Peritarch Targeter

A unit that contains at least one model with this special rule ignores the effects of Night Fighting (see page 308) and no model may make Shrouded rolls to negate Wounds inflicted by their attacks.

When attacking with a weapon that has this special rule, the controlling player may re-roll all failed To Hit rolls.

Twin-linked Blast Weapons
If the Scatter dice does not roll a Hit, you can choose to re-roll the dice when making a Shooting Attack 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
Twin-linked Template weapons are fired just like a single weapon, but must re-roll failed To Wound rolls and Armour Penetration rolls.
