You Got the Beat

I have made a weak aura helper that makes it easier to do this, especialy if you are planing to fast spam it just for achievement.

While the oponent is performing his dance moves, click the icons you see on the center of the screen.
When its your turn to perform. spam the center button that appears and that will execute the sequence you inputed.

edit:
Weak aura updated for Dragonflight ui changes.
