Is their hidden skills for these?

I have heard minning has it and some people say it doesnt have any skill lvl.

Choco I only heard that it does have skill lvls.

Lastly harvesting I never done it so I dont know anything about it.

Any input!

From what I've heard again and again there are no hidden skills for mining, harvesting and logging.
There is for chocobo digging though.

This is why +mining etc gear is so important.

yeah asl18fs is right i know someone who is level 8 chocobo digging and i also know someone who is level 10 chocobo digging. 10 is highest you can get.

If your lvl 10 chocobo digging. You you get more rare items or is it just more items and less misses.

The delays when digging is reduced.
You may also get better items.

However, I doubt they go around the digged item spawn code.
