Probably lots of simple machines like... Wedges, pulleys, and levers mostly. With magic properties making those machines 更多 efficient, I can imagine them producing quite amazing results. Stone robots, stone cars with wheel system. Stone aircrafts made of woods and stones powered 由 magic crystals 或者 magic stones 或者 some sort of energy system. Stone swords, shields, stone robot 龙 made of complete stone, clay and wood technology.
