In-game, you’ll find that the Armiger Warglaive has received a bit of an upgrade from its appearance in Forgebane. The reaper chain-cleaver now has two modes of attack. It can make a double Strength and high Damage attacks for taking on larger foes, or a sweeping assault that doubles the number of attacks but hits at the Armiger Warglaive’s regular Strength – which is still more than enough to make a mess of most Infantry units.
This new sweep attack pairs well with some of the Household Traditions in the new codex – getting not one, but two extra attacks with House Griffith’s Glory of the Charge is an obvious candidate, as is House Cadmus, whose Hunters of the Foe ability gives re-rolls of 1s to wound when cutting through units with (comparatively) low Wounds characteristics.
As you might expect, there are a few Stratagems in the codex that are designed to help you get the most from your Armiger Warglaives as well. How about deploying a unit of them behind enemy lines with Sally Forth!, or using Pack Hunters to re-roll charges with multiple Armiger Warglaives. Our favourite might be the simplest – use the Armiger Helverin’s immense speed to move and advance towards the enemy, then surprise them with a charge using Full Tilt, and make the most of that reaper chain-cleaver.
You can take up to three Armiger Warglaives in your force as a single Lord of War choice – and you get two in the Armiger Warglaives set to get you started. It’ll be on pre-order next week and in stores a week later. If you can’t wait that long, Forgebane is still available to buy and contains two Armiger Warglaives alongside an Adeptus Mechanicus army, some Necrons for target practice, and the Warhammer 40,000 rules.
You’ll have to wait a wee bit longer for the last new release to go alongside the new codex. The valiant Freeblade Sir Hekhtur, and his Knight Preceptor steed Canis Rex, will be available later in the year as part of a dual kit that also builds the Knight Preceptor (not to mention every other variant of Questoris-class Knight).
