The Dragon Scales are Red Dragon Scale, Blue Dragon Scale, Green Dragon Scale, White Dragon Scale, and Black Dragon Scale.
They are fairly rare uncapping materials, mostly because there is a single tier of them, so there are no Treasure shop options to trade for them.
Dragon scales are primarily used to uncap characters. They are needed for intermediate stars on SR and SSR characters.
