Thanks for clearly identifying yourself as blockworthy. I was gonna give you the benefit of the doubt, but you just couldn’t resist outing yourself could ya?

These are faulty full body invisible spells, that are heavily discounted, because they work only on the helmet. Because of the difficulty to create a full invisible spell, the majority created are faulty and basically trash, but mages sell them for low price to get back at least the material costs. Low yield.

Now you’ve got me imagining a budget version of an invisibility potion/spell/item that gives 30% translucency.
