Fall of Cadia book in hand, ask away!
Celestine, Inquistor Greyfax and Belisarius Cawl can be included as an HQ choice for any Army of the Imperium Combined Arms or Allied Detachments (specifically), regardless of faction! In addition, Belisarius Cawl can replace any Tech-Priest Dominus in any existing Cult Mechanicus Formation, and Inquisitor Greyfax can replace an Inquisitor in any Inquisitorial Formation.
Formations look pretty average to me - they need far too many units to be used in any 'normal' sized game. Could be fun for larger games though.
Triumvirate of the Imperium (Formation)
- Belisarius Cawl, Celestine, Inquisitor Greyfax.
- Friendly Army of the Imperium units within 12" of two or more Triumvirate models get Stubborn and auto-pass Pinning tests. If they are within 12" of all 3 models they get Fearless instead (Geminae don't count as models for this rule.
- If one of the Triumvirate is the Warlord, then all 3 of the models get to use their Warlord Trait.
Conclave Acquisitorius (Formation)
- Belisarius Cawl, 1-2 Battle Maniples or 1 War Cohort, 1 Holy Requistioner, 0-1 Cohort Cybernetica, 0-1 Numinous Conclave, 1-2 Imperial Knights or 1 Baronial Court
- Everything gets Canticles of the Omnissiah
- Each Character may upgrade one of their weapons (except relics) to have Master-Crafted
- If the formation has the maximum number of units, everything gets Doctrina Imperitives
Wrathful Crusade (Formation)
- Celestine, Inquisitor Greyfax, 1 Space Marine Captain, 0-1 Sternguard, 2-4 Crusader Squads, 1-2 Assault Squads, 1 Militarum Tempestus Platoon. All Space Marine must have Black Templar Chapter Tactics
- Everything gets Crusader
- If the formation has the max number of units, everyone gets Zealot
- All units can re-roll failed Charge rolls. If you roll 10 or more for your charge range, you get Furious Charge.
Grand Convocation Detachment:
- Units can be drawn from Codex Astra Militarum, Cult Mechanicus, Imperial Agents, Imperial Knights or Skitarii. The available units are restricted to mainly the ones from Codex: Skitarii, Cult Mechanicus and Imperial Knights though. Enginseers are the only Guard unit you can take. You also must also include units from at least two different factions.
- HQ: 2-4, Troops: 4+, Elites: 0-6, Fast Attack: 0-6, Heavy Support: 0-6, LoW: 0-3
- All Vehicles get It Will Not Die. If they are within 12" of any HQ from the detachment, they also get Power of the Machine Spirit
- If the formation hast the max number of units (except troops, since you can take unlimited lol...) then everything gets Canticles of the Omnissiah
- Warlord can re-roll Warlord Trait
Castellans of the Imperium Detachment
- Units can be drawn from basically any Army of Imperium codex and their supplements. There's literally big lists of units you can take for each slot, which at a quick glance seems to basically include everything besides unique characters (aside from Black Templar, Adepta Sororitas and Inquisition unique characters though, which can be taken. Pask and Yarrick too). Interestingly enough, Codex: Inquisition and Codex: Adepta Sororitas are listed alongside Codex: Imperial Agents as available sources. That should clear that debate right up. You also must also include units from at least two different factions. Edit: Blood Angel, Dark Angel, Space Wolves, Grey Knights, Death Watch, Cult Mechanics, Skitarii, Sisters of Silence, Adeptus Custodes and Legion of the Damned are not available in the Castellans of the Imperium Detachment. I'm pretty most everything else, including Assassins and Cataphractii/Contempors, are though. Lord of War options are Imperial Knights (specifically the ones from Codex: Imperial Knights) and Baneblade variants.
- HQ: 2-4, Troops: 4+, Elites: 0-6, Fast Attack: 0-6, Heavy Support: 0-6, LoW: 0-3
- All units get Hatred. If you have the max number of units, except troops, everyone gets Zealot
- Each time a Troops Choice is destroyed, roll a d6. On a 5+ an identical unit immediately goes into Ongoing Reserve, and counts as a unit from this detachment (so it can potentially be recycled again later)
- Warlord can re-roll Warlord Trait
Edit: Blood Angel, Dark Angel, Space Wolves, Grey Knights, Death Watch, Cult Mechanicus, Skitarii, Sisters of Silence, Adeptus Custodes and Legion of the Damned are not available in the Castellans of the Imperium Detachment. Didn't notice that... I'm pretty most everything else, including Assassins and Cataphractii/Contempors, are though. Lord of War options are Imperial Knights (specifically the ones from Codex: Imperial Knights) and Baneblade variants.
