Level 80 Stately Armor?
if you can post the link to the original set, finding a duplicate will much easier. many of the PvP sets are also available through WvW. you will need to use fine transmutation stones, which you can get through the gem shop or from black lion chests. the ‘of hoelbrak’ part doesn’t matter, since that just tells you what rune is in it, and you can replace that easily.
You need Fine Transmutation Stones to transmute with level 80 gear.
If an armour says “- of soandso”, that refers to what rune it is using. When you transmute, you can chose to keep that rune as well. Or you can chose not to, and put your own rune of choice into the upgrade slot.

I was able to get the set’s name after some googling and a few hours, then wiki’d it on the site.
