Though about the Elibis stone.
Is there allot of confusion about what it does?
According to GURPS it has a Paralasis spell. But I doubt that. I'm thinking that "It made Alric Balors equal" is meant literally in that the Elbis stone souped up Alrics power enough for Alric to Hit him with the Paralasis and keep him Paralysed for 30 seconds.
Now also it said somewhere that Alric was not the most powerful of the Nine ine battle of Magically but that his advantage is that he was more tactically minded. this also shows that he wasn't Mazzarin (But thats another argument.)
