Falling Between The Quacks

Interact with quackers on the platform that you enter the raid on. Give him a marker, when the trash is cleared the boss will spawn and quackers will be on the boss platform. Upon boss pull he will attack the boss, when he summons the adds in the rift quackers will be found in the rift only. Every player from the raid must interact with quackers to remove a corrupted feather. Once every player has done so he will escape the rift and attack the boss. At this point the boss can be killed normally.

When you enter the dreamrift, you will see [npc=254774] to the left. Interact with him, clear the trash, and go to the boss platform, Sargent Quackers will be there waiting for you. Give him a marker so he’s able to see and start the fight.

During the part where half the raid phases, Sargent Quackers will also phase and will start running around, all players that are phased need to interact with Sargent Quackers to count towards the achievement. He’s quite fast, but when one player manages to interact with him, he’ll stand still for a bit giving other players a chance to interact. You’ll know you interacted with him because you will see a feather circling around you. The next half of the raid needs to do the same during the next phasing.

Tip: Be sure to prioritize the adds first to avoid wasting too much time chasing Sargeant Quackers, you can always get him in the another phase.

Once all players interacted with Sargent Quackers, the achievement is met, continue the fight and defeat the boss.
