How this card plays
The group circles a shifting center and sends radial shots. Read the moving gap, then make short dodges rather than following one enemy. The first warning introduces Ribbon Sweep. Later volleys alternate between that signature and the formation pattern. Survive three waves to earn a clean clear, or take one free assisted clear.
