Siren is the first Guardian Force that it is easy to miss during a regular playthrough. Siren does not have a very strong attack but her attack does have a chance to Silence the enemy. Even with that potential, Siren is one of the weaker Guardian Forces available. Some of the abilities that she can learn, such as St-Atk-J and St-Def-J, prove very useful throughout the game.
Attack Name: Silent Voice
Attack Effect: Non-elemental attack (low damage), Silence effect
You have to Draw Siren during the battle against Elvoret at the top of the communication tower in Dollet (during the SeeD Exam).
Alternatively, if you missed this opportunity, you can draw it from the first sub-boss in Ultimecia’s Castle, Tri-Point.
