Upgrade materials, also known as elite materials or enhancement materials, are needed in Operators' skill upgrades and promotions.

Many main and sub operations have T1 to T3 upgrade materials as their regular and extra drops, while some have T4 upgrade materials as special drops. The materials' rough drop rates are listed below:

  • Guaranteed: 100.0% or higher (if higher, more than one copy of the material may be dropped)
  • Common: 70.0% ~ 99.9%
  • Uncommon: 40.0% ~ 69.9%
  • Rare: 10.0% ~ 39.9%
  • Very Rare: 9.9% or below

The drop rates above, however, are often inconsistent in most operations; refer to each specific material for the exact rates.

Other than from operation drops, upgrade materials can be obtained through the following:
