I made some Slight Glyph of Magicka that's suppose to "Adds 34 Max Magicka" to armor, but when I add it to my level 24 armor, it only adds 13 magicka. The glyph is intended for item between level 15-25 so I didn't think my 24 armor should be a problem. Is that a bug or working as intended? What's the point of creating a blue glyph if it doesn't work that well?
