8th Ed. Great Bow Stegadon Question

[AirshipEngineer]

The GreatBow in the Rules Is a Bolt Thrower so it penetrates Ranks and Has poisoned attacks so if i roll a 6 do i automatically pass all the ranks Toughness tests or just the first Toughness test. thanks.

it is a good question. so good that it is in the FAQ

Q. The Stegadon’s giant bow is Poisoned. Does this mean that a
roll of 6 to hit will penetrate all ranks automatically? (p55)
A. No – only the first hit wounds automatically. If that model
is slain then roll to wound the next as normal.

EDIT: oh, and lets be careful with the terminology here in the rules forum. there is no "toughness test" involved here. a toughness test is something else. Also, remember that the bow will only penetrate a rank if the model dies. even if you can not use armour against a giant bow, you CAN use a ward or regeneration save. Just because you manage to score a 6 does not guarantee a dead model (though in most cases it does )
