Haven't checked in a while, but by memory it's part of the "Attriubutes" and "AttributesEx" groups. If you look in your "Spell.h" and search for "Attributes", you'll get yourself your own reference list. However editing them is another story (correct me if i'm wrong, but I think it's hexidecimal), I don't know, much on editing them, yet to dable in it fully.
