Curse of the Phantom Mosquito

During sleep in a long or short rest, the character will suffer from 1d4 incidents of waking convinced that a mosquito was buzzing in their ear. It will take time to get back to sleep and add 1 level of exhaustion unless a CON14 save is made. Exhaustion points from the previous night will be reduced by 1 if the save is made. See special rule if exhaustion level 5 is reached.

The spell can be cast by touching the victim or it can be bound to an object to be released when touched.  The curse will not be triggered if a cursed object is touched by the caster. Once the spell is triggered, the item is no longer cursed.

The spell potency can be increased by using higher level spell slots.
