How to craft and convert materials — a key system for upgrading characters, skills, weapons, and uniparts.
Material Synthesis lets you turn extra or lower-rarity materials into rarer ones needed for upgrades. It's an essential system for upgrading Weapons, Uniparts, and Character Skills — especially once farming becomes harder at higher levels.
Exchange materials of the same rarity for a different material of the same rarity. Useful when you have excess of one type but need another specific material.
Consume specific lower-rarity materials to craft one of a higher rarity. Essential for obtaining rare upgrade materials when farming isn't giving you what you need.
Items that are locked or unavailable due to missing materials appear grayed out. Make sure you have the required Spec-Ops Rank and materials before attempting synthesis.
Unimaterials come in three colors, each used to craft different Unipart rarities. You can upgrade them through synthesis.
| Color | Used For | How to Get Higher Rarity |
|---|---|---|
| Green | Craft ★3 Uniparts | Farm from Training missions |
| Blue | Craft ★3 and ★4 Uniparts | Synthesize multiple Green Unimaterials |
| Purple | Craft ★4 and ★5 Uniparts | Synthesize multiple Blue Unimaterials |
| Gold | Craft ★5 Uniparts | Synthesize multiple Purple Unimaterials, or exchange Encounter Stones in the Shop |
