2) a Scythe: a new look for the Rocket Hammer. I realize you'd have to buy the expansion, but the idea of a scythe seems to fit with the movements and sprite already there for the Rocket Hammer. Sort of like the scissor blades were a new Leviathan Blade.
- maybe obtainable as a trade in mission reward for a Rocket Hammer?
*any suggestions on a better way to acquire the scythe are truly welcome.
