===Battle Traits===
'''Deathless Minions:''' Each time you allocate a wound or mortal wound to a friendly '''DEATH''' model within 6" of your general or a friendly '''DEATH HERO''', roll a dice. On a 6+ the wound is negated.

This is your only battle trait, and note that it is on a model by model basis - if half your unit is within 6" of a hero and the other half isn't, only the models within 6" of a hero get the death save.
