The new Black Templars codex is coming to pre-order this weekend from Games Workshop. As is their custom, they're showing off previews from inside the book as the week goes on. This time around, it's showing off the religious zealotry of the Templars and the various Vows that they can take when going into battle.
From the article:
If you caught our latest Sunday Preview, you’ll be acutely aware that the mighty Black Templars Army Set is up for pre-order this weekend. It comes with a shiny new codex supplement (complete with an exclusive cover, no less), and in it you’ll find all the awesome knightly rules you could possibly hope for.
Foremost among the new rules are the Templar Vows. Long-term squires of the Chapter may remember these from when the heirs of Sigismund first burst onto the scene in Warhammer 40,000’s third edition. Well, Templar Vows are back and more binding than ever! Let’s learn a bit more about them.
