The gold smithing/mining armour?

With the feather on top of the helmet,what is it called?

 

Its a pretty new update from a few months back. You can get the full set in the "Lava Flow Mine". It does take a couple of hours to get it.

 

does it give mining boost in exp? im just winging it but wasnt it x2 with full set? at the lava mine only or something like that?

 

Full set increases mining exp gained by 2.5%.

 

It's epic, you should get it. I got it an it comes in very handy.
