1. Fly to the west and enter R'Iyeh.
2. Go straight and get inside the temple.
3. After you entered, take the right path and continue to the next intersection. Turn right to get the Cthulhu's Sword, then head north. Follow the red fires and take the stairs.
4. Cross the bridge and enter the next temple. Follow the path and head west at the first intersection. Continue and turn right and the second intersection. Take the first path heading north and turn right. Cross the bridges and take the north path when you see the red fires.
5. Save your game and get on the bridge. You will meet the team of heroes and will have to defeat them.
6. The fight will be very short because your opponents are very easy. Just hit them once to kill them.
7. Continue on the bridge and take the stairs.
8. Take the left path and turn right at the next intersection. Continue and head south. Take the bridge on the north and follow the path. When near the three Cthulhu statues, head east and go upstairs.
9. Get inside the next building. Take the north path and then head west. Follow the path to the next intersection and head south. Follow the red fires and save your game before using the stairs.
10. Go on the top of R'Iyeh and meet the Cthulhu Golem.
11. The boss has 35000 HP. Start by making him insane and poison him. Use Rain of Fire of October to hurt him every turn. Berserk of Cthulhu, Multi-Strike of Sharpe, Smash of Ember or Lightning of October are powerful attack you can use against the boss. Keep one of your character for healing, such as Umi or Dacre.
12. After the fight, Azathoth will appear. Head north, save your game and confront the final boss. Have a team with a healer and three strong fighters.
13. Azathoth has 66666 HP. Like usual, make him insane, poison, Rain of Fire and Kraken of Cthulhu and Umi. This will deal great damage every turn. Azathoh uses attacks that targets several or all of your party members. Don't hesitate to use healing spells or potions even if you lose time. Cthulhu will deal great amount of damage with Berserk if the boss is insane. Be patient and defend yourself against the boss.
14. You have saved the world. Congratulations!
