Characters that are part of a Detachment or Formation presented in this book must always issue and accept a challenge whenever possible. If you have several models in a combat with a special rule to this effect, you can choose which model issues or accepts the challenge.
A unit that contains at least one model with this special rule receives a +1 bonus to Deny the Witch tests.
As long as a Dreadnought from this Formation remains within 6" of Bjorn the Fell-Handed, it has a 5+ invulnerable save.
Whilst Bjorn the Fell-Handed is alive, all units in this Formation re-roll all failed To Hit rolls in close combat.
