Light Sleeper
Prerequisite: Alertness.
          OR: WIS >= 13.
Benefit: Your incredible instincts allow you to remain aware of danger even as you sleep, waking on a hair trigger and ready to respond to threats. In game terms, if you have an encounter while resting, the monsters will not get free actions ahead of you, you will not be subject to the Coup de Grace maneuver, and you will not be off-guard.
