This guard has a much longer patrol route than usual; while regular guard patrols are 8 AP apart, the Harbinger's patrol points are 25 AP apart. It will usually take this guard multiple turns to complete it. This makes early exploration in OMNI more dangerous than usual, since a room that has been free of guards one enemy turn may not be the next.
