So with the arks of Omens Battle Brother/Allied Detachment weirdness, and how you can add an extra patrol of Tempestus (
MT) to an Astra Militarum (
AM) detachment, which in turn can be made up of
MT units, as at no point does it stop you from being an "Astra Militarum Detachment"
Giving you access to 15 troop slot's worth of Scion's
you can guess where this is going
n.b. the exact wording from the codex:
"If every unit in an Astra Militarum Detachment has the Militarum Tempestus, Officio Prefectus and/or Militarum Auxillia keywords, Tempestus Scions units in that detachment have the Troops Battlefield Role, instead of Elites"
Bonus rule, Castellans can have Ogryn Bodyguards. (no other attache, just the bodyguard)
That in turn gives the castellan the Militarum Auxillia keyword, so he can join in the fun as part of the AoO detachment (cant fit in the patrol though, as that is limited to Militarum Tempestus keyword). You can also select regimental doctrines for him to have, as he is the only one using it. So the re-roll 1's to hit aura is here to stay for the wombo combo

1995
so in total, 145 scion bodies. 4 Ogryn Bodyguards 1 castellan.
4 small squads if you need to deepstrike for Retrieve Battlefield Data or leave on a backfield objective out of line of sight
5 pts leftover for a random power fist or Ogryn Slabshield if you think they are better than brute shields, and potential to recover points from the bullgryn plate again for preference.
Or just remove Ogryn's from the commands squads if you think their survivability without them is high enough.
yay power swords everywhere!
All the
CP used to get the Tempestus goodies.
The "bull
banner" from finial, plus warlord traits plus refractor field generator giving out nice 6" bubble of buffs to a big scions blob.
Laurels of command to issue either Take Cover, or Remain Vigilant that one time you really need it in your opponents turn
Okay you are missing any real decent melee punch, there's a lot of toughness 3 units, and a lot of strength 3 shooting, but at least with take aim orders everywhere, things are hitting on 2's (re-rolling 1's near castellan, and re-rolling 1's to wound near flags) and at
AP-3 (Max range Rapid fire and Ignore modifiers if near Warlord command squad, ignoring cover if near 2nd command squad,
AP-4 if at 1/2 range if near 3rd Command squad)
And with ogryn bodyguards and medic's your command squads are sticking around
There could also be some fine tuning with the Voxcasters, as they are nerfed into only having hot-shot laspistol's now, so for the squads you will always have bubble wrapping the command squads (and so always within 6" for orders/inflexible command) it might be worth dropping the vox in favour of another hot-shot lasgun.
