I know he doesn’t have any magical weapon but he may have access to some of them with a Dlc career. I don’t really know what battle Book/Codex to look at, there could be variant of Kruber’s weapon, exotic weapons (A Witch Hunter could have access to a Scimitar, a Tulwar or even weapon from Cathay and Nippon), Magical weapons, nobles weapon or more “unique” weapon (Such as an Axe Gun)
My man’s getting 2 new weapons with his new class, to follow the trend. That will most likely mean one wep all Saltzpyre’s can use and one unique.
Whichever weapon ends up being on all classes I hope has the same flair for the unusual the rest of his arsenal has.
There’s a lot of weird ones out there. Punch blades, spring loaded daggers, ect. Realistic warhammers and warpicks are so underrepresented in fantasy that they’d probably look esoteric next to Kruber/Bardin.
