Upgrade materials, also known as elite materials or enhancement materials, are needed in Operators' skill upgrades and promotions.
Many Main Theme and event operations have T1 to T3 upgrade materials as their regular and extra drops, while some Main Theme operations have T4 upgrade materials as special drops.
Other than from operation drops, upgrade materials can be obtained through the following:
- T1 and T2 upgrade materials can be purchased with
Credit in the Credit Store, available at random in each day. - T3 upgrade materials can be purchased with
Commendation Certificate at the second phase of the Commendations Store. - Certain T4 upgrade materials can be purchased with
Distinction Certificate at the Distinctions Store. - T1 to T4 upgrade materials can be purchased with
Headhunting Parametric Model in the Headhunting Parametric Model Store. - The Workshop can produce T2 or higher upgrade materials, costing lower-tier upgrade materials (e.g. T2 materials cost T1 materials, etc.), and is the only way to obtain T5 upgrade materials.
