Multiple launch-week guides list this pairing. This is a source cross-check, not a claim that this site tested the recipe in game.
How do you get Purgator Mirabilis?
This pairing is for Warhammer 40,000 runs. A familiar passive can lead to a different recipe in the other universe, so check the universe label before building around it.
Purgator Mirabilis evolution checklist: use the Fidelis, carry Golden Demon at any level, and open a boss or elite chest. This is the core requirement set for the Purgator Mirabilis evolution in Warhammer 40,000 runs.
- Base weapon: Fidelis; max level is required before its evolution step.
- Passive: Golden Demon at any level.
- Chest: a boss or elite chest after the requirements are ready.
- Result: replaces the base weapon (standard evolution).
Step by step
Keep the weapon, passive and eligible chest requirements in view together. A matching weapon and passive do not trigger an evolution by themselves; the chest is the final step.
- Level the Fidelis to max. Most weapons max out at level 8.
- Pick up the Golden Demon. Any level works, so you do not need to upgrade it.
- Open a boss or elite chest. Kill a boss or elite enemy and open the chest it drops. If the weapon and passive are both ready, the chest gives you Purgator Mirabilis.
Other weapons the Golden Demon evolves
- In Age of Sigmar runs, the Golden Demon evolves the Twin-Tailed Cat into Enchanted Glove.
