Phantasy Star series
Phantasy Star II
In Phantasy Star II, saner costs 6 TP to cast. It increases the entire party's agility by 10 for the duration of the battle. Repeated uses of saner stack.
Amy is the only player character who can use saner. She learns saner at level 25.
Phantasy Star IV
In Phantasy Star IV: The End of the Millennium, saner costs 6 TP to cast. It increases the entire party's agility by an amount equal to the user's mental stat. This increase lasts until the battle ends, or replaced by another agility modifying effect (such as doran), or the party member wakes up from sleeping. Saner does not improve the party's defense stat, but does make them more likely to dodge hits and to act before the enemies each round.
