Temple of Discordia

Quezip can resize chaos infused items. This includes chaos amulets.

Hanoma

Jan Li could resize Qith's titanium and glass helm, and seems able to resize a good degree. He was also able to resize my strata gauntlet.

Liathyr

Joreth the armoursmith can resize armours made of Erivelin.

Marte the armoursmith can resize armours made of Steel.

Losthaven

Mallek the armoursmith can resize armours made of Iron.

Anakasha in the fashion shop resizes silk.

Omar Loomis the tanner can resize armours made of Leather. He was able to resize my phylactery of the stars, but just a small degree.

Veruca in the fashion shop. She can resize anklets, and rings as well.

• Veruca cannot resize organic materials.

Note** The fashion shop seems to have quite a few different people who can resize many different clothes and etc. kinda stuff.

Fort Shantaari

Stee Jans the armourer can resize steel, I believe.

Valathyr

Celebrimbor can resize rings of any material, and seems able to resize a high degree.

Camille

Faber may be able to resize silver.

Here is what he responded to a try to resize an AOLP (note that others just say they don't handle things like that, and the inability to resize might be due to the item and my size (tiniest faerie there can be):

Faber examines your silver amulet of life protection carefully.
Faber says, "Your silver amulet of life protection is worth two thousand nine hundred fifty-three gold, Liliet. However, I could not afford to pay you much more than two thousand for it. To have it repaired would cost two hundred gold. I would not be able to resize it to fit you any more closely than it does. To have it evaluated against another item would cost eleven thousand two hundred twenty-three gold, in addition to the cost to evaluate the other item."

Sanctuary

Dubro can resize steel to a minor degree.
