Quote:
Structured Time: A fatigued characteristic counts as half its normal value (rounded up) when the character wishes to perform an action that includes a test that calls on that characteristic, or any other uses of that characteristic.
Narrative Time: Any time the character performs a task that includes a test of a fatigued characteristic, that task takes twice the normal time to attempt.
I ask the players to subtract half of it from the XP tab where the raw numbers are, but I think it will be awesome if can happen automatically.
