This is part of the teir armor for the TSS expansion. It works much like the Gates armor does - you get an armor mold as a drop from a named, get another few essential items (in this case, 4 frosted scrap metals) and you turn them in to an NPC in Cresent Reach. Depending upon your class, the pieces you need are slightly different.
In the case of paladins here, for this particular piece you need the following:
An Ancient Chestplate Mold (WAR CLR SHD PAL BRD ) - drops from Tarnuk Farwalker in Icefall Glacier.
Once you have that, being a plate class, you need 4 Frosted Scrap Metal. These drop at various places in the new expansion, and are tradeable, so check the bazaar. Right now on Tunare they're selling for a few hundred plat.
Take your mold and 4 scrap metals to Tenish in Cresent Reach. He can be found just up the ramp next to the Librarian (do a find for the librarian and go up that ramp on your right.) The tricky part here is that you have to hail him and get the quest for the specific piece that you're wanting to make. He gives you the choice of all the armor pieces. And yes, you can get the quest AFTER you have obtained all your items. Once you have the quest, hand it to him and voila!
The next step in increasing the power of these pieces of armor is to obtain a particular powersource that drops from the higher zones (Ashengate and Valdehorn, for example.) In this case, the plate classes need "A Faintly Glowing Powersource". Once you have the proper powersource, take your armor and the powersource, get the appropriate armor piece quest from Tenish again and then hand in the armor and the powersource. Viola! Upgraded armor!
IMPORTANT!!!!: TAKE OUT ANY AUGS BEFORE YOU HAND IN THE ARMOR!!! (yes ou can do that in cresent reach too, do a Find for the "solvent" merchant.)
Several people have linked to this information for many of the other armor pieces for all classes, might as well link it here. Great resource:
