First, to enter the tower: Fly over the tower in the Falcon, and attempt
to land on top of it. The character selection screen should appear after
this, and you will be asked to divide your party into three groups. The
group to the left of the screen will be referred to as "Group #1" from
here on after, the middle group will be "Group #2," and the right group
will be "Group #3".
When selecting characters to go into these groups: Make sure you assess
each and every party's strengths and weaknesses before you go. Group #1
should be your overall weakest party, Group #3 should be your strongest,
and Group #2 should be somewhere in between the others.
Group #1 will have the easiest path through the tower. There are no
bosses to fight on the initial road through Kefka's Tower. After a
while, Group #1 will run into a locked door in a room where the two
other groups enter from the left and right sides of the room. The other
two groups can step on switches to open this door up. (This room and the
next room will be referred to as the "Convergence Rooms".) In the next
room, Group #1 can either move left or right. If Group #1 moves to the
left, they will have to fight the Doom Magi. If they move to the right,
they will have to fight the Goddess Magi.
(Hint: You might want to put Strago in Group #1. Doom is one of the only
monsters who can teach Strago the Force Field lore, and Goddess is one
of the only monsters who can teach Strago the Quasar lore. Either one of
these should be beneficial to Strago in the final battles.)
Group #2 should also have an easy trip through the tower. There is one
optional boss they may fight - Atma - if you want a Save Point. In the
Rooms of Convergence, the bosses Group #2 will have to fight depends on
where Group #1 went: If Group #1 moved to the left, Group #2 will have
to fight the Goddess Magi. If Group #1 moved to the right, Group #2 will
have to fight Guardian and the Poltergeist Magi.
Group #3 has the longest and most difficult path ahead of them. Along
the path, they will be attacked by one boss. (Remember Baigan from FF
IV? If so, this boss will be somewhat familiar to you.) In the Rooms of
Convergence, the bosses Group #3 will have to fight depends on where
Group #1 went: If Group #1 went to the left, Group #3 will have to fight
Guardian and the Poltergeist Magi. If Group #1 went to the right, Group
#3 will have to fight the Doom Magi.
Groups #2 and 3 will also run into two dragons just before they reach
the Convergence Rooms.
In the Convergence Rooms, it is **highly** recommended that Group #1
moves to the left. This will put Group #2 on the right, and Group #3
straight up the center. The center bosses - Guardian and the Poltergeist
Magi - are also the most difficult, and should only be attempted by
After the Magi are defeated, have each group move beyond them and stand
on the three switches. All three parties will now be teleported to
Kefka's room. After you choose your order for the upcoming battle, the
party will have to fight resurrections of all three Magi for a while
before fighting Kefka. Doom comes first, then Poltergeist, and then
Goddess. Once they are all killed, the party will then fight Kefka...
