Biomonitor

While it is functioning, a biomonitor provides detailed medical data and helps regulate your body’s systems. Creatures making Medicine checks on you while accessing the biomonitor do so with advantage, and you regain an extra hit point for every hit die you spend during a short rest.

Hacking. If the monitor is disabled via hacking or the character is subject to an EMP blast, the monitor goes into a failsafe mode. During this time, you suffer the effects of two levels of fatigue that cannot be removed until the implant is reset. Resetting the biomonitor requires a short rest and a cybernetics kit. Additionally, when a hacker who gains access to the biomonitor’s output data makes a successful attack roll against you they deal extra damage equal to their proficiency bonus. Resetting the implant removes this damage bonus.
