Chaplain Cassius is amongst the oldest members of the Ultramarines Chapter, discounting those who fight on with the blessings of internment within Dreadnought armour. Although close on four centuries old, his eye remains sharp and his aim steady, and his sturdy presence within the Ultramarines battle lines fills the hearts of his younger brethren with pride. Cassius can recall tales of the first Tyrannic war when he fought alongside Marneus Calgar, always "young Calgar" to Cassius, to purge Ultramar of the horrific denizens of Hivefleet Behemoth. His impassioned words have carried the Ultramarines forward into battle on a thousand worlds, firing them with his own deeply-held passion and belief.

An Ultramarines army of any size may include Chaplain Cassius. If you decide to include him then he counts as one of the HQ choices for the army and may act as the army's commander if desired. Cassius must be used exactly as described below, and may not be given additional equipment from the Space Marine Armoury. Cassius can be used regardless of whether the players have agreed on the use of special characters (don't worry, the rules are balanced!).

Wargear: Boltpistol, frag grenades, crozius arcanum (counts as power weapon), rosarius (4+ invulnerable saving throw), Terminator honours (bonus attack included below), bionics.

Tyranid Hunter: Cassius is one of the few surviving veterans of the first Tyrannic war. He has fought in many battles against the Tyranids and understands them all too well. His hard won experience has led the Ultramarines to victory against these aliens, overcoming both their heinous weaponry and inhuman constitution. Cassius and any Ultramarines squad led by him may re-roll its dice to wound against Tyranids for any shots taken using rapid fire and/or pistol weapons. If the second roll still fails to wound, the dice may not be re-rolled again.

Great Knowledge: Any Ultramarines unit within 6" of Cassius may re-roll its Morale checks, accepting the second result as final. Note that this ability can be used even if a Morale check is passed on the first roll, so you can use it to try to make sure that the Ultramarines fall back in disadvantageous or outright dangerous situations (Cassius counsels with both strength and wisdom).

Independent Character: Unless accompanied by a bodyguard, Cassius is an independent character and follows all the special rules as detailed in the Warhammer 40,000 rulebook.

Bodyguard: Cassius may be accompanied by a bodyguard as detailed for a Chaplain in the Codex Space Marines army list.
