===Shield of Baal: Exterminatus===
*'''Conclave of the Burning One:''' Two Crypteks must join a Transcendent C'Tan.  On the plus side, you get to use the shard's beefy T7 when rolling to-wound against this.  The Shard also gets 5+ FNP, which gets dropped to 6+ FNP if a Cryptek dies and leaves altogether if the Shard is left alone. That said, stick the God Shackle on this and the whole unit gets T8!
**This can be an absolutely amazing formation, for starters it's very minimal, if you were going to field a Transcendent C'Tan anywhere in your army you should consider saving the Heavy Support slot and taking this instead. 
**Veil of Darkness would allow you to teleport a C'Tan to where you need it most.
*'''Zarathusa's Royal Decurion:''' Overlord, a unit of Immortals, 2 Warrior squads, A Ghost Ark, a Doom Scythe, Praetorians, a Stalker, a squad of Deathmarks, and 2 squads of Wraiths, all assembled in a mini-army.  The Overlord gets to give the non-vehicle units Crusader, Counter-Attack, Fearless, or Monster Hunters for a turn.  That said, if he leaves, the formation loses these rules too.
*'''Anrakyr's Royal Decurion:''' Anrakyr joins a unit of Immortals (which you should upgrade), 2 Warrior squads, A Ghost Ark, a Doom Scythe, and Deathmarks.  Sadly, all you get is a re-roll on Seize and a re-roll on Reserves while Anrakyr's still alive.
*'''Guardians of Perditia:''' All formations slapped together.  Everything's the same as it is, and the overlord of Zarathusa's formation also gets to give the special rules to any unit in this mob.
