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