How refinement is counted
Refined stats: Damage, Magic and Defense grow with refinement. Other stats stay at their base value.
Multiplier: +1 to +10 add 10% per level (+10 is ×2.0). +11 ×2.2, +12 ×2.5, +13 ×2.8, +14 ×3.2, +15 ×3.7.
Set: the Arch set of each class is compared with the Unique Legend set. The Full Set card has its own refinement, applied to all four pieces.
