Exactly what it means to be broken depends on what attribute has been depleted:
Further text (mainly in the Talents) is quite clear when it is stated that they help a character get back to their feet when that character is broken by any of the four attributes, reinforcing the assumption that being broken by all forms of Misery result in falling over.If you’re broken by Fear, however, you can flee to a safe place if you can do so without rolling dice.
This is easy enough to figure out in context and even houserule if needed, but for those of us with rules-lawyer players, I think the text might need to be made clearer.
If the intent is to allow characters who are broken by social interactions to stay on their feet (but otherwise be unable to act), please make this clearer in the text.
Examples of sections which should be changed to say something like "if the broken character is prone" are on p53 (Getting Someone Back on Their Feet), p57 (Orc Talent), p60 (Path of the Hymn Level 1), p63 (Path of the Companion Level 2), p123 (Blood Bond).
Obviously the "Broken" section on p97 would also need sone tweaking.
Apologies if the post isn't clear. It's 5:30am (sleepless toddler).
