A Sergeant is an enemy type found in Atum.
Sergeants are hostile mobs and will attempt to melee the player if they see them. They spawn with a patrol made of a myriad of bandits types and will patrol the area.
Slaying one will cause the player to gain the Marked for Death debuff.
Sergeants spawn during the day in Strange Sands, Deadwood Forests, and Limestone Peaks biomes at random and are accompanied by a patrol of other bandits.
