You can farm tons of souls in that area by ringing that bell and not killing the mummies.brehs...Undead Crypt is the greatest place to invade. i get so much hatemail
basically just invade and go hit the bells in the area. this spawns a fukk ton of enemies that the host will have to deal with.
most of the time they die before i even have to fight them. i love to send people messages after just saying "ding dong motherfukker". i get some hilarious messages back.
