A bolt thrower is a powerful weapon that can hurl its bolt through several ranks of troops, piercing each warrior in turn. If it hits, resolve damage against the target using the bolt thrower's full Strength of 6. If the first model hit is slain, the bolt hits the trooper directly behind in the next rank: resolve damage on the second model using a Strength of 5. If the second trooper is slain, the model directly behind in the next rank is hit: resolve damage using a Strength of 4. Continue to work out damage as the bolt pierces and slays a model in each rank, deducting 1 from the Strength for each rank pierced.
Stop rolling once the bolt fails to slay a model or it has gone through all of the ranks in the unit.
Armour saves are not allowed against hits from a bolt thrower because the missiles are so fast and deadly that any armour is pierced along with its wearer. Ward saves may be taken as normal. An unsaved wound causes not 1 but D3 wounds, which means that even large monsters can be slain by a hit from a bolt thrower.
