Rize is a pretty good fill in for this GQ. Lin Leader/Sub, with Rize using any combination of Sphere+Status Null, or any dual damage sphere(Lexida+Fallacy/Heresy) also works quite well. Got me through Tilith/Lugina route. Of note, using Rize as your leader makes it very pot intensive due to the status effects Seria will endure.
