Blunderbuss (no reason to have since the Grudgeracker is already present), I could have put it in the previous category but I think it’s too similar to the Grudgeracker
Doomseeker: Axes spun upon chains
Drakegun Skolder gun: Steam instead of fire, better range ?
Hammerer’s Hammer (2h and 1h with Shield)
There are still a few Axe/Hammer and Picks weapon that could work,
Axe-Gun: TW Warhammer 3’s Kislevite faction changed the Streltsi’s weapon (An Handgun and a Bardiche) into a combined Axe-Gun, it could work as a Mixed melee weapon
Fireglaive: From the Chaos Dwarf Armoury, being a repeating handgun with an Axe head
We won’t see it, but my pick would be a Cog Axe. We got a disappointing Coghammer with the Outcast Engineer update that is the lamest sort of steampunk weapon, what with its random spinning cogs and apparent steam-powered . . . nothing. The Warhammer equivalent of putting some cogs and gizmos on a top hat.
Give us a big spinning cog on the end of a grip. Let the special be revving it up so it can hit multiple times, like a Fantasy version of the chain- weapons in 40k.
Well Doomseeker come from a particular side of the Dwarf Culture (The 3 main sides being: Runes/Ancestor; Engineering and Grudges/Honour)
Slayer are dwarfs who have cause such shame that only their death may absolve them, but that death must be earned and a bad Slayer is one who keep surviving, making it so that Slayer often leave on hunt (Troll->Giant->Dragon->Deamon Slayer) to their dooms.
Doomseeker are a weapon most wouldn’t use, it’s difficult to use and dangerous but more importantly, Slayer and Dwarfs as a whole have different anatomy to the Human and the elfs, having much more strength
The difference btw a Doomseeker and a Flail entail on how it work, Doomseeker can be used in pair, and are on longer chains, like a Kusarigama
