| To access the Subcommand, press right on the
left analog stick. This menu enables characters to change equipment
during battle, or attempt an escape from battle.
The Weapon and Armor commands enable a character to change
equipment during battle. If you are fighting a element creature,
use the Weapon command to equip a weapon that strikes with
the opposite element to inflick more damage. Similary, if
your character keeps getting put to sleep, then use the Armor
command to equip armor bearing the Slep Ward or Sleepproof
The Escape command allow one character to run from battle.
Keep in mind, however, that this option doesn't always work.
Also you cannot escape from boss fights. You can also use
Tidus's Flee ability to have your entire party escape from
enemies but not boss battles.
