While Hades 2 introduces several new characters with intriguing new boons, it's hard to argue against Circe being the most interesting of the bunch. While Narcissus, Echo, and the others all offer extremely helpful boons, for the most part, they are all relatively straightforward, providing upgrades that Hades regulars would not be surprised to find. Circe does offer her share of basic boons, but the best of her offerings affect Melino in ways most players never saw coming.
