This rare material, found within the Granblue Fantasy universe, is a key resource utilized in character and weapon progression. Specifically, it serves as a crucial component in unlocking character skills, enhancing weapon proficiency, and undertaking certain character-specific quests. For example, acquiring a sufficient quantity is often a prerequisite for unlocking the final uncap of a powerful SSR character, significantly boosting their combat effectiveness.
Its importance stems from its relative scarcity and the significant power gains associated with its use. Acquiring it typically requires engagement with specific in-game content, such as daily missions, limited-time events, and high-level raids. Originally, the acquisition rate was lower, leading to a greater emphasis on efficient resource management. Over time, adjustments to drop rates and the introduction of new acquisition methods have altered its accessibility, affecting player strategies.
