You're here to test your courage, but what could the proof be?
What the hell? Is this some sort of early anti-cheating mechanism? There is absolutely no way to get here without the Crown without a Game Genie or some other form of cheating.
Step onto the throne to go to the next floor.
This floor is a maze. The pillars are teleporters. You can refer to the map for which ones to take, or follow the screen shots:
Mancats are the terror of this floor. Their FIR2 can be quite dangerous.
Sorcerers also make an appearance here. Always run from them, as they can kill with one hit.
Here we have the extremely useful Zeus Gauntlet, the first spell-casting item. Watch out, there'll be 2 MUDGols waiting there. Fortunately, this is another one of those linked chests, if you don't get it here, you can get it on the next floor.
And on to the next floor...
Watch out, when you go thru the door there'll be a Nitemare or 2 waiting for you.
This is, in my opinion, the most useful weapon in the game. It casts Heal when used as an item in battle. This makes things a lot easier.
These are great for your non-armor-wearing classes.
Oooh, an Ice Sword. These are pretty good.
Here's that linked chest. See? No MUDGols here.
Eww, a rat's tail. This is what you've been looking for?
One or two Zombie Dragons will be waiting in front of the exit. They aren't too hard if you make sure your HP is okay. As long as you have plenty of Fire and/or Harm spells you can keep fighting them to get experience and G.
You've got the Tail, take it back to the Cardia Islands so Bahamut can reward you.
If you're following my path you haven't been to the Ice Cave yet, so get going.
