Onyx Ore

Dropped by the Goblin King Field mob, Onyx Ore was recently added into the game along with the Goblin King for the Will of Mimir patch, so each elemental would have its own unique ore.

Like the Sapphire Ore, Onyx Ore is solely for weaponry and cannot be added to armor except as a cosmetic enhancement. It's latent power charges up just like the other elemental ores do, but it charges a little faster, as Darkness is sadly the weakest elemental of the game, only really useful against the early-level slimes and possibly goblins if the user is strong enough to handle them. This could change in the future as more uses are discovered for Onyx Ore as they become more readily available for the playerbase.
