Fleshripper

A model attacking with this weapon Piles-in and fights at Initiative step 1, unless it has the Dreadnought Unit Type or Monstrous sub-type.

If a model has the Shred special rule, or is attacking with a Melee weapon that has the Shred rule, it re-rolls failed To Wound rolls in close combat.

Similarly, if a model makes a Shooting Attack with a weapon that has the Shred rule, it re-rolls its failed To Wound rolls.
