Medals were attack-type equipment. Upgrading one from mid-grade to high-grade National Weapon level would greatly increase Yan Hua Yi Leng's damage output, while also raising attributes such as her movement speed. This was precisely what she lacked to complete the sixth stage of the Hell Trial.

Otherwise, she would have to use another Combination Equipment Awakened Skill. Without the effects of a Combination Equipment Awakened Skill, Yan Hua Yi Leng's movement speed would definitely be inferior to an Ancient Demon God-level boss's.
