In Judgment, Demon Stamina is a useful early game Ritual. It is cast via a Dark Altar.
Demon stamina is cheap and long-lasting enough that it can be cast around the clock. For the duration of the ritual (960), survivors will enjoy a -1000% reduction to their sleep needs rate - meaning they will simply not need to sleep, at all. Without the need to go back to bed, the survivor's overall productivity can skyrocket, especially if coupled with the Soul Harness ritual.
