Descent into Midnight
Rest Requirements: House Rule
For the purposes of this game, 8 hours of rest includes time spent on watch. As long as the group is not attacked or otherwise disturbed, if they have made camp for 8 hours and slept their share, all spell-casters are assumed to have regained their spells.
This rule is under the assumption that you are in a party of at least 4 characters who each take a 2 hour watch.
Rules have been modified from gnunn’s page to fit this campaign.
