HCBailly plays Final Fantasy IV (Super Famicom) - Part 65 of 70

The optional boss rush continues with dinosaurs and...the Masamune. Nice.

Subterranean Valley Map (by FlyingArmor)

Equip Rosa with the Sage Staff and Edge with the Flame Claw before going into the room with the two chest. You'll fight two Lunasaurus. Have Kain Jump the one in the back, and have Cecil and Edge wail on the one in the front. Rosa can attack the one in the back with Artemis Arrows if you so choose, but she'll be healing more often. Have Rydia summon Bahamut to hit both Lunasaurus enemies with Mega Flare. The Lunasaurus will be attacking with Flame repeatedly, but if you can keep everyone's HP high, you should be good to go.

Beating the two Lunasaurus will give you access to two Ribbons. Give one to Rosa and another to Edge; Rydia will still need her Gold Band and Rosa and Edge will need the defense.

In this game, stat gains are fixed up until Level 70; past 70, they will be random and can go either up or down. So be careful.

When you approach the Masamune, you'll face Tidarithian, which will hit you with Big Tsunami and Flare. Have Rydia use Sylph and Rosa use Cure 4, and have Kain use Jump on every turn. Have Cecil and Edge attack normally. If you need to, throw a Hell Wind Shuriken. When you beat Tidarithian, the Masamune will be yours. It's the best sword in the game for Edge, so give it to him. It can also cast Fast when used as an item and increases Agility by three.
