DRAGON QUEST BUILDERS

You will be smashing objects right from the start, everything counts, even blocks. Don't worry about this as it will pop naturally.

All smashes are saved to your profile in the background straight away, no need to save. Smashes will transfer between all saves since they are saved on your Profile.

If for any reason, you have the rest of the trophies and this still hasn't popped, load up an end of Chapter save. Then just head out of your base and start demolishing earth blocks with your spin attack, won't take long.

If you run out of materials to craft axes/hammers, rather than farm for materials, exit without saving then reload the save back and repeat.
