Character Ascension Materials are materials that can be used for ascending Characters once they have reached their current maximum level. Most of these materials are grouped by their element. All characters will require character ascension materials of the same element they use - the only exception is the Traveler, which uses an exclusive set of materials.
See Character Ascensions for details on when characters can be ascended. Check each character's page to see which materials are required for their ascensions, or check each materials page to see which characters use that material for ascensions.
