Skip Sleep
Skipping Sleep is when a character attempts to alter their rest cycle from day to night or vice-versa, or simply push themselves beyond the normal cycle when they would need rest/sleep. The character will push their physical limits, with it getting progressively more difficult as time goes on. There are chemical/botanical and mystical stimulants that can assist with this.
Attempting to Skip Sleep may be affected by wounds, environment, mystical powers, also Deep Sleeper and Light Sleeper may affect this..
