You can put opponents to sleep with your grip.
Prerequisites: Str 15, Combat Martial Arts, Improved Grapple
Benefit: If you have successfully initiated a grapple, you can declare that you are beginning a Sleeper Hold. On your next turn, you inflict 1d6 NL, and on the next turn after that, 2d6, until either your opponent breaks the grapple or falls unconscious. You can perform a Sleeper Hold only on creatures with discernible anatomy whose neck is small enough that you can get your arms around it.
