Libra ( ability ) Libra , also known as Scan , Peep , or Intel , is a recurring ability in the series . It is often a White Magic spell , but at other times is a separate command ability . It displays an enemy ' s stats and elemental strengths and weaknesses . In the later 3D installments one could rotate a scanned enemy around to see it from all sides . Depending on the game , some enemies are not affected by Libra , usually bosses or higher - level enemies . Libra should not be confused with Scan . Libra was translated as Scan in earlier games , but more recent translations have made the two abilities distinct . The key difference is that Libra is usually a spell while Scan is a command ability , and Scan occasionally has a more potent effect , such as working on all enemies at once or removing an enemy ' s status effects similar to Dispel .
