I've been working on Allegiance abilities for the Cult of Mars. So here's your sneak peek.
Because Cult of Mars is two factions from 40k rolled together, the battle traits are Doctrina Imperatives, along with a new one I invented wholesale called "Rites of Reassembly". The Rites of Reassembly are basically the Death battle trait. The Cult of Mars is a very priest-centric faction, so they've got their own list of special prayers.
I've got to finish up Command Traits and Artefacts and give the whole thing another pass for typos, but we're almost there!
