Okay, this is a great game. I mean it. It's possibly the best rpg I've ever played. After about 60 total hours of gameplay, I have managed to mentally note many interesting facts. I might not finish this little mini faq tonight, but It'll get done soon. To start off, most of the side quests and valuble items you can find.

Crown of the King Ghost
After you re-unite with Zola in the Great Desert and get the mechat, go to the cave in the Exile Forest(near Alumaru Village), and go straight to the deepest area. You will find a Poison Hydrattler, but don't worry, you should be fine if you're at a decent level(I killed it in a few attacks). Unlike the normal Hydrattler, you don't have to defeat the four heads, just pound away until it's dead. After defeating it, enter the small alcove it was gaurding and you'll find two chests, one protected by a black barrier, and one by a red barrier(more on the barrier devices later). The black barrier chest contains a mechat part and the red barrier chest contains the Epistle of the King Ghost, which is basically a letter he wrote before he died. After acquiring it, warp to the Forest of the Dead and there should be a green barrier somewhere blocking off a small area of the forest. Deactivate the barrier and enter to find a transformation chest that requires the Epistle of the King Ghost. Put it in, and in return you will get the Crown of the King Ghost, which doubles the money you get by winning battles.

Deafeating the Golden Poo Snake
After re-uniting with Zola, fly to an island called Southern Deserted Island. This is the only place in the game you will find the Gold Poo Snake. However, it flees all the time and is at level 40 with high agility, so it usually goes first. However, I have found that you can kill it easily by ecquiping the two following accessories to one of your party members: The Shoes of Hermes(in a room in the Ancient Factory blocked off by a black barrier)and the Poo Bracelet(blue barrier chest at the Jibral town gates). With those two items ecquiped, the ecquiped person will definitely go first and definitely take the Gold Poo Snake out in one hit.

Interesting Sidenote: There's a nearby island called the Southwestern Deserted Island where you can find all other poo creatures except the Golden Poo Snake, Jumbo Poo, Corrosive Poo, and King Poo. It really helped me fill in a couple of slots in my monster encyclopedia. Platinum Poo Snake and Copper Poo Snake can only be found there. Although I have found info saying that the Copper Poo Snake can be found in the Ancient Prison, I have never seen it there. Thus, I believe it can't be found in the Ancient Prison.

Obtaining the Final War Necklace and Ultimate Weapon Bracelet
Not too difficult. I forget exactly which can be found where, but here are the locations for Mesteries Alpha, Beta, Gamma, Un, Duex, and Trois:

Mestery Part Alpha: Picked up in Mural Town automatically as part of the story.

Other locations:
Upper Mecha Base

Ancient Factory: near the exit to the Wire Highlands, at the top of the stairwell, you'll find several statues of Double Lances. Get near each of them and they will materialize one at a time. Defeat each Double Lance party and the chest with the part will appear.

A island near the coastal entrance to the Undersea Caverns

Um....I kinda forgot just now where the other two were. Oh well, I'll find and post it later. Moving on.

Excellent way to make money
Equip one person with the Poo Bracelet and Shoes of Hermes, one with the Crown of the King Ghost, and one with a Dog Collar, then go to the Southern Deserted Island and run around. You'll ocassionally see a Gold Poo Snake appear. Fight and defeat him. Repeat the process until satisfied with your wealth.

Interesting Note: The money received varies sometimes. There were fights where I got no money, and some where I got around 25,000 gold.

Obtaining the Dragon Bracelet
After completing the marriage hassle with Marumaro in Kelaso Village, talk to the Kelaso Elder near the save point and warp device. He'll tell you about five powerful dragons that together form a bracelet of great power. Then go speak with the old lady who kept switching couches in the marriage hassle event and talk to her to get clues. These are the only clues you'll get from the game about these dragons whereabouts: "South of the glass, west of the living murals, east of the auroras, near the water flowing underground, and among the plantiful crystals hidden in the cave". Here's their locations:

Phantom Dragon: On the southern coast of the Great Desert.

Blizzard Dragon: To be accurate, just use the mechat to get to a ledge west of and right beside Kelaso Village and you'll see it.

Amethyst Dragon: Near Talta Village, on the Coastal Road right beside the rubble blocking the path.

Spark Dragon: Behind a cave hidden by a red barrier in the Gul Mountains

Moody Dragon: Go to the Underground River where there's a fork, one path leading to the entrance to the Ancient Factory and one leading to a load of Kelolons. Go down the path towards the Kelolons and fight and defeat almost all of the Kelolon parties(you have to fight them, no Feild Barrier). After almost all are gone, go back to the entrance of the part of the cave and you'll automatically get a checkpoint and a cutscene in which the Moody Dragon appears.

I'll post how to beat them tommorrow along with some other things and I have a good question:

Where do I find the Trapfloorus spell?

To beat them

Phantom Dragon
This guy is the biggest pain in the ass out of all of them. All physical damage heals him and all corporeal attacks do nothing to him and completely drain the attacker's MP. I had to cast Previve constantly with my White and Black Mages to keep them and my Swordmaster alive, while pummeling him with Magic Sword attacks and Black Magic.

Blizzard Dragon
Not too difficult but took me long to beat him. I ecquiped my Swordmaster with the Bellybutton Ring of Water and did NOTHING but pummel him with Flarus Sword. Seriously, aside from Reflecta, Roar, and his triple hit melee attack, all he can do is Ice Breath and a Blizzard attack. I have fought and defeated him twice(restarted my game file again mid-game), so I know from experience that he almost never attacks with his melee attack twice in a row, so I didn't even have to heal him to keep him up. He would melee my swordmaster then HEAL him with an ice attack.

Spark Dragon and Amethyst Dragon
With both I used the same strategy: Keep either everyone or my Black Mage, White Mage, and Swordmaster alive and pummel the dragon continuously with corporeal attacks. It took about five corporeals to kill the Amethyst Dragon, and around seven to kill the Spark Dragon.

Interesting Sidenote: It seems that corporeals do more damage than usual to the Amethyst Dragon They did around 2,000-2,500 damage to the others, but around 3,000-3,500 damage to him.

Moody Dragon
Just keep hitting him. Unlike the others, he's pretty weak. Hell, I took him out with one corporeal, so I believe he has less than 2,500 hit points.

Once you've got the fangs, take them to the Kelaso Elder near the Kelaso Village warp device and voila! You've got one of the best accessories in the game: the almighty Dragon Bracelet!

Good Will Looting

Here's some nice things you can take from certain creatures:

Ghost-Yeet: Ribbon
Blizzard Dragon: Ribbon
Moody Dragon: Lei
Phantom Dragon: A Nene accessory
Gold Mecha Robo: Golden Eternal Engines
King Poo: Golden Poo

All have been confirmed

Well, he never did that to me. Perhaps you had low agility characters(all dragons except the Moody Dragon have extremely high agility).

Also, for anyone who has trouble with the Spark Dragon, here's a good idea I found:

He has an earth and wind attack, so put a black mage and a white mage in the back row. He uses Black Wind much more often than Ancient Force, and it's more powerful than Ancient Force, so equip your white mage with a Wind and Earth Bellybutton Ring and your black mage with a wind bellybutton ring.

You can get two Bellybutton Rings of Wind in the game. One from a chest in the Underground River and one by stealing from either the Landshark in Nene's fortress or the Landshark in the Ancient Ruins Forest.

The only way I know of to obtain the Bellybutton Ring of Earth is to steal it from the Azure Sentinel in Nolutta Village.

Pound away with flarus sword with your swordmaster and heal everyone with your white mage(my white and black mages knew white magic, and I had to make both keep healing).

I basically let him damage me and did about 7 corporeals on him after about 25 minutes, killing him.

Wow, I didn't even notice this was my guide until I actually looked at teh username. Back to updating this thar topic then!

I just recently downloaded the New Game + mod. I am playing the game on hard mode and intend to play it through at least 1-2 more times on hard mode after this one then try impossible mode.

On impossible mode, the Landshark owned me in teh very beginning, sometimes taking 2-3 attacks per turn and doing about 250 damage per turn, so I need to get Shu and the others to a point where even without shadows, they have near 999 HP, and decent attack. I intend to attempt to get everyone to level 90-100 before attempting this as well, and getting all of my guys agility to near the max level, which I presume may be 999(for the King Poo battle).

One of my favorite tactics is using Marumaro as the ultimate shield.

Specific Accessories:
Bellybutton Rings of Water, Fire, and Wind

Skills:
Accessory +3
Skill +8
Total Gaurd
Barrier Magic Lv. 6
Absolute Counterattack
Long Ranged Attack
Meditate
Double Strike
Double Cast
Spell Duration +50%
Quick Magic Charge

He will protect all allies from single target attacks, absorb all magical fire, water, and wind based attacks as health, and strike back no matter where the enemy is, plus he'll attack twice. With Double Cast, Quick Magic Charge, and Spell Duration +50%, he'll be very useful for creating barriers for further defense. Another idea is to replace one of the bellybutton rings with Acorn Shoes, so he'll automatically move to the back when low on health, but against enemies like King Poo, I definitely wouldn't recommend doing so(especially on hard and impossible mode). I also have Jiro, Kluke, and Zola using high level support magic, Shu with Magic Sword, Long Range, and Double Attack(among others), Jiro and Kluke using high level black and white magic, and Jiro using high level barrier magic. They're support, Marumaro's my shield, and Shu's my tank.

Another great idea is giving Marumaro the life crusher bracelet.
