The Craftting Recipe
The Thaumium Leggings has high durability and is far more enchantable than the Gold Leggings (Most enchantable Armour in Vanilla).
All pieces of Thaumic Armour are stronger than their Iron counterparts.
This is made up by the fact of its high enchantability.
All pieces of Thaumic Armour are crafted like Vanilla Armour except with Thaumium Ingots.
