Doesn't sound bad, but the lack of clay/brick in worlds make me not wanna care.
Current fix : Put down some vines where you want mossy bricks and then put some string where you want it to stop growing.
Just something for the time being.
Is there fortune III on shovels?
Could make use on getting more clay if that was the case.
Oh.. ps.. actually there's TONNES of clay in worlds. Just get yourself a bucket, and go to the bottom of the ocean and you'll find tonnes there. The bucket is for breathing underwater so you don't drown.
