Droning of the Cicada

Summoning the annoying might of the common Cicada, this spell creates an emanation ten miles in diameter centered on the caster. For the duration of the spell, all creatures within the spell's effect can not sleep, meditate, or otherwise gain the benefits of long rest as the amplified sound of thousands of cicadas invades their very minds. Creatures that do not need rest, or that do not hear are immune to the effects of this spell. 

A successful Wisdom save at the start of the effect of the spell prevents the creature that saved from being affected by the spell. Dispel Magic cast with at least a 7th level spell slot, Greater Restoration, Limited Wish, Wish, or making the creature deaf will remove the spell's effect from that creature, even if it regains its hearing later.

A creature that enters, or leaves and then re-enters the area of effect must make the save or be affected by the spell.

The caster of Droning of the Cicada is immune to the effects of their own spell. While concentrating on the spell, the Caster may not move more than 100 ft from the original point of origin of the spell. They can rest normally, and are considered to be concentrating on the spell even while sleeping.
