Fatality is a guaranteed kill, with no chance of survival, like beheading. Brothers receiving it always die and can't survive with a [[Permanent Injuries|Permanent Injury]]. Destroying the head or cutting it off prevents a corpse from rising from the dead as a [[Wiederganger]].

[[The Surgeon (Follower)|Surgeon]] prevents brothers with no permanent injuries from suffering a fatality, except when they are devoured.

[[Bloodthirsty]] trait makes fatalities guaranteed if their chance is above zero.
