With a single salvo of spinning axes, a Goblin-hewer can cut through several ranks of troops. When shooting a Goblin-hewer, roll an Artillery dice before making any rolls To Hit. The number of shots fired is equal to the roll of the Artillery dice plus a D3 modifier:
Per rank (including the rear rank, even if it is incomplete), if the Goblin-hewer lies in the unit's front or rear arc.
Per file, if the Goblin-hewer lies in the unit's flank arc.
However, if a misfire is rolled on the Artillery dice, no shots are fired and a critical fault has occurred. Roll immediately on the appropriate Misfire table to determine exactly what.
