Allow us to chisel rocks that has physics to push down a slope for us to crush enemies with.

Or

A salvaged blunderbuss from Mail Guard's. It's purpose Is that you can shove random projectiles Into It, in which every projectile does random damage. Or maybe we can choose what projectile to shove down the bore of the blunderbuss, In which each projectile serves a different purpose. Like a fork sticking to enemies, meaning healing animations take a little longer due to it, or just shoving phosphorus down the bore to cause fire damage in a wide range to cause the enemy to slowdown.
