FGO Arjuna Alter Boss Fight F2p, Budget Team

Leonidas HEAVILY carried this run. The fight is not that hard until the last bar where AA will whoop out his pierce invul and that's a BIG problem for f2p teams since they don't have Castoria. So Asclepius becomes your best friend in this comp (that's ironic). I'm not sure whether non-grailed Cú would work or not (i highly recommend grailling him) but since you've already been to LB4 that means you must have had quite a bit of resources so....yeah go and upgrade your Cú.
