By outfitting your armor with magnetized, short-range grapplers that are linked to its environmental sensors, this upgrade serves as an extra protection against explosive decompression. If you fail a Reflex saving throw against forced movement in space (for instance, being pulled through a hole punched in a starship’s hull or a malfunctioning airlock), this armor upgrade engages immediately after you are moved 10 feet, grappling a nearby solid surface with a length of titanium alloy cable line and stopping your movement. Unfortunately, the vacuum rappeler doesn’t prevent falls or forced movement in areas with an atmosphere. The upgrade holds a total of 40 feet of line, which can be retracted into the upgrade with 10 minutes of work.
