Fighting with Style: Hidden

This achievement is only earnable after you have first unlocked your hidden artifact appearance. All three remaining color variations are tied to progress you make after that prerequisite is met.

Complete 200 World Quests with your hidden artifact appearance selected. You do not need to physically equip the hidden appearance weapon — transmogging your weapon to another look still counts toward this total.

Complete 100 Legion dungeons on Normal, Heroic, Mythic, or Mythic+ difficulty. Return to Karazhan does not appear to contribute to this count, so focus on the original Legion dungeon pool. For fast farming, Darkheart Thicket on Normal can be completed in around 3 minutes at high gear levels: mount up at the entrance, ride the fastest path to the first boss area, go around the boss's wall to the right, and look for a green rock in a bush in the green area — most mobs chasing you will snap to that location. Kill everything chasing you in roughly 20–30 seconds, then reset.

Kill 1000 players through any PvP method, including Arenas, Battlegrounds, Open World PvP, or the Dalaran Underbelly, with your hidden artifact appearance selected or transmogged over.
