Apathy

Your actions lose vibrancy as your will to live is drained away.   Each point gives -1 to Charisma Checks and Saves, and your Proficiency Die is reduced by 1 step.   When your Proficiency Die becomes 1d0, any further Apathy becomes Hopelessness instead.  

Recovery

Whenever you complete a Night's Rest, reduce your Apathy by 1. Some magic can also remove Apathy.
