All the non-humans get 2 less misfortune dice when in darkness or low light situations than humans - however nowhere (that I can find) does it seem to state (or suggest) what penalty acting in darkness should be at.
The racial skills would seem to indicate that the penalty for actions in darkness is probably 2 misfortune dice, leaving the non-humans unaffected, which might be ok if there is further penalty for total darkness - I'd have prefered a challenge dice for total darkness rather than lots of misfortune dice, but since that doesn't work with the racial abilities I guess it'll have to be lots of misfortune dice.
Comments, ideas, anything I've missed?
