■ Example of SP obtained
When a player has purchased the Castle Design Customization Support Pack (5x), the Hero they're battling with is a Legendary Hero (2x), and they are playing Forging Bonds (2x):
3x5x2x2 = 60 SP
Note: There are circumstances where less SP is obtained. For example, when the foe's level is low and there is a significant difference between the Hero's level and the foe's.
