The Mystic Hardfang is a Rarity-8 Monster Material in Monster Hunter Rise: Sunbreak and is used to forge and upgrade a variety of Master Rank weapons and armor. Specifically, this Monster Material is required for crafting the Hard Satiated Jewel 4, Hard Wall Run Jewel 4, Die Walküre+, Khezu Coil X, Khezu Vambraces X, Khezu Greaves X, and Squire's Braces. Additionally, players need Mystic Hardfangs for upgrading weapons in Monster Hunter Rise: Sunbreak, including the Die Walküre+, Painful Razor+, and Khezu Flute+.
As the names of some of the gear pieces above suggest, the Mystic Hardfang is a Monster Material acquired from Master Rank Flying Wyvern known as Khezu. Appearing in previous Monster Hunter titles, Khezu is a pale, amphibian-like Large Monster with a rubbery and fatty hide. More notably, this Wyvern has no eyes and uses its superb sense of smell to track down its prey. Khezu's Element is Thunder and is capable of inflicting Thunderblight, Paralysis, and Stuns. Additionally, this blind Flying Wyvern possesses a tail with a specialized orifice that allows it to stick to the ceiling of caves within its habitat.
