Threshold buffer, mk 3
Starfinder Armory p.89
This system monitors your vitals, injecting a burst of synthetic
adrenaline into your bloodstream when your body is on the
brink of death. You gain a number of additional Resolve Points
(depending on the model of your threshold buffer) that you can
use or lose only when you are dying or stable, such as to avoid
death, to stabilize, or to stay in the fight (Core Rulebook 250).
These additional Resolve Points don't count for the purpose of
calculating how many Resolve Points you must spend to stabilize,
and any unspent additional Resolve Points are lost the next time
you take an 8-hour rest to regain your normal Resolve Points.
