When Chaos first came the Runepriests were able to call upon these warriors, through their rituals, prayers and sometimes sacrificial offerings, to help them in their struggles and their presence is considered to be the proof that the Chaos forces will be the great opponents in Ragnarok and that the woeful day is ever coming nearer.

DETERMINED
The Einherjar are determined as described on the first page of the Norse battle bestiary, see the Norse battle bestiary for details.

REGENERATION
The power of Odin infuses the Einherjars's bodies with vitality enabeling the Einherjar to regenerate any wounds they might recieve, but the flow of power is not constant and will not always work immediatly.
If an Einherjar model is wounded roll a D6. If the roll is 3+ then any damage inflicted by the wound is immediatly regenerated with no further effect. But if the roll is 1 or 2 then the Einherjar is wounded as normal and will be removed as casualty if reduced to 0 wounds.
Magical armour somehow interfears with the connection that Einherjar have to Odin and if Einherjar Characters wear it they will not instantly regenerate as other Einherjar but so slowly that it will not have any affect until after the battle.

PSYCHOLOGY
The Einherjar have all died many various deaths and nothing can really shake their nerve anymore.
Einherjar are immune to all fear and terror caused by their foes and will automatically pass amy panic test they will be called upon to take.
