BladeGarrurumon
When you Digivolve Wargrowlmon and Kumamon together to make BladeGarrurumon, his attack will only be strong to the tolerances your Digimon have.

Fuiginmon (Digimon of Speed) is only weak to Fight attacks. If you have a Gallantmon or Cannondramon, he will go down quickly. Next is Suiginmon (Digimon of Power). He is weak to water and ice attacks. His Fight attack hits you four times -- have some Ultracharges ready. Last is Rajinmon (Digimon of Thunder). He is fairly easy if your Digimon are trained well. Water and ice attacks work on him. After all of them are defeated, prepare to take on Galacticmon.

Easy Bits
Go to the Jungle Shrine in the Ether Jungle and keep fighting Numemon (Blue). You will get an easy 660 bits every time you defeat him.
Note: You must have a Counter Crest, low defense, high attack and any elemental accessories on your Digimon for this trick. Go to South Badlands or North Badlands E in Amaterasu. You may encounter Numemon (light blue or so). Before you fight him, equip the Counter Crest and the elemental accessories. When you fight him, you can attack him with the "Fight" ability or a special attack. When he attacks you, counter it with the Counter Crest. It does the same amount of damage that he did to you, and with the low defense, it should do even more damage. Also, with the elemental accessories, it should do slightly more damage to Numemon. After you defeat him, you will get 399 experience and about 1110 bits.
In Asuka City at the inn, go to the left of the door and down the ladder. Go through the door that should be to the right of you. You will go through a underground passage. Turn left and follow that path until you rach a little place where the screen switches. There should be a box there. Open it for 300 bits.
Easy experience
Tag in all your weaker partners first, then tag in your strongest last. Do not forget to heal them to get the experience. Then, finish with the strongest Digimon. All the digimon will get the same amount of experience.
Note: This trick requires a controller with a auto-fire feature. Go anywhere where you can kill the enemies in one hit with attack. Set the auto-fire to X and use a rubber band to keep X and the D-pad held. Allow the game to remain in this condition for an extended amount of time.

Mobius Desert
Use these directions to get out of the Mobius Desert. Start at the top right corner, go to the top left corner, the bottom left, top left, bottom, then finally top left. You should be at the Mirage Tower.
Monmon
The two-handed weapon you get with Monmon at the heavy armory after you get past Mr. Smith gives you a good chance of confusing the enemy; especially with Armormon you learn at level 20 and with an attack such as Bug Buster. This still gives a chance of confusion and a better hit against certain Digimon.
New partner Digimon
There are eight partner Digimon you can get. They are Agumon, Patamon, Veemon, Guilmon, Renamon, Kumamon, Kotemon, and Monmon. After the first three you get, you will need to find the Ultimate level Digimon for the rookie that you want. DRI people are in various locations and they will tell you which Ultimate Digimon they want DNA from. Defeat the Ultimate level Digimon to get the DNA. Take it back to the DRI person that wants it and you will get that rookie. For example, talk to DRI person in Tyranno Valley. He wants DNA from MetalGreymon. Go to Bulk Swamp to find MetalGreymon. Fight and defeat him to get the DNA. Take it back to the DRI person and he will put Agumon in your team. Go to Digimon Lab or see Piximon to switch to Agumon.
Permanent Digimon
Use the following trick get permanent Digimon such as Paildramon or Omnimon. For example, to get Paildramon permanently you must have a Digimon that can digivolve to Exveemon and Stingmon at level 5. To get Omnimon as well you must have a Digimon that can digivolve to Metalgarurumon and Wargreymon at level 40.
Raising your Digimon
If you are stuck on a hard Boss Digimon, stop trying defeat him and take the time to raise just one Digimon until it is strong enough to defeat that enemy.
Recommended Digimon
Get Guilmon and Renamon. When they digivolve to Mega level, they will be a strong team (Gallantmon and Sakuyamon).
Retreating
If you do not want to battle and just want to get to a save location, place your strongest Digimon in front. When you get to a battle, it will hopefully be strong enough to allow you to run away.
Shortcut to Amataraso server
If you can call digmon then you must go to a hole and go north/south to get there. If you are in Amataratso you can go north to get to Asuka and South to Amataraso. I mean it can only happen if you are in a hole.

Mirage Tower is easier to get to than most people think. The desert is a 5x5 box that loops around itself. When you want to get to the tower you enter the desert and your in box 1-3. Go DOWN to box 2-3, than DOWN to 3-3, than you go to the LEFT side of the screen through 3-2, LEFT through 3-1, and LEFT one more time will be Mirage Tower.
