Avatar of Khaine

Melta weapons, plasma weapons, flame weapons and equivalent grenade and missile types cannot harm the Avatar in any way.
Not affected by gas weapons, poisons, virus, or blinding attacks (such as photon). 

Cannot be affected by psychology in any form and will automatically pass any Leadership-based test he is called upon to take. Can never be Broken and never needs to take a Break Test. Does not count as a "living" model.
