EDIT: NVM found this - On consumption it will give you a buff needed to survive the world boss Nightmare Pilgrim. The Gormak Crystal AlphaWave Inhibitor is the artifice crafted version but you can also buy it directly from a vendor. The vendor version is called Rakata Crystal AlphaWave Inhibitor and costs 30 daily commendations.
The buff lasts 4 hours and through deaths.
