Why a weapon will not evolve

A weapon will not evolve until its required level, companion passive and chest reward type all qualify. First check the passive’s exact name and level, then the chest. Raising an ordinary level-one companion to maximum does not turn an upgrade-only reward into an evolution.

Fix the missing requirement

Weapon or result	Required correction
Power Klaw → Bale Eye	Power Klaw 8 and Da Lucky Stikk 9, its maximum.
Power Fist → Gauntlets of Ultramar	Power Fist 8 and Codex Astartes 6, its maximum.
Ardent Blade → Weapon of the Matriarch	Ardent Blade 8 and Tactical Rock 9, its maximum.
D6 Dice → Sustained Fire Dice	D6 Dice 8 and Scatter Die. Dice Cube belongs to other recipes.
Uskavar → Ghal Maraz	Uskavar 5 and Null Pendant 5. Tactical Rock only completed the preceding hammer step.

For Chainsword → Eviscerator Chainsword, Tape Measure at level one is enough once Chainsword reaches level 8. Check the full evolution reference before spending additional level-up choices on a passive that already qualifies.

Imperial Bastion has early evolution rewards

Imperial Bastion’s minute-one boss reward has an evolution slot. Its minute-three, minute-four, minute-six and minute-eight boss rewards instead begin with existing-equipment upgrades. Evolution-capable rewards return at minute ten.

A concrete failure is therefore possible: a completed Chainsword 8 + Tape Measure recipe can receive an ordinary upgrade from an intermediate Bastion reward. Keep the recipe and seek the next eligible reward; the passive is already sufficient.

The minute-one opportunity does not imply that a new character can always finish a weapon by then. It identifies a reward type, not a guaranteed early build.

Gallowdark’s minute-five Plague Marine reward can also contain an evolution. “Wait until ten minutes” is therefore an unreliable rule across all stages. The Imperial Bastion and Great Parch guides list their own wave schedules.

Open the chest after completing the recipe

An eligible reward cannot compensate for a weapon that still needs levels. Finish the weapon and its actual companion before collecting the chest you intend to use for the evolution. Chest color alone does not establish its reward type.

Level-up choices explains the separate weapon and passive slots. If the missing problem is XP rather than the pairing, use XP collection and Kozlowski.

Unreachable chests after hotfix 2.1.6

Steam hotfix 2.1.6 fixes chest drops outside reachable space on Gallowdark and Imperial Bastion. It also allows any input to skip the chest sequence. The developer released those changes on Steam first, with GOG, console and mobile updates planned for the following week.

If a chest sits beyond a wall, check the platform version. More passive levels will not fix an inaccessible drop. The hotfix page separates that collection problem from an incomplete recipe.
