Iron Halo

The Iron Halo is a special reward given to Space Marines who show exceptional initiative or bravery in battle. In game terms it has the same effect as a rosarius, giving the model a 4+ invulnerable save that may be used instead of the model's normal armour save. No more than one model per army may have an Iron Halo and any model wearing Terminator armour or who has a rosarius may not be given this piece of wargear.
