There are several new achievements on the Dragonflight Patch 10.1 PTR, covering quests, exploration, reputation, collections, and new dragon races!
Several of these achievemensts are what you’d expect from a new Season and raid tier, such as Keystone and PvP achievements, though there are also a handful of fun ones mixed in. Elemental Conjuror seems to be a new kind of world PvP achievement, while Pyramid Scheme awards one of the recently found new titles!
