Blesssed Mark of the Old Ones The character may reroll a total of D3 (roll at the start of the game) single D6's per game. Each reroll entitles the player to take a single D6 of his own that directly affects the character (including one of the dice rolled as part of a 2D6 etc) and roll it again.
This can potentially cause Irresistible Force or avoid a Miscast. Remember that you cannot reroll a reroll.
