Some very curious details are observable in these cases of malformation, For instance, the Aecidium eta/mum first referred to causes the new shoots to differ in direction, duration and arrangement, and even shape of foliage leaves from the normal; and the shoots of Euphorbia infected with the aecidia of Uromyces Pisi depart so much from the normal in appearance that the attacked plants have been taken for a different species.
From the 6.2 PTR Patchnotes: Shadow Shadowform no longer applies its visual effect to the Priest's mount. Glyphs Glyph of Shadowy Friends now extends Shadowform's visual effect to the Priest's mount in addition to non-combat pets. Has someone asked for this change? Why fix what was not broken. Shadowform extending to my mount for me is part of the flavor of the class/specc. And no, I don't want to use a glyph to have what was baseline for the past 10 years. And I don't want to put my battle pets in shadow form either.
Some agates exhibit a shadow effect in which there is what appears to be movement across the agate layers when the specimen is rocked back and forth (or your orientation to the specimen moves). This optical effect only occurs when there are alternating translucent and opaque bands.
