This is on Blight. I purchased a few Armor and Scale Dye Kit: Invisible today and started putting them on some of my armor. When I went to equip the armor I was told I didn't meet the requirements. After inspecting the armor I noticed that the application of the techs also put on a race restriction. The only usable races are Saris, Sslik, Satyr, and Dryad. Kinda bummed because I am a Half-Giant. I bought ten other colors that were for sale also and none of them had the racial requirement after application. Inspecting the tech itself doesn't list any racial restrictions either. I'm hoping this is a bug.
