Cartographica Rogue Trader

If your army is Battle-forged, you can include one Agent of the Imperium unit in each Imperium (excluding Fallen units) Patrol, Boarding Patrol, Battalion, Brigade and Arks of Omen Detachment in your army without those units taking up Battlefield Role slots in those Detachments. The inclusion of an Agent of the Imperium unit does not prevent other units from their Detachment benefiting from Detachment abilities (e.g. Chapter Tactics), and it does not prevent other units from your army benefiting from abilities that require every model in your army to have that ability (e.g. Combat Doctrines). An Agent of the Imperium unit included in a Patrol, Boarding Patrol, Battalion, Brigade or Arks of Omen Detachment in this manner is ignored for any rules that state all units from that Detachment must have at least one Faction keyword in common (e.g. in a matched play game), and when determining your Army Faction.

An Agent of the Imperium unit can never be included in a Brood Brothers Detachment

In your Command phase, select one friendly Navis Imperialis Core unit within 9" of this unit's Cartographica Rogue Trader model. Until the start of your next Command phase, each time a model in that unit makes an attack, add 1 to that attack's hit roll.

This unit"s Cartographica Rogue Trader model has a 4+ invulnerable save. Other models in this unit have a 5+ invulnerable save.

If your army is Battle-forged, you can include a maximum of one Cartographica Rogue Trader model in each Detachment in your army. This model cannot be taken in a compulsory Battlefield Role slot.
