Hint: DVD secrets:
The DVD that is included with the game has a secret section. It reveals secrets in the game. Enter the "Data" menu and highlight the ".hack Pro Trailers" option. Press Right to highlight a circular icon. Press X or Enter to view the secrets.

Hint: Defeating Goblins:
Have some Wood magic equipped. Start the match, wait until the Goblin runs, then sits still for a moment. Then, use the magic. Goblins are all weak against Wood; two shots will kill them.

Hint: Easier game:
It is much easier if you have a Wavemaster in your party, whether it is Elk, Wiseman, or someone else; and also have a heavy blade person. This helps very much. Also keep your other members leveled up with you because you have to use them at times.
Josh Broberg.

Buy items such as Speed Scroll, Warrior Blood, Hermit Blood, etc. to have a better boosted character.

Hint: Easy level up:
Put in a random keyword until you find a significantly higher level than yours (use Kite only) and make sure what element it is. Once you reach the server, use Speed Scrolls, Warrior Bloods, etc., and items such as Burning Oil, Well Water, or magics to raise element damage. Use a Hermit Blood on Kite and raise his element damage with an item/magic (whichever element is needed). Encounter an enemy with the opposite element and you
will do heavy damage. After you level up, bring your other characters to the stage. You will notice that they also grew in levels by a bit. Use the same strategy (if needed) and raise their level as well.
Nazak.

As soon as Omega server opens enter Chosen, Hopeless as the first two parts of a keyword at that server. For the last part of the keyword, choose any one that has an element that your weapon is strong against. The monsters are not really that difficult. Your other party members that you did not bring will also get real nice experience gains. It is recommended that you take Wiseman and a lot of healing items. You can also use the keyword Chosen Hopeless on any server to get better gains.

Go to the places that the residents of Net Slum tell you about in Omega server. The four places are protected. You will fight those guardian things from Sign. Data Drain them to make them The Bracelet. They are not too strong and give you about 520 experience points. Note: The Ryu book will tell you they are level 99, but they have only 3,000 HP; watch out for their summons.

Hint: Easy weapon and armor power up:
Use the following trick to get the highest level for your weapons and armor per server. When at the Choas Gate to choose a place to go, choose "New Keywords" instead of "Random". Here is a simple formula to choose your keywords to get a Monsenor (Blue) to upgrade your weapons: Enter anything for the first two words, then "Aqua Field(Hypha)" for the last word. To get a Granpa (Red) to upgrade your weapons, enter "Lonely(Great)" for the first word, anything for the second word, then "Aqua Field(Hypha)" for the last word. To get a Monsenor(Blue) to upgrade your armor, enter anything for the first two words, then "Twin Hills" for the last word. To get a Granpa (Red) to upgrade your armor, enter "Lonely(Great)" for the first word, anything for the second word, and "Twin Hills" for the last word.

Hint: Easy money:
Go to either Delta or Theta servers. Enter any dungeon where you can kill monsters with just a few hits. Get the Gott Statues and sell those items for money.

First, empty your items, scrolls, books, treasure, and equipment (other than healing items, Fairy's Orbs, and Fortune Wires). Open all the portals and get all of the chests to sell for even more money. You can make thousands in just a few hours.

Hint: Easy battles:
Keep powering up your Wavemasters so that you can just let them do all the work. None of them will get hurt. Make sure to have a lot of Artisan's Souls.
FoxDie.

When you are going out to go to fields, choose Blackrose and Mistral in your party. They are very useful. Make sure they have strong weapons from .hack Part 1: Infection. Have Mistral equip Starstrom or Storm whatever. She will have Summonings 1 and 2 of Earth Yarthkins and level 2 Vulcan Fire. Also find an armor for her that has Ola Repth. It recovers 400 HP with anyone near the target she is healing. When in battle, have Mistral use the First Aid command and if you have to everyone First Aid.
Davis So.

It is easier to have a lot of different Twin Blade weapons so that you have various skills. For example, if you were going against a dark monster, then try to get a weapon that gives Kite thunder skills.

Hint: Exit dungeons quickly:
Whenever you get lost in a dungeon, for example one that is crawling with Data Bugs, and you need the fastest route out; or if you just want to exit, remember that you can also use the Fairies Orb inside the dungeon as well as outside.

Hint: Additional characters:
After you defeat the final Boss and the credits roll, save your game. When your desktop appears you will have new mail. Read the e-mail from Aura (which is unscrambled unlike her others). She tells you to go to Delta: Bursting, Passed Over, Aqua Field with Orca, who is now out of the hospital. Go to the bottom of the dungeon and Aura will give you the Book Of Daybreak, which allows you to use your Data Drain and Gate Hacking abilities again. After you log out, you will receive a message from Helba. She gives you member addresses for a lot of characters from .Hack//Sign, along with hers. The members addresses you get are for Helba (Wavemaster at level 99 with maxed out stats because she is a hacker), Tsukasa (Wavemaster at level 1), Subaru (Heavy Axeman at level 15), and Sora (Twin Blade at level 90). You will also receive another e-mail from Aura after receiving the Book Of Daybreak. You will get the Keyword Omega: Hidden, Darkside, Holy Ground. You will be accompanied by Elk for this dungeon; choose another character that has good strength. When you get to the last floor (there are fifteen floors and each contains many Data Bugs), you will fight a boss which resembles the guardian from .Hack//Sign and the Gate Hacked dungeons you went to earlier in the game. When you defeat the Boss, you will be able to choose Mia as a character again and receive two FMV sequences to watch on your desktop.

Hint: Rocker Grunty:
A Rocker Grunty requires four Cordycepts and eighteen Golden Eggs.
Andrew Martin.

Hint: Wooden Grunty:
A Wooden Grunty requires four Cordycepts, one Immature Egg, and seventeen Golden Eggs.
Andrew Martin.

Hint: Grunty food:
An easy way to get food for Grunties is to go to the areas where you played tag with the Goblins. There usually is a lot of food there, and no monsters.
joe kickass.

When you are looking for Grunty food in the field, call Noble Grunty and press Triangle. He will automatically track down Grunty food for you. Also, Aqua Grunty and Rocker Grunty will take you to the dungeon if you are too far away from the dungeon.

Hint: 2128 Drain:
2128 Drain allows you to Data Drain monsters. The chance of getting a rare item is high. You can get this after you have obtained all of the Book of 1000 Enhancements and after you have gotten Data Arc. After you have Data Arc, use Data Drain Many times to get 2128 Drain.

Hint: Drain Heart:
Drain Heart allows you to 2128 Drain multiple enemies. The chance of getting a rare item is high. You can get this after you have obtained all of the Book of 1000 Enhancements and after you have gotten Data Arc and 2128 Drain . After you have 2128 Drain, you must use Data Drain many times to get Drain Heart.

Hint: 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.
Carlos Lopez.

Choose Wiseman as a party member. Wiseman will always have six various items (Cooked Bile, Pure Water, etc.). Trade with him for them then log out. Log back in and call Wiseman again. His inventory will be replenished and you can trade with him again for six more of the item that you are looking for.

Hint: See Gardenia's underwear:
To look up Gardenia's dress, walk to any stairs leading down in a dungeon. Before going through the door, turn around and enter first person view. You can see up Gardenia's dress. She is wearing white panties. Note: this trick only works when Gardenia is in her ready stance. If you wait too long she relaxes and you will have to position yourself again.
Nick De Costa.
