Dengeki held a stream for Final Fantasy Explorers this morning, showing off a fair amount of gameplay as well as a few new classes. Dark Knights make a return, who like in previous Final Fantasy titles, can deal more damage by sacrificing their own health. Dragoons were also revealed to be available in the game.
In addition, a 'Trance' ability allows the player to temporarily transform into classic Final Fantasy characters, such as Cloud Strife. Doing this will also change the music to a track from that character's respective title.
Thanks Nintendo Everything for capturing the stream footage.
