Go To Sleep, Go To Sleep, Go To Sleep

You’ve developed a technique that allows you to efficiently pacify enemies without the need to cause harm to them.

• While grappling a target in this way, the target is unable to speak.
• If you maintain a grapple for a consecutive number of rounds equal to the target's constitution modifier (minimum of 2), the target must make a constitution saving throw each turn thereafter until the grapple ends. On a failed save, the creature falls unconscious, ending the grapple. The save DC equals 10 + your Strength modifier, increasing by 1 for each successful constitution save against the grapple.
