Geologist's Ledger - Overloaded Elements

To complete this achievement you need to use Elemental Overload on the following elemental deposits: Hardened, Primal, Molten, Titan-Touched, Infurious (WM ON) and Metamorphic. You can check your progress in Appendix II - Overload of your mining journal (it's at the bottom). If it's missing from the list, you're missing it from the achievement progress :)

Overload Elemental Deposit is in your Spellbook. It's not in your mining journal.

To get Geologist's Ledger - Overloaded Elements you need to have each of Hardened, Molten, Primal, Titan, Infurious, and Metamorphic Overload learned.
