actually, the Inquisitor was never a mage (:
if a monk is now a novice in robes, who prays and sweeps the floor with a broom in the temple, then in D&D, he is a nimble and strong warrior who possesses directed energy abilities to some extent; one could say he is somewhat of a warrior.
but an Inquisitor (not the Warhammer one^___^) has always been a psychopathic fanatic who hammers nails and heads with a hammer, pointing a trembling finger at the heretic and spitting on him. there is not a drop of magic in him

I was looking for our posts with Arko about Inquisitors, but I couldn't find them =(
