there are simple tactics: usually you can fight her with a water parasoul who will absolutely need to finish the fight with a precision hit
other is Windswept Filia coz infinite Precision hits
If you got her now or before: Blue Streak Filia
or the last resort is using a tanky water fighter to get rid of her and **** it
