Daemonic Stature
The Chaos Space Marine has mutated horribly, swelling to monstrous size and taking on the aspect of a mighty Daemon Prince. The model gains +1 Strength and +1 Toughness and counts as a monstrous creature. A monstrous model ignores armour saves and rolls 2D6+ Strength for vehicle armour penetration in close combat.
The model may not ride a Steed or be transported in a vehicle. They may only wield Daemon Weapons, Axes of Khorne, Plague Swords, combi-bolters, close combat weapons or great weapons and then only if they have the appropriate Mark. Because of its huge size a model with Daemonic Stature can be shot at even if it is with a friendly unit or within 6" of one, unless it is in close combat.
The bestial power of a Chaos Lord with Daemonic Stature is best applied in close combat. Consequently his Weapon Skill is increased to 6 and his Ballistic Skill reduced to 3.
A model with Daemonic Stature is at least 10' tall, and should always be based on a 40mm diameter base.
