The Boss is Parasite Dragon, Level 30, HP: 9999, SP: 305, Skill: Ranki Lei, Items: 3x Hyrakkidouran. To defeat this boss, you must use the following characters: Kite, Choice of Heavy Blade, Heavy Axe or Blademaster, and Wavemaster; along with these items.

Equipment for Kite or Long Arm User:
Weapon: Dante's Blades or Hell's Gate (Twin Blade), Fiend Spear (Long Arm)
Helmet: Fire Dance Hat
Armor: Firedrake Mail
Hand Armor: Miner's Gloves or Smith's Gloves
Leg Armor: Fire Lizard
Equipment for BlackRose, Blademaster, Heavy Blade, or Heavy Axe:
Weapon: Claymore (Heavy Blade), Jinsaran (Blademaster, Secret Rare Blademaster Sword) or Sun Fang One or Kikujyumonji, Devil's Axe (Heavy Axe)
Helmet: Hunter's Hood or Forester Helm
Armor: Blaze Armor
Hand Armor: Hands of Fire
Leg Armor: Electric Guard
Equipment for Mistral or Wavemaster:
Weapon: Starstorm Wand
Helmet: Scarab Earring
Armor: Lincoln Green (From Cima)
Hand Armor: Air Bracer
Leg Armor: Oak Anklet

As you begin the battle, start by using everyone's best skills at the dragon. However, do not use magic since the Parasite Dragon has Magic Tolerance. The only thing that is effective on the dragon is physical attacks. Use both Kite and the Heavy Blade, Heavy Axe or Blademaster attacking the Dragon while the Wavemaster heals you. Because of the last battle against Skeith, you should have a lot of Resurrects. Keep attacking it and heal often. The dragon can do damages of 400+ for the fire breath and 500 for each of the two bite hits. Once finished, a short intermission sequence will show Kite saying that the monster made the airship into a flesh airship.

Defeating Skeith  -  Buy many Resurrects, Healing Drinks, Antidotes, Restoratives and Mage's Souls. Have your party at least at level 30. Take a person with a lot of damage in your party, and equip the best equipment there is, as follows:

Equipment for Kite or Long Arm User:
Weapon: Dante's Blades or Hell's Gate (Twin Blade), Fiend Spear (Long Arm)
Helmet: Fire Dance Hat
Armor: Firedrake Mail
Hand Armor: Miner's Gloves or Smith's Gloves
Leg Armor: Fire Lizard
Equipment for BlackRose, Blademaster, Heavy Blade, or Heavy Axe:
Weapon: Claymore (Heavy Blade), Jinsaran (Blademaster, Secret Rare Blademaster Sword) or Sun Fang One or Kikujyumonji, Devil's Axe (Heavy Axe)
Helmet: Hunter's Hood or Forester Helm
Armor: Blaze Armor
Hand Armor: Hands of Fire
Leg Armor: Electric Guard
Equipment for Mistral or Wavemaster:
Weapon: Starstorm Wand
Helmet: Scarab Earring
Armor: Lincoln Green (From Cima)
Hand Armor: Air Bracer
Leg Armor: Oak Anklet

To defeat Skeith, distribute twenty Resurrects to each person in the party, then thirty Healing Drinks and twenty of Antidote and Restoratives. Do not distribute the Mage's Souls. Use the entire group at first and use skills. If Kite dies, press Square for "First Aid" and afterwards, just keep hitting him without skills. Once you get enough for data hacking, use it on Skeith and you will see his second form. Because of this, just do a hit and heal combo so you will not get major damage from the shockwave hits. Keep repeating this combo so you will not die. And if you do die, keep using "First Aid" and keep slashing away.

Defeating The Goblin Kings  -  Going through a set number of events, a message will appear on the board called "Let's Play Tag". In this message, there will be a Golden Goblin challenging you to play tag. Go to the area instructed and try to defeat him. When you win, he will tell you how he is just an apprentice of the four Goblin Kings. Later, you will get extensions of the challenge note from one of the four Goblin Kings. To defeat them, get close enough to use a multi-hit attack, such as Tiger Claw or Staccato, after using an item or technique to raise your accuracy. Otherwise, most of the hits will miss. Repeat this a few times and you should defeat them easily.

To kill the last Goblin without having it heal itself, bring some Mage's Souls and Speed Charm. First, use Speed Charm to go faster. When you get close enough to the Goblin, use skills. When you run out of SP, use Mage's Soul to regain it. Keep doing and that Goblin will not have time to heal.

Getting Items Needed For Trade  -  Use the following trick to get certain items needed for trade (for example, Cooked Bile). Remember a place that has the item and go there. Once you get to a place with a lot of jars or eggs/small eggs (usually a treasure box area), break everything. If you get the desired item, exit then immediately return. The jars or eggs/small eggs have been restored. Break everything again. Note: This does not mean you will get the desired item every time. Keep repeating the process until you have enough of those items to trade. You will get items that are useful, such as Healing Potions, Healing Drinks, Antidotes, Resurrects, and Restoratives. This is especially useful just before Bosses. Also, since it is free you will not want waste any money.

Gold and Silver Axes  -  If you want to get a golden or silver axe, warp to a stage with a mysterious pool of water. You can throw in armor or weapons for level up, or recieve a free golden or silver axe.

To get the axes, take any weapon or armor and throw it in the pool. A water drop monster will come out and ask you if you want a gold axe, a silver axe, or neither. Say, "Neither".

If the weapon or armor you throw in hasn't reached a certain level, the monster will upgrade it; however, if your weapon can't grow any more, you will get a free gold and silver axes as well as get your item back.

This trade works better if you throw in a silver or golden axe in the first place and tell him you lost neither. A great way to build up your gold/silver axe stockpile, sell it for money, repeat.

Grunty Keywords  -  As keywords in the Grunty place, put in "chosen hopeless" then whatever you want. There will now be some level 30 places.

Iron Grunty  -  The only way to get an Iron Grunty is to give the Grunty what it exactly wants, even as very Little Grunty.

An Iron Grunty requires four Piney Apples, three Snaky Cactuses, and twelve Golden Eggs.

Kite's Best Weapon  -  To get Kites best available weapon for Part 1, Data Drain the Mu Guardians enough times. Eventually you will get the rare Level 14 Dual Blades.

Poison Grunty  -  A Poison Grunty requires four Piney Apples, three Snaky Cactuses, one Immature Egg, and eleven Golden Eggs.

Regain SP  -  Walk around and your SP meter will refill. This is especially useful if you have monsters to fight next. You can just wait in an empty dungeon room until it refills.

Root Town: Easy Master Supreme On The Zeit Statue Ranking  -  Go to Root Town and put the keywords "Chronicling pagan Sunny Demon". Bring a Speed Charm and a few Fairy Orbs. To find the way in the dungeon, use Speed Charm to go faster and Fairy Orb to see your way. Go to the Zeit Statue. When at Master Supreme rank, you will get Time items.

Ryu Book  -  To get a Ryu Book, use Data Drain frequently. However, do not use Data Drain can cause some damage to you. There are only eight Ryu Books in volume one. The Ryu Books keeps a record of almost everything. It will tell you if you broke a record. It will then give you a new sound or movie for your computer on the game. Note: Movie only works the game has been completed, and all movies are just some memories of what happened. Check every Ryu Book if you got everything for the computer. If it is red, it can not create any more things for you. You can only check a Ryu Book when in the server.

Secret Rare Weapons  -  Data Drain enemies and on rare occasions, you will get a secret weapon. Each secret rare weapon lowers one or more stat parameter by -10.

Secret Rare Twin Blade: Hyakkidorran (Data Drain the Parasite Dragon)
Secret Rare Blademaster: Jinsiran
The best weapon is acquired by Data Draining the Parasite Dragon on the airship. It does more damage than the Bom-Ba-Ye, is less accurate, but has more skills and magic power.

Thunder Cloak  -  Look for someone named Tim. He may be a Wavemaster wearing a green outfit. He has an item for trade called Thunder Cloak. It is a level 31 armor, and has the power to revive dead players so you will not need to use Resurrect potions all the time. It also has other secret powers.
