Deathwing Knights

Once per battle, in any phase, this unit can summon a Watcher in the Dark. When it does, until the end of the phase, models in this unit have the Feel No Pain 4+ ability against mortal wounds.

Each time an attack is allocated to a model in this unit, subtract 1 from the Damage characteristic of that attack.

4+

If a Character unit from your army with the Leader ability can be attached to a Terminator Squad, it can be attached to this unit instead.

At the start of the battle, you can set up one Teleport Homer token for this unit anywhere on the battlefield that is not in your opponent’s deployment zone. If you do, once per battle, you can target this unit with the Rapid Ingress Stratagem for 0CP, but when resolving that Stratagem, you must set this unit up within 3" horizontally of that token and not within 9" horizontally of any enemy models. That token is then removed.
