But upon closer inspection, he realized that out of the five Mysterious Grade items, only one was usable by him.

[Mysterious Grade · Tide Singing Robe]: Defense +35, Water and Fire Resistance +10, Toughness +12%, comes with the skill [Azure Sea Tide Song]

Azure Sea Tide Song: Allows free movement and attack in water for 30 minutes, cooldown time 12 hours.
