Either lure them to spots like varrock sewer, where once the guy climbs down, there'll be a huge death dot piling kills on the victim OR do a back-stabbing technique where they'll recruit victims into their clan at the grand exchange, then once in wilderness (make up some reason such as a war with opposing team) pile and bs the victims they have gathered at the GE.
If I had any time, I'll join, but seeing I'm pretty busy with things, I'll think about it.
Idea: wait out side of the house portal in rimmy, i think that is a multi area and a lot of people home tele for safty not know that a random can pull them from the house and leave them defencless cuz you can't enter your house while being attacked. me and my friend once stood outside that portal all day, he teleblocked and i barraged while he ranged. we made huge money off it that day till stupid one itemers just happen to walk by and try to take us so we stopped.
