Question about scroll mechanism

Hi guys,

Maybe someone can help me out.

Actually we all know we can obtain the scrolls in different ways, altho im tryng to figure out how to get back to the original aspect of that item without donate for the scroll of purify. Let me show u my own situation

I've trasmoged my S8 Holy Paladin Shoulders into the Tier3 ones,
Now i want to have the S8 original shoulders looks.
I've used the trasmog scroll on my s8 shoulders, so right now i've the essence in my bag, altho when i try to set it up on my shoulders it says i cant.

So question is, how i can get back the original aspect of an item without donate to buy the purify?

Thanks a lot , hope someone can explain me.

Put 2 and 2 together...

If you want your s8 holy paladin shoulder look again you need to buy the s8 "retri" shoulders and use the transmog scroll on those, then apply it to your "holy" shoulders.
