Anyway, the ghosts gain stacks when they take damage, dots that tick quickly and do little damage are the best way to get stacks quickly. How many stacks you can get will depend on your comp. I wasn't tanking, so I just gripped the ghost I wanted out of the pack, dotted it up and waited with control undead until it was pretty low. I also had an affliction lock dotting it.
