Dragon Age: The Veilguard

If you head to the Necropolis after you’ve recruited Emmrich, you’ll be able to take on the side quest, “Restless Spirits,” where you have to rescue 4 wisps from around the central atrium of the Necropolis Halls.

Taking all 4 wisps to the door to the northwest in the atrium will open up the large doorway and the passageway beyond which leads to the Chamber of the Unforged. Once you open said door and make your way down the passage, after you've killed a few enemies, the side quest “Restless Spirits” will come to a close. However, if you walk up to the door further down the corridor, you’ll speak to a spirit and start the next side quest, “Pinnacle of its Kind.”

In “Pinnacle of its Kind,” you’ll have to head to the Arlathan Forest, Dock Town and the Hossberg Wetlands to kill a powerful spirit (and their back-up). Once you’ve defeated all 3 you can head back to the Chamber of the Unforged and gain access to the main arena for one more fight. This time you’re facing off against a level 40 high dragon called “The Formless One.”

The Formless One isn’t too difficult as long as you learn when to dodge and focus on weak points when they arise. In fact, we defeated it at level 30 and still had a couple of health potions left at the end. Just make sure you can trigger a few combos and you should be good (we used Bellara’s Enfeebling Shot and Taash’s Dragonfire Strike to do some serious damage).

Once you defeat the high dragon, ‘The Unbound’ achievement is all yours.
