i was just wondering if there were specific tactics for doing this? the damn ghosts get

can anyone help me? @ A Simple Farmer if you ever look at this i have watched your video lol and when i tried it myself it seemed like there were waaaaay more spirits that popped than in your youtube video.

So i was wondering if anyone at all could help me whether its advice on guru or even showing me in game, whichever is possible anything helps.

thanks
