Walkthrough

- Starting out. Talk to him again after the cutscene. Travel to the Quetzacalli Gorge (There is a Quetzal landing site that is automatically unlocked). Talk to the bartender in the south-west pub and ask to rent the room for 30 coins.
- The First Trial. Use the key to open the south-eastern gate, open the chest to receive a book and scrap of paper Open the south-western chest with a keyword. The solution is different for each player. The solution can be found by connecting the first letter of each highlighted word in the book
- The Second Trial. Speak to Forebearer Janus again to start the next trial.
- The Third Trial. You must question each member of the cult to work out who the traitor is. Choose the person who mentions anything about Mictl as this is not part of the Emissaries' beliefs. Once you question each one, you'll be given the option to accuse them while talking to them. If none of the members are the traitor you may need to exit and re-enter the floor.
- The Final Trial. Fight Prince Itzla. Pray melee against his basic attacks. He has two special attacks, both of which he warns you about. The sword swipe turns off any protection prayers, but you can turn them straight back on. The other is an AOE attack, once he warns you he is going to do it, run behind him immediately to dodge.
- Ice Dungeon. Mine the rocks. Run past the Frost Nagua and the spikes and pull the first lever. Climb-Down the Ledge, run past the frost crabs while avoiding the traps.
- Statue Puzzle. Level 104 Frost Nagua will continue to spawn and attack you while searching. Protect from Magic will negate the damage from their regular attacks. Fix the broken statues in the western area with the corresponding coloured icons. Inspect the four markings in the four corners of the area. The first word describes the order in which to activate the four statues to open the frozen door.
- Final Boss. Pray magic Step away from the spikes Avoid standing on the ice pools
