A Contemptor Dreadnought with this upgrade gains the Character Sub-type, the Master of the Legion and Eternal Warrior special rules and an iron halo (increasing its Invulnerable Save to 4+, but not replacing all the effects of the atomantic deflector), but may not select a Command Squad or any other unit using a variant of the Retinue special rule. In addition, it must be selected as the Warlord of an army that includes it.
