Patrol

The term patrol refers an NPC or mob of NPCs, usually hostile, which moves along a set path rather than wandering around within a small radius or standing still.

Learning to aggro and separate a patrol from other mobs is a key tactic in making encounters with numerous hostiles easier and vital in surviving difficult areas of the game.

The affiliation of patrols may differ from one patrol to another on the same map, so sometimes patrols will fight each other without player intervention.
