Lasgun + Gauntlet = Meltagun. For a direct starting route, choose Trooper Kozlowski, whose starting weapon is Lasgun.
Identify the base weapon
Lasgun fires at the nearest enemy. As it gains levels, additional Cadian squadmates join in with their own small-arms fire. This is part of the weapon's behavior, so extra soldiers appearing alongside you do not mean the evolution has already occurred.
Get Meltagun
| Recipe role | Required item |
|---|---|
| Base weapon | Lasgun |
| Passive | Gauntlet |
| Result | Meltagun |
- Start with Kozlowski or obtain Lasgun during a run.
- Take Gauntlet as the matching passive.
- Keep upgrading Lasgun until it reaches its maximum upgrade state.
- Open a boss-dropped chest with the recipe equipped.
- Check for Meltagun, rather than assuming any Lasgun upgrade is the transformation.
A character-level increase and a weapon upgrade are separate. If the recipe is not triggering, look at Lasgun's upgrade state and your equipped passive before spending time chasing a particular character level.
Keep the passive names distinct
Gauntlet is the ingredient for Lasgun. Codex Astartes belongs to Power Fist's evolution; the similarity between a gauntlet and a fist does not make them substitute ingredients. Dice Cube is used with Boltgun, another firearm with its own route.
Understand the squad interaction
If your champion cannot wield an acquired weapon because of its keywords, an appropriate follower can use it on your behalf. Followers cannot take damage or collect items.
Kozlowski's extra Cadian troopers also have a specific interaction with the Black Templars' Castellan, whose attack power and skill improve as followers are added. That squad interaction is separate from the Lasgun-to-Meltagun recipe; it does not replace Gauntlet or the required weapon upgrades.
