Raveners

Each time a melee attack is made against this unit, subtract 1 from that attack's hit roll.

Each time a model in this unit makes a melee attack, if that model is not equipped with any ranged weapons, re-roll a hit roll of 1.

During deployment, you can set up this unit underground instead of setting it up on the battlefield. If you do so, then during the Reinforcements step of one of your Movement phases, you can set up this unit anywhere on the battlefield that is more than 9" away from any enemy models.
