Daydream

You target one creature that you know exists, within range. You reach into its mind attempting to force constant unconsciousness. The target immediately makes a wisdom saving throw or falls unconscious. At the start of each of the creature's turns, they may repeat this save to wake up. Also any time the creature takes damage while unconscious, they may repeat this save as well. At the end of each of the player's turns while the spell is active they must repeat this saving throw or fall unconscious again. Undead and creatures immune to being charmed cannot be affected by this spell.
