Living Icon of the Chapter Friendly Howling Griffons units from either Codex: Space Marines or the Space Marine Siege Assault Vanguard army list, and at least one model within 12" of Chaplain Dreadnought Titus gain the Fearless special rule.
Venerable If a Venerable Dreadnought suffers a penetrating hit, you can make your opponent re-roll the result on the Vehicle Damage table. You must accept the second result, even if it is worse than the first.
Chapter Tactics When choosing an army, all models in the same Detachment or Formation must be drawn from the same Chapter. If a unit's datasheet contains a Chapter in brackets after the Chapter Tactics special rule - for example, "Chapter Tactics (Ultramarines)" - the unit must always be drawn from this Chapter, and therefore cannot be included in a Detachment or Formation with any units that are drawn from other Chapters. All models drawn from a given Chapter benefit from that Chapter's Special Rule. If a unit contains models drawn from two different Chapters, it counts as from neither Chapter, and thus benefits from neither Chapter Tactic.
