Twin-Linked If a shooting weapon has the twin-linked special rule, or is described in a model's wargear entry as twin-linked, it re-rolls all failed To Hit rolls.
For a Blast weapon, if the scatter dice does not roll a hit, you can choose to re-roll the dice with a Twin-linked Blast weapon. If you choose to do so, you must re-roll both the 2D6 and the scatter dice.
Twin-linked Template weapons are fired just like a single weapon, but must re-roll failed To Wound rolls and armour penetration rolls.
Hammer of Wrath If a model with this special rule ends its charge move in base or hull contact with an enemy model, it makes one additional Attack that hits automatically and is resolved at the model's unmodified Strength with AP-. This Attack does not benefit from any of the model's special rules (such as Furious Charge, Rending etc.). This Attack is resolved during the Fight sub-phase at the Initiative 10 step, but does not grant the model an additional Pile In move.
If a model with this special rule charges a building or vehicle, the hit is resolved against the Armour Value of the facing the charging model is touching. If a model with this special rule charges a building or vehicle that is a Transport or a Chariot, the hit is resolved against the building or vehicle, not the occupants or the rider.
