The Grudgebreaker follows the rules for Random Movement and Random Attacks. In order to determine the Movement and Attacks value of the Grudgebreaker, roll an Artillery dice rather than a set of D6's (roll separately for Movement and Attacks). Whenever you attempt to move or attack with the Grudgebreaker you may re-roll the Artillery dice if it didn't score a Misfire. If a Misfire is rolled, roll a D6 and consult the Grudgebreaker Incident Table. If a Misfire results on the re-roll it automatically causes a Clunk result.
