Blacksmith of the Sand Kingdom

To get this achievement you need to gather materials from the gathering nodes on the map 1000 times. To do so simply go up to the node (big black rock that sparkles) and hit the A button.

At first you can only gather once from each node each time you go into the dungeon. Though there are upgrades you can get, such as the legendary pickaxe from the store for jewels. This allows you to gather three times per node per run of the dungeon.

Eventually you will get a class called the Explorer that has an ability that shows the gather nodes on your minimap.
