Dream Breath (Summon Spell)

As you hold your hands with thumbs touching and fingers spread, a glittery mist come out in a 90-foot cone. Each creature in that area must succeed on a DC 18 Constitution saving throw or fall unconscious for 10 minutes. This effect ends for a creature if the creature takes damage or someone uses an action to wake it.

This spell can only be cast every 7 days unless otherwise said by the DM.
