-The '''Concussion Blow''' [[Special Move|special move]] was added during the [[Age of Shadows]] expansion. It adds between 10 and 30 extra [[Hit Points|hit points]] of damage. The amount of the extra damage is based on the difference between an opponent's [[mana]] and hit points; the greater the spread, the greater the damage. According to a [[Five on Friday - January 18, 2008|FoF]], formula for the damage bonus is the absolute value of the victim's current mana percentage minus his or her current hit point percentage, divided by four, plus ten.
