So I have been stocking up Inferno Rubies in anticipation for whenever epic gems come out (have 6 alchemists to supply) as the raw gems will almost certainly be a mat for epic gems. What I'm wondering though is what the secondary material for the transmutes will be. In Wrath it was Eternal Fires/Life/Shadow/Water/Earth/Air along with the corresponding gem color, but in Cata there is no "Volatile Shadow", which leaves only 5 types of elements and 6 types of gems... Any thoughts on what it might be?
