This can be obtained by salvaging the Fractal Capacitor (Infused) created in the previous collection or salvaging another (non-ring) Ascended item. Before unlocking, the achievement has the following instruction text: "To Unlock, Complete Ad Infinitum III, then talk to Kelvei in the Fractals of the Mists."
