Power Word Slumber

7th-level enchantment

Casting Time: 1 action

Range: 60 ft.

Components: V

Duration: Instantaneous

You speak a word of power that causes a wave of drowsiness to wash over one creature you can see within range. If the target has 100 hit points or fewer, it immediately falls asleep and is unconscious. Otherwise, the spell has no effect on it. The creature remains unconscious until it takes damage.

A target is also unaffected if it is immune to being charmed.
