Hints:

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. 

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. 

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.

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.

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.

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. 

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.

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

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

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.
