I was looking through google images today and saw a cool pallet swap of the Horseman's blade and the Terrablade and I thought that it would be really cool to see the Terrablade craft into a few more weapons. These weapons could still be crafted into the Zenith at some point or you would have to Shimmer the new sword to get your Terrablade back. I think that there could also be a Boomerang, True Melee, and Mace type Terrablade variants. This suggestion is a stretch but I think that it would be a neat addition to this beloved game.
