"Jailers are former inhabitants of the Profaned Capital who managed to escape its collapse and were recruited by Pontiff Sulyvahn to oversee the prison. They are tall humanoid enemies that carry lanterns and wield branding irons in combat. Their lanterns emit a gas that is most likely only to signify an aggro toward the player. It does no damage, nor inflicts any sort of effect buildup.

By far their most dangerous ability is to rapidly reduce the player's maximum health just by looking in their direction. Their weapons also slow your movement and negate the use of Estus. Both attacks combined make for a devastating combination that can kill a player with full health in just a few seconds."
