Where is the New Primal Storm Weapon Enchant Illusion?

Hoping that they add another lightning/electrical arc illusion to the game at some point. There’s a pretty notable lack of them in-game, but we’ve got plenty of fire and frost illusions. Some of the gear in Undermine would be perfect with something like it. Steampunk, goblin/enginner, elemental, etc mogs would benefit from it a lot.
