Sleep

Source sleep

The spell affects up to 8 Hit Dice of creatures, and you can choose the order in which creatures are affected by the spell. Any effect that would automatically awaken a sleeping creature instead allows it to attempt a new Will saving throw to awaken.

Augmented (8th): If you expend three uses of mythic power, you can target all living creatures other than you that have 8 Hit Dice or fewer in a 1-mile radius centered on you. Creatures that fail their saving throws fall asleep for a number of days equal to your tier. You can select a number of creatures up to your tier to not be affected by the spell.
