Collectibles are items in Xenoblade Chronicles X. They can be found on the ground scattered around Mira, and they appear as blue crystals on the ground, water, and in the skies of every continent. Collectibles can be sold, used in missions, item creation (augments, weapons, armor, Skells), and to fill the Collectopedia to get rewards. Collectible appearance is based on continent, area, time of day, and rarity.
