You should make it that fortune effects blocks
Example: If you mine an Iron Block with Fortune 3
You'll get 3 Iron Blocks
I don't think this is a good idea since there's lapis from M->O+, you can mine lapis lazuli(s) with a fortune III pick and collect as many as you can and craft them into blocks, I don't think Fortune III should turn an iron block to 3 of em.
The price of success is hard work, dedication to the job and determination that whether we win or lose, we have applied the best of ourselves
