As the title says, what is new about mining?
As far as I know there is a few new things like, more mine levels, other requirements for mine holes and some new ore called "Peacock".
But there is still some questions that for me are unanswered:
Are there more new ores than peacock?
How many mine levels are max now, and what are the requirements for level 6 and deeper, (7,8,9?)?
Have they changed slime walls? So far I have not mined out a single slime wall for mine level 1-4 and I have mined quite a bit.
Any new creatures lurking in the lower levels? So far I've seen cave lice, cave snail and the angler fish monster thing.
What determines the cap on Q on mining stone tiles and ores? I have a q90 tool and 90 Maso, what's the hard/soft cap of ores/rocks?
