When using the Sanity Table, a trainer who loses all their Will Points blacks out and enters a coma. They will not recover without extensive medical care. A player who is at half Will suffers a Breakdown. In combat, a breakdown will manifest as either Fight or Flight, for better or worse. Out of combat, roleplay the breakdown. These are serious breaks and at best can be bottled up, not resolved in a session.
