Fatebot with Agil, Zekken, and Patrol Plugins keeps you killing, repaired, and wont stand in shit, make sure you blacklist any fates that will get you or your raptor chicken killed and go to town. Previous to Kagami's post of the 15-50 profile I would quest my chars to obtaining their choco's hit up the companion quest and make sure that they were leveling them through each of their combat classes.
