How to Complete Meeting the Quota
The objective is to gather all of the licra ore. To do this, you have to check all of the sparkles in the playing field.
The enemies are a bunch of undead monsters: Ghosts, Zombies, and a Ghoul. If you kill these, they will turn into graves on the field, and those graves will turn back into the monsters after a few turns. However, you can use moves like Exorcise or Burial to permanently remove those graves from the playing field. Since these enemies are weak to Holy, a Paladin's abilities can be helpful. However, since the objective is to just collect all of the sparkles, you can ignore the enemies if you prefer.
