Scry was like conjurers clairvoidance. Shows you the room of the person you're scrying and all the people in the room.
Tesseract was one of their powers, like the conjurer's spell but without a down timer. Group gate basically.
Scourge was a sick offensive spell/power that dis maledictions as well as damage.
Transform, which was what scion's despoil came from. It gave you a temporary +hp, I can't remember but I want to say it was something like 60-70% of your max hp.
Brew was sort of my favorite(even though I never got to play one in CF, other MUDs I did though) You brew any item and it makes a magical pill/potion/wand/scroll/stave(talisman).
And there was one power that I forget what it was called, but you could transfer some of your mana(like 30mana at a time) to anyone else in the cabal no matter where they were.
I think they got a charmie, I think, unsure what it was though... I might be wrong on this one.

If there was more I'm blanking on it, my memory is kinda hazy.
