Here's my final catch all for the Badab War Characters that use the Ultramarines Chapter Tactics, or have unknown Chapter Tactics in the case of the Exorcists.
Howling Griffons: Chaplain Dreadnought Titus
Titus has the standard profile and rules for a Venerable Dreadnought, with a few extra rules to convey his role as a Chaplain Dreadnought of the Howling Griffons. He has a dreadnought close-combat weapon with heavy flamer or storm bolter, as well as a lascannon (which for some reason isn’t twin-linked like it is for every other Dreadnought) or assault cannon. He also comes with extra armor.
To mimic the Chaplain rules, Titus has Hatred and makes ever friendly Space Marine unit within 12” Fearless. Finally, and perhaps most useful, Titus is scoring if he is your warlord. Very unusually, Titus does benefit from Ultramarines Chapter Tactics even though he’s a vehicle. That’s not a huge change, but it could prove extremely useful throughout the course of the game, particularly benefiting him if he needs to get into assault with a juicy target.
Titus isn’t the most competitive choice, but he is unique as a scoring Dreadnought HQ. He’ll be most useful anchoring a firebase, as he’ll provide some firepower, make the surrounding units Fearless, and act as a counter-charge unit.
