This card can be played when it is your turn to cast a spell. One of your wizards engages an enemy wizard of your choice in a battle of wills. Both players immediately roll a D6 and add the magic levels of their respective wizards to their roll. The player with the highest total wins the duel and drives the knowledge of a spell out of the mind of the loser. The winner can immediately choose a spell card at random from the hand of the losing wizard and discard it for the remainder of the battle. If the two scores are equal the duel is a draw and has no effect on either wizard. If this card is not used in the magic phase it is placed on the discard pile at the end of the phase just like any other magic cards.
