The main story of Spell Saga is told in three acts, with each act split into a deck of cards. The story involves The Last Minstrel, who is searching the world for answers about how the world ended. Deck One ~ The Highlands serves as the Base Set of the game. The rest of the story is told through a limited number of expansions. These include Deck Two ~ The Forest & Deck Three ~ The Caves.

Advanced players will find a challenge with Deck 0 ~ The Prelude ~ (an optional standalone beginning to the game)
