Just north where you reappear.

Enter the top room (D), make a quick save, review your equipment before the boss fight.

This guy absorbs fire but is weak to ice, so "Ice Bow" and "Blizzard" are very effective against him.
Take the stairs (E) to the next floor.
Note: you'll take damage when stepping on the ice spikes.

- C-169: Ice Brand - Chest in the east path.
Enter the room, make a quick save, and prepare for a boss fight:
Boss: Ice Gigas
This guy absorbs ice but is weak to fire attack, so "Fire" magic and any weapons with fire element like "Flame Lance" and "Flame Sword" are perfect to kill this boss.
Take the exit (G) to 6F.
- C-170: Elixir - Top-right corner.
- C-171: Wizard's Staff - Bottom-left near the door.

Take the exit (K).

Go straight north and talk to Minwu. Then enter the crystal chamber and examine all the 5 crystals.
Note: there is ONLY one "Ultima Tome", so you have to carefully decide which character you want to give it to. Ultima's power is based on all your stats (stats, magic levels, weapon levels, etc.), the higher they are, the more powerful "Ultima" is.
Step on the portal to warp out of the tower.
Leveling Up (Optional)
Since you just got 2 new powerful spells "Ultima" and "Flare", I highly recommend you start leveling these magic spells up as much as possible.
