Reducing the M reduction to 1 constantly would make the skill pointless.

I vote to leave this as-is. "Perma-knockdown" is only successful if the mage stays in a one-tile range, which most would rather not do, I'm sure.

If you ever get tome smacked in melee range, unless your move is greater than the person smacking you with the tome, you will never be able to get away. If you use your one action at 5m to run away, they use their two to run up to you, and tome smack again. For a trait that is meant to give diversity to different weapons, this one is way too crippling in particular situations.
