I think this is the most recent version.
MIGHT OVER MAGIC [-2]
Description: You can shatter magical effects through physical force.
Skills Affected: Might, Fists, Weapons.
Effects:
Disruptive Strikes. You destroy ongoing spells by hitting them. Doing so requires you to roll your Might skill plus the weapon rating of your melee attacks (including Strength bonuses) against a difficulty equal to the spell's strength or complexity. If you succeed, the spell ends.
Parry Magic. You may use your Might skill plus half of any stress bonus you have from Strength Powers in place of your Athletics skill to defend against magical attacks and maneuvers.
Anti-Magic Attacks. You may use Fists in place of Might with this Power, but you receive no benefit from weapons while doing so unless you can wield them with Fists. You may also use Weapons in place of Might with this Power, but only if you are armed with a weapon suitable for use with Weapons.
Skill Over Magic [-0]. When you use your Might (or Fists, or Weapons) skill to defend against a magical attack with multiple targets, you may allow any number of other characters targeted by the same effect to use your defence roll in place of their own. However, you do not benefit from Strength or weapon ratings when using this Power.
Living Counterspell [-1]. When you use your Might (or Fists, or Weapons) skill to defend against a magical attack with multiple targets, you may allow any number of other characters targeted by the same effect to use your defence roll in place of their own.
Superior Might Over Magic [-2]. Add four to your Might (or Fists, or Weapons) skill when using it with this Power.
It used to be on the wiki, but IIRC the author asked for it to be removed.
