Materials are items used in the player's development.

Tier 2 to 5 materials can be produced in the Workshop by using those of the preceding tier (e.g. an Orirock Cube costs 3 Orirock).

Upgrade

Upgrade materials, also known as elite materials or enhancement materials, are used for Operators' skill upgrades and Specialization training as well as their promotion and both unlocking and upgrading Operator Modules.

Many Main Theme and event operations have Tier 1 to 3 upgrade materials as their regular and extra drops, while some Main Theme operations have Tier 4 upgrade materials as special drops.

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

Tier 1 and 2 upgrade materials can be purchased with Credit in the Credit Store, available at random in each day.
Tier 3 upgrade materials can be purchased with Commendation Certificate at the second phase of the Commendations Store.
Certain Tier 4 upgrade materials can be purchased with Distinction Certificate at the Distinctions Store.
Tier 1 to 4 upgrade materials can be purchased with Headhunting Parametric Model in the Headhunting Parametric Model Store.
Tier 5 upgrade materials can only be produced in the Workshop.

Tier 5

Coagulating Gel, Incandescent Alloy, Incandescent Alloy Block, and Polymerized Gel are introduced alongside Episode 06.
Crystalline Circuit, Component, and Electronic Assembly are introduced alongside Episode 08.
Compound Cutting Fluid, Cutting Fluid Solution, Refined Solvent, and Semi-Synthetic Solvent are introduced alongside Episode 09.
Nucleic Crystal Sinter, Transmuted Salt, and Transmuted Salt Agglomerate are introduced alongside Episode 11.
Aggregate Cyclicene, Cyclicene Prefab, Fuscous Fiber, and Solidified Fiber Board are introduced alongside Episode 13.

Note: Aggregate Cyclicene, Coagulating Gel, Compound Cutting Fluid, Crystalline Component, Fuscous Fiber, Grindstone, Incandescent Alloy, Loxic Kohl, Manganese Ore, RMA70-12, Semi-Synthetic Solvent, and Transmuted Salt cannot be produced in the Workshop and must be farmed from operations.

Skill Summary

Skill Summaries are used for Operators' skill upgrades and Specialization training.

Aerial Threat operations are the most efficient place to farm Skill Summaries.

Promotion

Promotion materials are used for Operators' promotion.

Chips are used to promote 4★ and above Operators to Elite 1 and can be obtained from the first Fearless Protection, Fierce Attack, Solid Defense, and Unstoppable Charge operation.
Chip Packs are used to promote 4★ Operators to Elite 2 and produce Dualchips (see below), and can be obtained from completing the second Fearless Protection, Fierce Attack, Solid Defense, and Unstoppable Charge operation.
Dualchips are used to promote 5★ and 6★ Operators to Elite 2, and can only be produced in Factories by using the respective class' Chip Pack and Chip Catalyst which can be purchased in the Purchase Certificate Store.

Building

Building materials are needed to construct and upgrade RIIC facilities.

Resource Search operations are the most efficient place to farm Carbons, but Building Materials can only be produced in the Workshop by using Carbons.
