Mining Pick

In order to mine ore, a character must have an item that counts as a mining pick in inventory.

The Mining Pick item is the definitive and original mining pick. Patch 2.0 flagged a number of weapons to also qualify as mining picks, and several other items since them have been added that similarly qualify as mining picks.

This item can be bought off of most Trade Goods vendors or Mining Suppliers.
