At the end of the opponent's Magic phase, the Slann Mage-Priest can store a single unused dispel dice remaining in your pool. At the beginning of your next Magic phase, roll a D6; on a 2+ you can add that dice to your power pool (this cannot take your power pool beyond the normal limit). On the roll of a 1, that bonus dice is lost. If the Slann is slain before his next Magic phase, the bonus dice is lost.
