This feature is only available for Inheritance Gears and Orange Gears 1-star or above. Ranking up Inheritance Red Gears will cost the corresponding Craft Scroll, Craft Ore, Star Crystal, and the gear that will be inherited to. Legendary Orange Gears however will just require the specific Craft Scrolls and higher-tier Craft Ore. Some gears will require higher character level based on reborn times and level.
