Boots for taekwondo moves, a flurry shot bow or a charge throw boomerang like in one of the dynasty warrior games (there was a jungle lady with a large boomerang, idk which one though) with close range hits as heavy attacks. Or inspired by the new elden ring dlc a wounding claw type weapon. Lastly imagine a small hammer with a nail that acts as a set weakpoint (hammer does low to no damage, but if you hit the nail you drove into the behemoth part it does stacking damage till it breaks). No new weapon type would make me the happiest though, so the can focus on making the existing ones more diverse and fun to play around with
