Narcolepsy

A rare disorder that causes one to randomly fall asleep.

• Once per rest (Short/Long), the DM can roll 1d20 at any time, if the number rolled is 4 or lower, you fall unconscious.
  • The player can also choose to roll instead if it could be funny or otherwise worthwhile.
• You can take a long rest in only 4 hours as opposed to 8. 
• You can sleep in your armor without penalty.
         But why ?...
• At 40% health (or less) you must make a Constitution Saving Throw (DC 5) after receiving the damage or fall Unconscious for 1 round.
         When Unconscious in this manner enemies act as if you had died.
