This lists all the npc's in the eye. Good for learning the trash pulls. After you get your ass handed to you, look at the names of the mobs that just pwned your face, look up their listing on the site, go to "comments", and usually ppl will have listed their abilities.
EDIT: Of course there is the option of looking up the mob's abilities BEFORE you pull, reducing the chance of getting pwned, just throwing that out there (hinthint).
