Frosilka was the head of the Royal Guard while Thetys was the Queen of the Water Realms. Stronger than Thetys herself and extremely loyal to her, Frosilka was excellent at her job, but when Thalassa came back, she couldn’t stand serving another queen, so she quit the guard. Now she’s devoted to helping Thetys seize power from her mother!

Frosilka is a unique Support monster that protects his team against control skills, gives Stamina and heals. She's the first monster with the Dodge Area trait, which makes her immune to area attacks: She can only be hit by single-target ones! But she also has damage-dealing moves, Shock skills, and a Thunder attack that causes lots of trouble to other Water monsters.
