Whether you command Astartes, Mechanicum engines, or the rank-and-file of the Auxilia, this update smooths gameplay and clears up some long-debated grey areas.
Let’s break it down faction by faction, with some practical insight for your next Age of Darkness battle.
New Horus Heresy FAQs & Legacy Army Rules:
Updated on October 30th, 2025, by Rob Baer with the latest rules FAQs.
The new Horus Heresy FAQs & Legacy Army Rules updates come from Warhammer Community.
Core Rules: Smarter Reactions, Sharper Shooting
You can now make 0-cost Reactions even if your allotment’s hit zero. That means you won’t be left totally helpless when your opponent’s barrage starts. On the flip side, Heavy and Ordnance weapons stay grounded; if they’d lose their Defensive Weapon status from a Strength bump, they’re out of bounds for Reactions.
Line of Sight Shenanigans
Alpha Legion’s Lies and Obfuscation won’t bend the rules of sightlines anymore. Terrain behaves as normal, so your enemy can’t claim their bolter shells hit “in spirit.”
Vanguard (X) and Victory Points
The designers clarified when Vanguard (X) triggers: you score those points only if your opponent’s last model in a unit dies. Blasting the ones holding an objective doesn’t count unless it wipes out the whole unit. Brutal, but fair.
Gun Down, Not Run Down
No more tagging a unit that’s just Disengaged with Gun Down or Pursue aftermaths. They’ve already slipped away; you’ll have to catch them next turn.
Psychic Powers: Resistance Is the New Normal
The psychic phase got a tidy overhaul. Instead of Manifestation Checks, many powers now use Resistance Checks, giving targets more consistent ways to defend against brain-melting effects.
- Mind-Burst now scrambles Statuses, triggers a Fall Back, and might rout the target if they flunk their Leadership test.
- Tranquillity drops enemy Willpower by 2 and softens their psychic weapon Strength by 1.
- Seal the Veil tightens up Set-Up moves and makes Charges riskier; discard your highest die if you fail that Resistance roll.
The psychic phase now feels more interactive and less like a “hope you roll low” moment.
Flyers and Firepower
Flyers can now move through vehicles without causing hits, but they can’t trigger Death or Glory Reactions. The Combat Air Patrol reaction also got a full rewrite; your reacting flyer can shoot with all weapons as Defensive Weapons.
Weapon tweaks include:
- Forge-Crafted Heavy Flamer now sits at AP 4, giving it a bit more sting.
- Perdition Weapons are now clearly defined as Blades, Axes, Mauls, or Spears.
- Hellstorm Templates now have an official range of 16″, clearing up years of confusion.
Mechanicum FAQ Changes
Mechanicum players get a nice mix of flexibility and structure. You can now ally Mechanicum detachments, but they can’t share the same Faction Trait, no double-dipping with Reductor or Cybernetica tricks.
The Arcuitor Magisterium finally gains extra weapon choices to match its model, and the Lord of Automata grants an extra Force Org slot for your Castellax units.
And a rules fix for mixed units: if Automata share a squad with organic leaders, Leadership checks use the squishier model’s stats. No more passing just because you’ve got a robot buddy.
Legiones Astartes Updates & FAQs
The Moritat joins the Bitter Duty club, meaning they can finally hang out with Destroyers without anyone calling HR. The Paladin of the Hekatonystika gains the Order Exemplars rule, Dark Angels fans, that’s a subtle but flavorful bump.
Prime Slot rules get a restriction: if your Prime Slot unit includes a Unique model, you’re limited to Special Assignment or Logistical Benefit Prime Advantages.
Legacies of the Age of Darkness 1.1
The Legacies PDFs also received an overhaul that goes beyond fixing typos. If you find your favorite unit here, it means it’s not tournament-legal, but at least you have rules for all your home games.
- Cassian Dracos now rocks twin Gravis Power Fists.
- Moritat Mortalis gains Bitter Duty to stay in line with the main errata.
- Caestus Assault Ram matches other flyers with a single Armour Value.
- Talons of the Emperor clean up confusing text, Constantin Valdor correctly grants extra Reactions, and Magisterium Vexilla only affects enemies.
- Imperialis Militia Provenances of War can’t stack multiple Cool bonuses (sorry, leadership spam fans).
- Salamanders Inductii Master officially gains the Sergeant Sub-Type.
Final Thoughts on Horus Heresy FAQs & Legacies
