Sword & Sorcery: Ancient Chronicles – Challenge Set

The Ancient Chronicles Challenge Set is a collection of all the "rank and file" enemies (green and blue) included in Ancient Chronicles in a variant rank, allowing players to modify the game difficulty and the overall game experience by combining the Ancient Chronicles Core Set enemies with these new enemies.
