On a failed save, you send it into a magical slumber, causing it to fall unconscious for the duration.
This spell ends for a creature if it takes damage or someone uses an action to shake or slap it awake. Additionally, a creature can repeat the saving throw each minute or if it hears an extraordinarily loud noise such as the thunderwave spell, ending the effect on itself on a success.
You can target one additional creature for each additional mana expended. The creatures must be within 5 meters of each other when you target them.
