Boltgun to Heavy Bolter
Max the Boltgun at level 8, hold a Dice Cube at level 1 or higher, and open a chest that offers an evolution. The result is the Heavy Bolter, described as sustained suppressive fire.
Who starts with it
Brother Luca Amasius and the Black Templars Castellan both open a run with the Boltgun, so this is one of the few 40K lines you can aim at without first finding the base weapon in a level-up. Luca's row in the character tables is one of four unlock notes that disagree: atma.gg marks him available from the start, and TheGamer marks him as a purchase on the character select screen. I keep both readings on the character page and do not let that fight change the recipe itself.
Dice Cube is a passive shared by both universes. Its own cap is level 2, and the max line is plus two attacks. The same cube also evolves the Boltstorm Pistol into the Typhoon Crossbow, so the same passive name appears in two different recipe rows. The published tables identify the required pairing; they do not describe the cube as a consumable or require a second copy. Dice Cube and D6 Dice are different entries: the former is this passive, while the latter is a weapon evolved with Scatter Die. The passive lists do not show one. It is a level-up offer.
The Heavy Bolter line does not carry a published boss-bane tag in the weapon notes I compared. If you want a named Extremis counter from a fist weapon, that is the Power Fist route to the Gauntlets of Ultramar, which the Norn Emissary page points at. Adjacent early guns on the same 40K list are the Lasgun, which wants a Gauntlet instead of a cube, and the Combat Shotgun, which wants a Magnet.
Steam's achievement list does not single out the Heavy Bolter by name the way Ordnance Extremis singles out the Storm Eagle Rocket. The generic evolution achievement Barbecue Hell Yeah covers any first evolution, so this recipe can be that first pop if the cube shows up before Glue does for the Flamer.
