Most Items provide in-battle support effects. It is highly
recommended that you keep ample stock of them as they are
important before you get your first healing Espers, where
you can start to learn Magic. Almost all items can be bought
from item shops. General items typically have recovery properties,
which could restore either the character's HP or MP values;
fix status ailments such as poison, imp or blind. Other items
include offensive items, which can be used to attack enemies
in battle.
