Lethebane

Even those with only a passing interest in spirit magics eventually learn to develop a basic awareness of -- and control over -- dreams and sleep. Those trained in the lethebane skill will gain resistances to being forced into magical sleep, as from the sleep and drowse spells. Furthermore, a mage so gifted can use the 'wake' command to simply awaken any save himself caught in forced sleep; used this way the ability will assist against even physical sources of enforced sleep, such as waylay. The scholar should take heed, though, that while this might lift the immediate unconsciousness, it will do little to fix the underlying cause of the unnatural rest.
