Glory of the Dragonflight Hero

In Algeth'ar Academy on Mythic difficulty, defeat Vexamus without any player absorbing Arcane Orbs. Kite the boss around the room and avoid standing behind him, letting the orbs drift toward the boss on their own while the group sidesteps them.

Before engaging the Overgrown Ancient in Algeth'ar Academy on Mythic difficulty, every party member must click a Duckling from the pool behind the boss to place one on their head, then defeat the boss with all five ducklings still active. The ducklings apply a 65% movement speed reduction, but with current gear levels this is manageable.

In The Nokhud Offensive on Mythic difficulty, defeat the Raging Tempest after having all 5 Lightning Strikes hit a single player simultaneously and then killing the spawned Storm Elemental. Have the tank stand under the boss during Lightning Strike while all other players spread away, so all 5 strikes land on the tank, triggering the add spawn.

In The Nokhud Offensive on Mythic difficulty, three separate players must each retrieve one of the three weapons — the Spear of Tolui, the War Axe of Berke, and the Bow of Sartaq — from the caves around the boss arena before defeating Teera and Maruuk. Because each player can only hold one weapon, this achievement requires a minimum of 3 players.

In The Azure Vault on Mythic difficulty, defeat Umbrelskul without any player being hit by a polymorph trap or completing a Shriek cast. Avoid all Whelps that have a visible ring around them throughout the dungeon, as stepping inside those rings or attacking the Whelps triggers Shriek, which fails the achievement.
