Exorcist

This model has an invulnerable save of 6+

D3

While this model has 1-4 wounds remaining, each time this model makes an attack, subtract 1 from the Hit roll.

In your Shooting phase, after this model has shot, if one or more of those attacks made with an Indirect Fire weapon scored a hit against an enemy unit, that unit must take a Battle-shock test. Each time such an attack destroys an enemy model that has the Deadly Demise ability, the model's Deadly Demise ability inflicts mortal wounds on a D6 roll of 5+ instead of a 6.
