Greetings adventurers!
To attract visitors to his remote northern port of Fang, the sinister Baron Sukumvit devised a deadly challenge for anyone daring-enough to accept. He ordered the construction of a massive labyrinth beneath the town hillside (from which there was only one exit) and filled the tunnels with mighty monsters and deadly traps. The dungeon was devised so that an extreme combination of brains and brawn would be required to survive.
When the Baron was satisfied that it was ready, he sent ten of his finest guards into the labyrinth, fully armed. They were never seen again.
Since then his "Trial Of Champions" has taken place each year and numerous adventurers have attempted "the walk" as it has commonly become known. No-one has ever emerged alive.
The chances of survival are almost zero, but the prize to anyone who can triumph is the immense sum of 10000 g.p.
This year you have decided to attempt the challenge, so pack your sword, provisions and potion-of-your-choice and head for Fang!

The difficulty level of this adventure is very nicely balanced. It starts fairly easily, but provides several tough battles towards the end. You will need a decent Skill score and reasonable Luck score if you are to triumph.
The real challenge is finding the correct route, as described below. You must find certain essential info & items (marked in bold type) and if you miss anything you cannot complete the final puzzle.

If you need to listen to a paragraph again, use the reload symbol. (lower-left)
If you wish to skip the narrative in a paragraph and go straight to the options, use the arrow symbol. (lower-right)

This interactive version of the gamebook has a few minor (optional) changes to the format.

The game offers a short-combat format, where you only fight each enemy for three attack rounds and then, if you have survived, you win automatically. I think that this option makes the game too easy, unless your Skill score is very low.
If you prefer to use the original combat rules, where you fight each enemy to the death, you can select this option just before your quest begins.
Selecting auto-attack off in the menu (cog symbol, top-right) allows you time to decide if you wish to take a luck test before the next attack round.

You still choose the traditional FF potion-of-your-choice at the start of the game, but in this version your potion contains two doses, not one. Again, i feel that this makes the game a little too easy, so if you prefer you can simply limit yourself to using your potion once.

You have the option to either roll your own stats and choose a potion, or to select one of three "ready-made adventurers" with predetermined stats and potion choice.

Choose the potion of fortune.
