Over the course of the story, you’ll unlock Ionic Powers that you can use. You'll unlock your very first Ionic Power, the Ionic Vortex during the story mission, "Storm's Coming". The other Ionic Powers will also be obtained as part of the story, but will be dependent on which karmic play through you're on.
These are activated by pressing on the D-pad. In order to use them though, you’ll need to collect Ionic Energy, which is represented as glowing purple orbs that are occasionally dropped and can be picked up from defeated enemies.
Use any of the Ionic powers 30 times, and the trophy will unlock.
