Apart from the main storyline, FF XIII's side-quests take the form of missions that you take from Cie Corpse obelisks. These missions are spread throughout the lower city of Gran Pulse where you're tasked to kill specific monsters. Loot from these monsters, in addition to rewards from completing the quests is an invaluable source to upgrade your weapons to their ultimate forms. It's also possible to replay these missions over and over should you like the grinding aspect of RPGs.
