Kill them first as they are the weakest among other Quaras but deal a lot of damage with magical attacks. Since they're slow, shooters won't need much space to run.
Knights: Try to avoid other quaras and just melee it. Exori if you are surrounded by 3 or more quaras. Mages: You can take it down pretty quickly with energy strike and HMMs, but be ready to cast a healing spell.
Paladins: Attack from distance or use shield and throwing weapon.
