This spell sends creatures into a magical slumber.

Any creature of the Caster's choosing within both a range of 90 feet and that have the ability to hear the lullaby must succeed on two of the three following checks, in descending order; Dexterity, Constitution, and Wisdom. If two of the three are failed, the target will fall unconscious for the duration of either a short or long rest, according to the caster's preference, and the duration of the lullaby.

Creatures immune to being charmed are affected normally; creatures immune to being put to sleep by magic take advantage on all checks, but are still susceptible if two checks are failed. Undead are immune to the song. 

Due to the powerful nature of the spell, it may only be acquired through two means, as far as any mortal knows. A lifetime of training and dedication to master just this one spell, or it may be obtained from using the Wish spell, hence the name. Casting Wish is far easier to do, despite even the rarity of that spell alone. 

Legend has it that this spell could lull even the gods themselves to a peaceful rest.
