Four new espers are in Final Fantasy VI Advance: Leviathan, Gilgamesh, Cactuar, and Diabolos. Two new areas include the Dragons' Den dungeon, which includes the Kaiser Dragon, a monster coded but not included in the original, and a Soul Shrine, a place where the player can fight monsters continuously. Three new spells also appear, and several bugs from the original are fixed. In addition, similarly to the other handheld Final Fantasy re-releases, a bestiary and a music player are included. Even in the Japanese version, the music player is in English and uses the American names, e.g. Strago over Stragus. The package features new artwork by series veteran and original character and image designer Yoshitaka Amano.
