Comatose

Instead of sleeping, you go into a state exactly as if you were under the effects of the feign death spell. You are somewhat capable of determining your surroundings, but not to your normal level. Whilst in this “coma,” you have disadvantage on Perception checks, and cannot open your eyes unless you choose to wake up. You can go under these effects for 1 hour at a time, which will give the benefits of a long rest. However, during the next 24 hours, you must return to this sleep every 7 hours, or take 1d20 necrotic damage per hour past. For all spells and effects, you are considered an undead.
