Guild Wars 2

how do I get Ascended Armor recipes, I check the wiki to find out how to acquire a recipe but there is nothing added there, I check there Black lion Trading post but there are only 3 pieces, not really the specific stats that I want, most of them are Ventari and keeper recipes, I was looking for Angchu recipe.

Talk to the master crafter for the crafting specialty you are using.

Depending on which stat combination you want, you need to buy them off the TP or for most of the stats combos from your crafting trainer.

For example:

→ QUOTE: Players will need to purchase a Recipe: Ascended Insignia and use it to acquire the recipe for the prefix they want. Players also need to purchase an ascended armor recipe for the appropriate piece of armor; a heavy helm requires a Recipe: Ascended Heavy Helm for example END QUOTE

and

Careful, the prefix of the armor recipe and the insignia recipe have to match.

As above poster stated, they are sold by the crafting vendor, they also cost laurels and gold(5 laurels and 3g) per piece.
