Exhausting Nanites
Source
Interstellar Species pg. 27
Your nanites utilize electrical pulses to cause exhausting muscle spasms and electrical interference. Weapons you form with your gear array gain the fatigue critical hit effect (Starfinder Armory 31). Once per day, after you damage a creature with a weapon formed from your gear array, you can use a nanite surge as a reaction to impose the effects of slow on the target (Fortitude negates) for a number of rounds equal to half your Constitution bonus. Creatures immune to electricity are immune to exhausting nanites.
