Guild Wars 2

So I recently hit lvl 80 for the first time in GW2 as a Warrior, and heard/read that its a good thing to start as early on as you can with getting ascended stuff, so i went and looked online on qtfy for a warrior build I liked and would love to have eventually found this one ( http://prntscr.com/f2oiqv ), but I kinda got confused at the trinket parts as i do not really know where/how to get them, i am pretty sure on how to get the weapons and armor, by crafting, but am not sure about the trinkets etc. could somebody help me with that part? like how do i get the trinkets, rings etc. do i also craft them or buy them from a special vendor?

The link to the site: http://qtfy.eu/build/warrior (build i want to have is Condition PS Warrior)
If somebody could please help me out with this I would be very grateful!
Thanks in advanced

The wiki provides info about all the ascended trinket vendors. https://wiki.guildwars2.com/wiki/Ascended_trinket

Super easy to get ascended trinkets. Just go farming in Ember Bay, Bloodstone Fen, any living story map. Each newer living story map drops a unique item from material nodes like Petrified Wood in Ember Bay. The petrified wood can be traded for ascended trinkets

One PRO tip !

You cannot wear 2 of the same trinkets with the same name.
