This is video #102 in my playthrough of Final Fantasy IV for the PC. This is episode 20 of the third playthrough. I am playing on Hard mode. Final Fantasy IV [PC] Playlist: • Final Fantasy IV [PC] Playthrough Previously, the party explored more of the Lunar Subterrane. Among other things, they acquired the Dragon gear and the Crystal gear. They have reached the save room on floor B5. Now, they will gather the remaining treasures in the Lunar Subterrane. Lunar Subterrane: The party resumes in the save room on floor B5. They head south and exit to the northeast part of B5. Just to the northeast, they find another sealed weapon. When they examine it, they must fight the Dark Bahamut. The Dark Bahamut leads off with Megaflare, and it can use Megaflare as a counter to summons. So, summons are a bad idea. It counters Black Magic with Flare, which is much more manageable. It can put up Reflect, so it will help Rydia to have Piercing Magic. It can also counter physical attacks, so it is a good idea to put up Blink. At the end of the battle, Rosa reaches Level 67. Rydia reaches Level 67. The party obtains the Ragnarok. Cecil sticks with the Onion Sword. The party returns to the save room, where they rest at the save point. They take the northern teleporter to the western stairway on B5. Downstairs, they take the next teleporter to the western stairway on B6. They take the next teleporter to the southeast of the bottom level of B6. Cecil reaches Level 68. Edge reaches Level 67. On the middle level of B6, the party takes the eastern door to a hallway. In the northwest of the hallway, a chest contains a Minerva Bustier guarded by two Moonmaidens and a Dark Sage. Rosa and Rydia stick with their current equipment. The party takes the northeast stairway down to floor B7. There are three doors along the southern hallway on B7. Behind the middle door, the party finds another sealed weapon. When they examine it, the Plague Horror attacks! It puts Doom on the entire party and tries to speed them on their way to the grave with Haste. Fortunately, it is pretty easy to defeat in this version of the game, especially with good augments. And if Cecil or Kain has an Onion Shield, he is immune to Doom! At the end of the battle, Kain reaches Level 67. The party obtains the Holy Lance. Kain sticks with his Onion Sword. The eastern door leads to a room with two treasure chests. However, as the party steps into the room, the Lunasaur attacks. It likes to use Bad Breath, which sticks a bunch of nasty status ailments on unprotected party members. If Cecil has the Crystal gear, he is protected. The Onion Shield will also protect Kain or Cecil. The Lunasaur can counter by putting up Reflect, so if Rydia is going to use Black Magic, she should have Piercing Magic. Be glad the 3D version of the game only gives you one Lunasaur. At the end of the battle, Rosa reaches Level 68. Rydia reaches Level 68. The chests in the north of the room contain two Ribbons. Rosa and Rydia equip them. The western door in the southern hall on B7 leads to a save room. North of the save point, a chest contains a Cottage. The party rests and saves at the save point. Cecil reaches Level 69. Edge reaches Level 68. In the north of B7, the party takes a stairway down to B8. They're getting close to the end! This is the start of the Lunar Core area in other translations. Look out for dangerous enemies like Deathmasks, Red Dragons, and Behemoths. In the west of the middle level, a chest contains a Fuma Shuriken. In the southeast on the bottom level, the party finds the final sealed weapon pedestal. When they examine it, Ogopogo attacks. Ogopogo is essentially Dark Leviathan. Its Deluge attack can really hurt. It can also counter offensive magic with Blaze. It is probably best to stick with physical attacks. At the end of the battle, Kain reaches Level 68. The party obtains the Masamune. Edge equips this ninja sword. The party takes the southern stairway down to floor B9. In the northeast of the middle level, a chest contains an Elixir. Rosa reaches Level 69. Rydia reaches Level 69. In the southwest of the bottom level, a chest contains a Gold Hourglass. The party continues down to floor B10. Cecil reaches Level 70. Edge reaches Level 69. In the east of the middle level, a chest contains a Fuma Shuriken. In the west of the bottom level, a chest contains an Elixir. Kain reaches Level 69. Cecil equips Safe Travel to prevent additional encounters. The description is continued in the comments.
