Pain Shock Threshold
Pain Shock Threshold is a stat: The pain level at which this creature is downed from pain. Its minimum allowed value is 1% (effectively limited to 30%). Its maximum allowed value is 99% (effectively limited to 95%). Its default value is 80%.
When a pawn's pain level meets or exceeds their Pain Shock Threshold they will become incapacitated. Therefore higher values are generally preferable, however lower values also have there merit since they prevent pawns from continuing fighting until they are close to dying.
Mechanoids feel no pain and are therefore not affected by this stat.
