The Power Fist combo is Power Fist + Codex Astartes = Gauntlets of Ultramar. This is the full-release recipe; do not treat an older demo's missing evolution as a restriction in the released game.
Identify Power Fist
Power Fist and Power Klaw are separate weapons. The latter belongs to a different recipe and does not become Gauntlets of Ultramar by adding Codex Astartes.
Assemble Gauntlets of Ultramar
| Ingredient or result | Item |
|---|---|
| Base weapon | Power Fist |
| Required passive | Codex Astartes |
| Evolved weapon | Gauntlets of Ultramar |
- Obtain Power Fist or start with its associated champion, Marneus Calgar.
- Take Codex Astartes as the required passive.
- Upgrade Power Fist to its maximum state.
- Open a boss-dropped chest with the pair equipped.
The passive named Gauntlet is not Codex Astartes. Gauntlet is used in the Lasgun evolution, even though its name sounds closely related to the evolved fist weapon.
Understand Calgar's appearance
The evolved Gauntlets of Ultramar unleash bolter fire with their attacks. If you are not already playing as Marneus Calgar, evolving Power Fist can bring him alongside your champion to wield them.
That is part of the keyword and follower system. Acquiring a weapon your selected champion cannot wield can add an ally who uses it on your behalf. Followers attack without taking damage or collecting items, so you do not need to protect Calgar as though he were a second player with a separate health bar.
Check the recipe before changing the build
For a stalled evolution, first confirm the exact three names: Power Fist, Codex Astartes, and the expected result Gauntlets of Ultramar. Then check the weapon's upgrade state and pursue a boss chest. A large squad, a high character level or a similarly named passive does not replace the required pair.
