How to beat Antlion - Final Fantasy Resonance

Have everyone level 15. Don't use physical attacks at all. Give everyone physical counter. Rain - WOL, Fina - White Mage, Laswell - Terra. Have rain keep up provoke and protect then cover all when it flashes red. Have Fina use Cura on party. Use ethers and pass turn to Laswell. Laswell use focus magic then magic boost - Watera over and over. Stagger then hit limit breaks. Works on expert.
