Saving Throw: Foresight
A character who is Asleep can take no actions, save to attempt to save off the condition. (Normally, this is only done if there is noise that might awaken a sleeping character.) The character is automatically Prone, and will have nothing in their hands (if they were put to sleep mid-combat, such as by the Sleep spell, they will drop what they have in their hands).
When this condition is lost, the subject will instead become Dazed (save ends).
