You cannot move when in line of sight of humans so you need to catch them off guard you cant do that easily tho as you make scraping sounds as you move, if you are spotted teleport away around a corner and try to get them, be ruthless as if you make a mistake you can just dip, if they make a mistake CRUNCH,


If they group up do the same thing wait for them to split up, if they stay grouped then i cant help you as there is no way they are leaving their friend :c
