The Fabled Crystallized Shadow Tunic has a race restriction that does not let the following races use it: ELF HIE HEF DWF HFL
Regular non-fabled Crystallized Shadow armor has the same restriction, however the regular Crystallized Shadow armor can be combined in the Kejek Forge with a Soulforge Hammer to create Purified Spirit armor, which is wearable by all races.
The Fabled Crystallized Shadow Tunic does not turn into a Fabled Purified Spirit Tunic when combined in the Kejek Forge. I am thinking the fabled tunic should be fixed one way or the other.
