It is an achievement in the "Explorer" category with the following description: Legendary CollectorSoulbind 5 unique Legendary items.Owner of some of the rarest items in Tyria. I used to have 3 pieces of legendary equipment: Shining Blade (sword), Exordium (greatsword), and The Ascension (back item.) The progress of the achievement shows that I have collected "3 Unique Legendary Items." Today, I finished the new legendary trinket Vision, but the achievement progress remains the same instead of showing I have collected 4 legendary items. Therefore, I am wondering if only the legendary weapons and back items are counted towards this achievement, but not the legendary trinkets?
