Fist (Level 48)

 is Ayla's third-upgrade for her Fist in, exclusive to the DS release of the game. Upgrading her critical hit rate from 25% to 30%, she receives this boost at level 48 and keeps it until level 72, where she receives another upgrade.

Since this upgrade is exclusive to the DS release, Ayla will not receive it in the original Chrono Trigger for the Super Nintendo Entertainment System. Instead, Ayla's fist upgrades to Iron Fist at level 72. As well, these weapons are simply upgrades to her combat skills and cannot thus be equipped to other party members, sold, or unequipped.
