Shining Soul is an action RPG by Atlus. It is the first Shining game to not be produced by Camelot Software Planning, and thus is not considered canon in the Shining universe. However, the game serves as an internal homage to much of the Shining series. All of the bosses are major villains from a previous Shining game.
The author manipulates randomly-placed monuments to appear, increasing attack power as much as eight-fold during the run. Additionally, hundreds of critical attacks had to be painstakingly manipulated to allow for enemies to die in a single hit.
