Chapter Relic (IH): Betrayer's Bane

Weapons with the Master-crafted special rule allow the bearer to re-roll one failed roll To Hit per turn with that weapon.

Ranged weapons with this special rule roll an additional D6 when rolling to penetrate a vehicle's armour at half range or less. If the weapon is more than half its maximum range away, it rolls to penetrate as normal.

If a weapon has both the Melta and Blast special rules, measure the distance to the centre of the blast marker after it has scattered. If this is half the weapon's range or less, all hits caused by the blast marker roll an addition D6 when rolling to penetrate a vehicle's armour. If the centre of the blast marker is more than half the weapon's maximum range away after scatter, roll to penetrate as normal.
