List of Shin Megami Tensei: Strange Journey Forma

Forma are special materials peculiar to the Schwarzwelt. They can be used to develop equipment and extend the protagonist's Demonica's functionality. They are obtained from defeating enemies in battle and from searching the field in a given sector. There are 3 types of Forma: base, assist and rare.

Forma Types
Base Forma are Forma pieces intrinsic to each sector and come from the Sector itself, rather than having a specific demon produce them. Base Forma are used in the development of weapons, armor, accessories and items.

Assist Forma are the remains of defeated demons, and are essentially the spoils of battles. Specific demons produce specific types of Forma. Assist forma are combined with base forma to develop weapons, armor, accessories and items.

Rare Forma are, as implied, rarer Forma types that are used exclusively for the development of programs to augment the Demonica's capabilities in the field, from enhancing the demon-searching capabilities, to allowing more door-unlocking programs, or finding higher-quality Forma in the field, etcetera.

Forma Rarity
There are, as well, three types of Forma based on the rarity of the Forma; orange forma stands for A Type Forma, the most common and easiest to find; these can be found with no need of augmentation.

Silver forma are B Type Forma, a rarer type that requires the special Forma Search program enhanced with the Goetite Rare Forma found in Sector Eridanus. New types of Forma in earlier sectors are revealed with it.

Gold forma is C Type Forma, the rarest Forma type, which requires the ultimate augmentation to the Forma Search Program, brought about by the Hexagram Forma in Sector Fornax.
