Combining

The Combine function allows converting lower-grade items and monsters into higher-grade items and monsters. Combining always requires 5 of the starting item to create 1 item at the next higher grade.

The following items can be combined:
 * Insignia: 5 insignia of a given grade produce 1 insignia of the next higher grade. See Combining Insignia for more detail.
 * Some Materials, including:
 * Raw Iron
 * Crystal Ball Cores
 * Monster Spirits
 * Stardust
 * Monsters of C to S grades: 5 monsters of a given grade produces a variable number of fragments of a random monster of the next higher grade (possibly but not necessarily enough to complete a summon).
