From the PDF: Adventure module FI1, “Isle of the Fire Spirit,” is an adventure for three to five 5th-level characters that is played on Fireball Island! Each player should use one of the figures from the Fireball Island game to represent their character (at least while traveling on the island). If there are five party members, your group will need a copy of the Fireball Island: The Last Adventurer expansion to obtain the fifth figure.
