Sleeper Strike
Source
Starfinder Enhanced pg. 85
You can energize your entropic strike to knock out an opponent in a single blow. As a reaction after successfully striking an opponent with your entropic strike, you can spend 1 Resolve Point to attempt to knock your target unconscious. The target must succeed at a Fortitude save or become exhausted for 1 minute; if they fail the save by 5 or more, they fall unconscious for 1 minute. Whether or not the creature succeeds at this save, it’s immune to your sleeper strike for 24 hours.
You must have the staggering surge or stunning strike discipline to learn this discipline.
