I realized I have been posting a lot of information on glyphs and such but never showed you the interface for them. My bad. This is a quick update, I just woke up and Spooncraft hasn’t left the station yet so bear with me a lil’ bit. This image is pretty old (from when beta first went live) and it comes form Teza but checking the UI last night on my Death Knight it’s the same.

Has the latests interface as far as i know. 3 major, 3 lesser runes.
some of them are locked and have to be unlocked and if you are an inscriber (person who has inscription as a profession) then you have an extra slot for a glyph.
