Bon, je viens de commencer alors...
J´ai lu sur gamefaqs, dans un article sur le bestiaire:
IV. One Timers
There are a few monsters who can only be found in areas
that are only accessible for a short time in the game. Some
can be found later in the large bonus dungeon included in the
GBA version, the Lunar Ruins, however it is recommended you
pick them up immediately, if you are a completionist. =)
There are also two bosses that can be missed depending
on how you go about defeating them.
We´ll briefly discuss the two areas that can only be accessed
for a short time, and the two bosses that can be missed.
Monsters that are encountered in these locations but are not
listed as being missable can be found in the large post game
dungeon, the Lunar Ruins.
Ca voudrait dire qu´il y a un espoir¿
