Sleep is a restorative process through which adventurers can regain lost health. Dreams are a common experience for all sleeping adventurers, a gift of the Goddess Valnurana. All adventurers will eventually grow tired and need to sleep after a time, the exception being those adventurers who have reached or surpassed level eighty, at which point both sleeping and eating become superfluous.
Putting an enemy to sleep is also a battle tactic for saavy adventurers. This may be done a variety of ways: by inflicting the venom delphinium or by use of the hourglass tattoo. For this reason some adventurers voluntarily suffer from from insomnia, a condition that will also prevent sleep. Adventurers may also ingest the kola nut to ensure waking quickly once falling asleep.
