Now you only mission is to beat the 7 Jinjus on the map. Here I will describe the attributes for each of them (It is not a recommanded order). Also, before you enter each of these stages, you'll meet two cats: one selling weapons and one selling armors. As you beat more Jinjus, their weapons/armors becomes better but more expensive. Unless you're very wealthy, I don't recommand you to buy them all. Instead, collect "Weapon/Amour Seed" by opening treasure boxes after you finish one scene of fighting and plant it in the inn. Those stuffs are better - and they cost you nothing! Now here's the Jinjus:
Monster of Fire: Remember the forbidden passage in the Mountain of Flame? That's where the monster is. Fly to the Mountain of Flame and go through that passage. Since the enemies inside are quite tough, so do quit your mission if you don't feel good (it's another way to raise your level up to 38 - the second class change). The Jinju there is afraid of Water magic, so do cast that kind of magic (Hawkeye and Angela can cast such magic, while Charlotte and Duran can attach that magic onto their weapons).
Monster of Water: It's just near where you found the Spirit of Ice. Enter the cave where the Mana Stone was located and go to the nearly entrance. Also, the enemies inside are quite tough (especially the "kung-fu" dragons). The Jinju there is an ice dragon. Use Fire magic to beat it - it's easier.
Monster of Wind: It's at the end of the Corridor of Wind (the enemies inside are less tough, so it's suitable for beginners), where you found the Spirit of Wind. Land on Rolant and go to the Corridor of Wind. When you reach the end of the Corridor, Fairy says, "The Jinju is over the sky. Let's call Flamie and beat it!" You call Flamie, and it brings you up on the sky. The Jinju is amother flying dragon. Use Earth Magic to beat it. Since its HP level is quite high, so be patient and check out your HP. Monster of Earth: It's near the Crack of Earth. Landing there require patience, since you may land on a wrong place very often. If you reach a cliff while landing, that's it! Go from there and you'll reach the Forsena Pastoral again (believe me, you're not in the wrong way). After passing the two cats, you'll reach the Jewel Mountain. The passage is quite long and the enemies are tough, but it has 2 golden Mana Statues inside (no pain no gain). The Jinju inside is a spider-like robot. Its attack power is quite great, but its HP level is lower. Use Wind Magic often, and you'll make it.
Monster of Wood: It's NE to the Lampflower Forest. The forest you land is the Wander Forest. There's not much difficulty inside. The Jinju inside is a giant pumpkin. Its attack power is great and its HP level is high. It's quite hard to deal with it. Be patient again and I think you'll make it again.
Monster of Light: It's east to Wendel, inside the abondoned Temple of Light. There's two locks inside. To open them, cast the Spirit of Darkness on one of the locks and the Spirit of Light on another (you can see the clues inside the Temple). The Jinju inside is a giant spider. Since only Angela (irrespective of class) and Charlotte (only in Dark class) can cast Dark magic, it will be a tough battle if you don't have either. The Jinju's magic power is great, but its HP level is low. Watch out your HP and you'll beat it with ease.
Monster of Moon (believe me, it's the toughest one): It's inside the Moon Tower, where you beat Rugar and get the Spirit of Moon. In the past, all of the doors inside are locked. Now they're not. The enemies inside are very tough (especially the werewolves), so do refresh yourself under the Mana Statue (there's 2 inside - 1 just near the top of the tower). The Jinju is a dragon-like creature (it can't fly like Flamie). Its attack power is very large, especially Kamehameha (it's not the real name, but it does look like Gokuh's waza. Courtesy of Akira Toriyama) which reduces your maximum HP for a while. Be careful of your HP and be patient.
After beating all the above Jinjus, you ask Fairy, "How can we find the last one?"
"Let's go to Pedan inside the Mysterious Jungle. The people inside that city have seen Goddess Mana saving the world (similar to the mysterious town in FF5). They may know where the Monster of Darkness is."
So you ride on Flamie. The location is highlighted on the map.
That's all this time, folks
