Basically, I asked if, until they publish an update, the updates from Codex: Astra Militarum applied to any Renegades and Heretics units where the entry in the Forge World Index just says to refer Index: Imperium 2... and they said yes. So things like their Leman Russ and the like are supposed to use the updated rules, but currently in Battle scribe they don't.
Allow me to show you the Sisters of Battle Codex...oh, wait.
Let's see...let me find Imperial Agents, nope, not a full codex. Hold on lemme download that PDF or find that WD article. Hmm...no dice. Wait, here we go! Coming to you live all the way from 3rd Edition, it's Codex: Witchhunters!
yeah, I am thinking of a Primaris apothecary with a magnetised pauldron so he can be either Deathwatch or Dark Angels
my points didn't change much, apparently I'm down to 4,387 points - but that is still a massive collection considering I've had my Eldar since the dawn of time (about 20 years...) and I only started my Deathwatch a year ago
