Forged Finery

Right now in season 1 you can earn this achievement by purchasing a full set of honor armor from Velerd (55,76) in Dornogall for honor. For me as a leather wearer the armor set is under Hallowfall Leather Armor -> Aspirant (might be something else if you are alliance or cloth/plate). If you buy a piece of honor armor you can click on the message in your chat to see the set.

You need 6475 honor.

Gotchas:

• 
  
• To make the achievement pop, you must equip each piece, such that they are no longer refundable.
• 
  
• If the pattern from previous expansions holds, once season 1 ends, this achievement will become unattainable until the next expansion, when this gear will be purchasable for Marks of Honor.
• 
  
• Be very careful about what cloak you buy. For me there were four cloak choices, but only one of them completed my set.
• 
  

If you are looking to get easy honor, the Comp Stomp Brawl is a good choice, when it's active.

TWW Specific: Use Vicious Flask of Honor to boost your honor gain by 15%, it's cheap on the AH and persists through death! You can also use warbands to complete weekly quests on multiple characters and transfer honor to your main.
