Hey there Dasius ! I wanted to tell you my ideas :
-A fancy polearm grip, and a halberd head
-more Two Handed Guards
-gems, so you can put them like runs on the blade or the hammer and make them more expensive.
-Maybe add a dagger grip or blade so it goes better with the grip, because the dagger isnt very beautiful
And that's it. Thanks for reading ! And hope i helped you !
