Pyrofane Great Cannon

Each time this unit uses a Shoot ability, if it is in a fortified position, pick either the Cannonball or Grapeshot weapon characteristics for all the attacks it makes with its Great Cannon. If it is not in a fortified position, use the Grapeshot weapon characteristics.

This unit establishes a fortified position and remains in a fortified position until it either uses a Move ability or is removed from the battlefield. While this unit is in a fortified position, subtract 1 from the Rend characteristic of weapons used for attacks that target this unit.
