Daemon Armour (Chaos Space Marines)
Daemon Armour are suits of corrupted Power Armour worn by the most powerful Chaos Space Marines Champions, that are imbued with various bound Daemons by Chaos Sorcerers. These fiendish creatures lend portions of their strength, resilience and fearsome powers in return for the souls of those slain with their aid.[1]
