Curse of Abyssal Inconvenience

This ritual spell allows you to call forth the wrath of the Abyss to torment your foes. Upon completing the ritual, an Abyssal Chicken is instantly summoned within 100 feet of the target of this spell. This creature is not under your control and follows no orders other than spending the next seven days finding any way possible to inconvenience the target. This includes, but is not limited to, eating every single one of the target's shoes, destroying any fragile objects owned by the target, hiding above doorways and launching itself onto the target's head, or even simply screeching its unholy cry at random hours of the night. The Abyssal Chicken summoned in this way has the following special features:

Terrible Neighbor: The Abyssal Chicken can not physically harm the target, however, psychic torment is the creature's primary goal. If the target is able to see and hear the Chicken while attempting to long rest, there is a 50% chance (1d100 rolled by the DM) that the target can not complete it, suffering a point of exhaustion and receiving none of its benefits.

Unstoppable: If the Abyssal Chicken is destroyed, two more are instantly summoned within 100 feet of the target, with the same target and goals. This effect stacks. For each Chicken present beyond one, there is a 5% increase in the DC for the target to avoid exhaustion.

The Chicken (or Chickens) are banished back to the Abyss and the spell ends after seven days, with a successful casting of Remove Curse, or Dispel Magic (DC 15), or if the target dies.

Rule of 7: After casting this spell, you cannot cast it for another seven days. 

At Higher Levels: If you cast this spell at 7th level or higher, the Abyssal Chicken, and any summoned for the duration of the curse, is infused with chaotic power. It is now able to damage the target, and will not rest until the target is dead.
