This battle begins with a fight against 26 Numidias enemies which are small, easy to defeat bat-like creatures. You should have your team focus on Area of Effect (AoE) attacks to bring them down as quickly as possible. Assuming you are controlling your 
Commandos, choose either your 
Ruinga or 
Blitz attacks.
The smaller Numidias can pump out a fairly high amount of damage, so consider swapping between Decimation and Diversity paradigms for healing and to slowly buff up your party members in preparation for the actual battle against Syphax which occurs after the 26 Numidias has been defeated.
The battle against Syphax does not require any advanced strategies. Just be prepared for it to keep summoning more Numidias to join the battle with “Grave Summons” which means you should focus your attacks on Syphax to end the battle quickly before things get out of control.
Make sure you grab both of the two Treasure Spheres before leaving the area. One of them contains four 
Perfect Conductors while the second contains two Particle Accelerators. Completing this Cie’th Stone’s Mission has removed the nearby Cie’th Paling allowing you access into the Haerii Archaeopolis, which is where the next Mission can be found.
