Makluva Sucker

Armor made from fish scales. Soft, yet still able to effectively repel attacks.
Armor made from the blade-shaped scales and fins of Cephalos, the "Sand Wyvern," and from fish such as the Spring Night Carp. Because it grants the protection of water, many hunters say it makes them better at fishing. It can be upgraded by adding materials from Plesioth, the "Water Wyvern" and Cephalos's opposite.
