By imploring Mork for help, a Shaman gives the Greenskin player a chance of re-rolling dice during the remainder of his own turn.
If successfully cast, roll a D3 to determine the number of re-rolls the player can make. Each re-roll entitles the player to take any single D6 (including one of the dice rolled on a 2D6, 3D6, etc) he has rolled and roll it again. Any dice can be re-rolled, but as usual the player cannot re-roll a re-rolled dice. Any re-rolls not used by the end of the turn are wasted.
