The giff bireme resembles a single decked groundling bireme, and indeed such craft were initially used as the frames for early versions of this vessel. Its rowing banks are planked over and its prow removed, replaced with a great bombard of cold iron banded with steel rings, which runs half the length of the ship and can only fire in the direction the ship is moving. In game terms, this means that the great bombard will fire only fire along a straight row of hexes, which the ship is facing.
    The great bombard is of masterwork quality (all 1½ tonnage in size), which gives a +1 to hit bonus to hit. This mighty bombard may also be capped with a great brass blunt ram, usually sculpted in the shape of a giff's head.
    When in combat any attack that exceeds a to hit roll by 3 or more has a 1 in 10 chance to damage the great bombard it self. The great bombard can take 50 hit points of damage before it becomes inoperable.
