Secret Sword is the signature Fighting-typemove of Keldeo. This move can be learned by via tutoring when the rest of the Swords of Justice are also in the player's party and the player visits an old man in the Moor of Icirrus. However, it is weaker than its counterpart, Sacred Sword. It also allows Keldeo to switch to Resolute Form when learned. This move was introduced in Generation V.
Secret Sword inflicts damage. Although classified as a Special move, this move calculates damage using the user's Special Attack and the opponent's Defense stat.
