This lure is done by one player to another, when they are both killing Chaos Druids, for they herb drops, for example. Player one tells player two that he/she will find more and better chaos druids that drop more herbs if the player goes north through the metal gate. In fact, the player will only find level-193 Black Demon that will kill the player, besides other higher level monsters, such as some revenants. This way the scammer will have less competition for chaos druids and will have the victim's stuff. You are no longer able to obtain the victim's stuff now thanks to the grave stone update.
