I got the letter before reaching level 110, so you don't need to beat the new levels to get it. I only had the first 5 of the new levels done.

As with most rocks, this rock is dependent on your attack power. My level 74 character destroyed it with the drill using 360 stamina. That clearly doesn't match this new article.
