Chaplain Cassius

A Rosarius confers a 4+ invulnerable save.

Models equipped with assault grenades don’t suffer the penalty to their Initiative for assaulting enemies through cover, but fight as normal.

When assaulting a vehicle, each model using Krak grenades can only ever make one attack, regardless of the number of Attacks on their profile and any bonus attacks. Against vehicles, Krak grenades have an armor penetration value of 6+D6.

The Chaplain and all members of the squad he's joined are fearless

On a player turn in which he assaults, a Chaplain and all members of his squad can re-roll failed rolls to hit.

If a model with this ability suffers an unsaved wound, roll a dice. On a 1, 2 or 3, take the wound as normal (removing the model if it loses its final Wound). On a 4, 5 or 6, the injury is ignored and the model continues fighting. This ability cannot be used against wounds from weapons that inflict instant death (by having a high enough Strength or a special rule to that effect; even if the model is an eternal warrior). Neither can it be used against wounds from AP1 and AP2 weapons, power weapons and any other wound against which no armour save can ever be taken (like wounds from power fists, Dreadnought close combat weapons, rending weapons that roll a 6, Perils of the Warp, failed dangerous terrain tests, etc).
