I don't know if this is something that was already thought of but discarded so here goes.
I want a wand or orb or something that can turn dirt to stone. It can be sold by the traders and go for between 5-50 silver per tile if anything, then maybe we can have places that are not shear cliffs on the PvE server because people dug out looking for stone. I think this would help the game a lot after all I know I cant be the only one that has fallen in to random pits because people dug for stone and never put the dirt back, this could help with some server problems (I think at least).
