A weapon evolution needs the correct weapon, its required passive and an eligible chest reward. The release-version table lists level 8 for the ordinary pairs below. That does not establish one universal chest minute or prove that every passive must be maxed.
A focused recipe reference
| Base weapon | Companion | Evolved result |
|---|---|---|
| Chainsword | Tape Measure | Eviscerator Chainsword |
| Lasgun | Gauntlet | Meltagun |
| Boltgun | Dice Cube | Heavy Bolter |
| Nuln Oil | Hourglass | Mordant Earth |
| Whirlwind Battery | Liquid Green Stuff | Orbital Bombardment |
| Frag Grenade | Bandolier | Ripper Pistol |
| Tempest Axes | Sabaton | Whirlwind Axes |
| Nebulous Sea Fog | Bugman's Tankard | Aquatic Illusions |
| Boltstorm Pistol | Dice Cube | Typhoon Crossbow |
| Brazier Staff | Liquid Green Stuff | Master of Runes |
| Rope & Grapnel | White Dwarf | Ghost of Rhea |
These pairs appear in the original October demo report and the separately inspected release table. That is stronger than silently carrying a May-demo recipe forward. The release table also distinguishes retained attacks from replaced weapons; Rope & Grapnel and Frag Grenade are listed as retained.
Before opening another chest
Check the weapon's own level, then confirm the companion is actually selected in your inventory. A level-up offer is not ownership. An ordinary upgrade reward does not by itself mean the recipe is wrong: the release table describes stage-specific chest reward slots. No universal ten-minute shortcut is claimed.
Exceptions matter
Some later evolutions have additional explicit level conditions. Do not apply the ordinary level-8 rule to every special weapon. Fidelis is a separate named chain from Boltgun. Use the installed game's entry if a future update changes an item name or condition.
