Squall ASF
Member
The final mining point has the same haul as the last one in town, but there are some stones you can only get with a max effectiveness hammer (well, max effectiveness + wait three days).
I was able to smash the ones on the main farm by spreading it across a couple days or so haha Maybe stones in later portions of the farm require higher but sounds like this can be low on the priority list. Was there anything you found useful to upgrade besides what I noted in my last post? Seems like the majority of the upgrades aren't worth doing.
