Match your weapon to its passive
The October demo has 11 unique community-reported evolution recipes, shown below by setting; Nuln Oil and Hourglass produce Mordant Earth in both universes. To claim an evolution, raise its base weapon to level 8, carry the matching passive, and open an eligible boss chest.

Age of Sigmar evolution chart
| Base weapon | Passive to carry | Evolution result | How to obtain it |
|---|---|---|---|
| Tempest Axes | Sabaton | Whirlwind Axes | Maximize Tempest Axes, carry Sabaton, and open an eligible boss chest. |
| Nebulous Sea Fog | Bugman’s Tankard | Aquatic Illusions | Maximize Nebulous Sea Fog, carry Bugman’s Tankard, and open an eligible boss chest. |
| Boltstorm Pistol | Dice Cube | Typhoon Crossbow | Maximize Boltstorm Pistol, carry Dice Cube, and open an eligible boss chest. |
| Brazier Staff | Liquid Green Stuff | Master of Runes | Maximize Brazier Staff, carry Liquid Green Stuff, and open an eligible boss chest. |
| Rope & Grapnel | White Dwarf | Ghost of Rhea | Maximize Rope & Grapnel, carry White Dwarf, and open an eligible boss chest. |

Ripper Pistol and Ghost of Rhea are gift evolutions in the demo. Ghost of Rhea lets you retain Rope & Grapnel, and players also describe receiving Ripper Pistol while keeping Frag Grenade. These outcomes can add an attack rather than simply replacing the original weapon.
Prepare the pairing before opening the chest
- Choose the recipe for your setting and acquire both the base weapon and its matching passive. Check the item names against the chart before committing further upgrades.
- Raise the base weapon to its maximum, level 8. Carry the matching passive; the October-demo route allows the passive at any level.
- Wait for an eligible boss chest with the ingredients ready. Reliable evolution opportunities begin from minute 10 on Imperial Bastion and minute 7 on The Great Parch.
- Open the chest to claim the evolution. An early chest, or one opened before the ingredients are ready, may award ordinary upgrades instead.
- Find the Munitorum Dataslate and Warscroll to open their respective Armouries. The Armoury records evolution recipes, giving you an in-game reference for future runs.
Check starting weapons and rescue requirements
Malum Caedo and Neave Blacktalon start unlocked, carrying Chainsword and Tempest Axes respectively. Imperial Bastion contains the rescues for Trooper Bartosz Kozlowski and The Legend of Catachan. The Great Parch contains Ulgromthier and Lyssa Revenya.
The evolution objectives for Meltagun, Ripper Pistol and Master of Runes require rescuing Kozlowski, The Legend of Catachan and Ulgromthier respectively. When planning these routes, check the rescue requirement alongside the weapon and passive. Starting a pairing is easier when its access requirements are already handled.
Replace outdated May demo ingredients
| Weapon | May demo companion | October demo companion |
|---|---|---|
| Whirlwind Battery | Tape Measure | Liquid Green Stuff |
| Nebulous Sea Fog | Glue | Bugman’s Tankard |
| Boltstorm Pistol | Lightning Bolt | Dice Cube |
Weapons without a demo evolution
Grandblade, D6 Dice and Power Fist have no evolution in the demo’s documented recipe list. D6 Dice is also separate from Dice Cube, the passive used by Boltgun and Boltstorm Pistol. Keep those names distinct when choosing ingredients for an evolution.
Specific recipe and unlock questions
- Which passive evolves Nebulous Sea Fog?
- In the October demo, pair Nebulous Sea Fog with Bugman's Tankard to obtain Aquatic Illusions. Its evolved effect is a damaging, slowing field that periodically summons illusions which draw enemies inward and retaliate. Obtain the Warscroll to open the Age of Sigmar Armoury, then check the recorded recipe before maximizing the weapon and opening an eligible chest.
- How do I get Bandolier for the Ripper Pistol route?
- The demo discussion links Bandolier’s unlock to leveling Boltgun. Check your Objectives for the displayed target before planning the Frag Grenade pairing. Once Bandolier is available, select it for the run and build toward the recipe in the chart.
- Does Bandolier have to be maximized?
- A player reports obtaining the Frag Grenade evolution with Bandolier at level 1, and the October-demo evolution route allows the matching passive at any level. Focus on maximizing Frag Grenade while keeping Bandolier equipped before opening an eligible boss chest.
- What happens when Power Fists summon Marneus Calgar?
- Auroch Digital’s announced evolution brings Marneus Calgar alongside you to attack with the Gauntlets of Ultramar, unleashing bolter fire with each strike. The developer makes an exception for runs already played as Marneus Calgar. Keep this announced outcome separate from the October demo chart, which has no Power Fist evolution recipe.
Keep developer showcases separate from demo recipes
Auroch Digital has explicitly shown Whirlwind Battery becoming Orbital Bombardment and described Boltgun becoming Heavy Bolter. Its developer article also shows Fidelis evolving into Purgator Mirabilis, adding the Paragon Missile Launcher alongside the bolter fire. Rope & Grapnel gains Ghost of Rhea, whose banshee attack bursts into damaging ghostly fog.
The charts above remain scoped to the October demo’s community-reported pairings. The broader developer showcases describe evolution outcomes, including attacks beyond that demo chart. Demo progress does not transfer to the full release, so use the release build’s own recipe entries when planning a new run there.
