Tigrex Leggings S

Made of Tigrex materials. Like the tyrant, it exudes earth pulverizing power.
By using rare materials in abundance, such as Tigrex claws that crush even rock and scales that repel any force, the Rex series was successfully strengthened. It gained even more toughness, but on rare occasions the wearer takes deeper wounds than usual. Among hunters it is whispered, as if it were true, that the spirit of the slain "Roaring Wyvern" draws evil spirits to the wearer.
