friend and i came across a bug that allowed us to take control permanently of all the dungeons spirits around the time that the first change for signet of binding was made, plowed through ALL of the bosses in duncan.
take a look(yes i >WAS< in kiss) im out now(thankfully)
over 20 spirits that would die and come back and could be summoned across the entire map plus the other 5 i made with my sin.
