As one of the four elemental gods of the island. Flint has been tasked with protecting the lava that powers the core of the island. Living in a volcano for several millennia, he has nothing else to do except watch lava, do sit-ups, and style his heat-resistant hair. Wanting to set the world on fire with both his looks and actual fire, he is looking to escape.
Each mastery level adds another card to the cardpool for defeating Flint. Each of the bronze, silver, and gold mastery levels unlocks a new card, while it takes all three diamond and onyx levels to unlock a single card.
