Lohrtar, I am sure Belgadeth meant if he had malloran and pentacle up, that the jj::sj macro wouldn't work, and I assure, the knight will be hitting the malloran if he uses that macro.
As far as mists, like Fistandantilus said, it not only hinders the opponent, but the mage too. So I would suggest learning to fight, defend and heal in them. I would suggest pills. If you get into big trouble.
And anyone who pentacles against a knight is silly, unless it is another knight. which still isn't too smart, when you have fullparry.
