To use transformations, including those available to the sub-class, you must complete a quest.

The transformation quest is called More Than Meets the Eye .

1. You can take it from level 50. Starts in Hardin Academy from Hardin .

2. Next, go to Hunter Village . Find Errickin in the Dark Elf Guild .

3. He will ask you to get Mirror and Forest of Mirror Ghost in Forest of Mirrors . Hunt them until you have 35 units of ectoplasm .

4. Return to Errickin and get stabilized ectoplasm . Then go to Hardin Academy to Hardin , where you get the transformation instructions . Then fly to Dion and talk to Magister Clayton in the dark elf guild .

5. From Dion we go to Plains of Dion , where we find Glass Jaguar not far from MDT . Kill them until we collect 5 Glass Jaguar Crystal .
