Grandmaster blacksmiths can now craft a Masterwork Catalyst—a special item that upgrades normal magical gear (weapons, armor, and instruments) to exceptional quality. Required ingredients drop in small quantities from certain monsters, with higher-difficulty foes increasing your odds.

Gather the materials, unleash the catalyst, and elevate your equipment to new heights!
