Dragon Quest Builders Cheats - PS Vita

Infinite Blocks
Once you unlock the Cladding or Flooring for a specific block, use that Cladding to create a patch of that block in dirt. For Flooring each use will yield 25 Blocks of that kind which can be removed from the ground. For Cladding, dig down two blocks and each use will yield 48 Blocks of that kind at max, which can be removed from the ground. Once you've picked up your new blocks you can then create more cladding or flooring with the blocks you created for an exponential increase of the blocks in question.
