I've been searching around a bit to see if there are any noticable changes during the night as opposed to during the day, and so far haven't found anything.
I'm fairly sure there's no DS modifier added (as per spell 206). There is a creature that only appears at night (lich Qur'yna (sp) in Old Ta'Faendryl), but so far that seems to be the only change.
Has anyone noticed if there is a hiding bonus or perception loss during the night? And just how long does night last, anyway?
It seems a bit strange to me that the new night mechanics would be solely cosmetic. reg
