The Statistics here are taken from FCS. Skills will be multiplied by the racial multiplier. Players should also be aware that non-player characters also level up while fighting.
If Screamer the False and Ponk are both killed or imprisoned, Thrall Masters patrols will cease to spawn in Venge, Grey Desert and The Eye.
Trivia
"The False" seems to be referring to this Screamer MkI being The False version of "General Screamer (The True)" a unique character of the MKII Screamer variety listed in the FCS but not actually spawned in the game. Similarly General Screamer (The True) would've spawned with the exact same armour but at Masterwork Quality, a Meitou grade Naginata Katana another polearm weapon, but with combat stats of 80.
Screamer the False is the only Screamer MKI with a bounty, as well as having the lowest stats of any other Screamer in Kenshi. (On Average)
Although Screamer and Ponk lack First Aid Kits in their inventory, if you put yourself in a cage on the top floor of their tower they will bandage your injuries.
