Special monsters:
There are certain monsters you cannot make through combinations and must get 
through discs. They usually have a unique look, relating to the disc they have been 
spawned from.

Adventure + mode:
Successfully complete the game. Once done, wait three weeks. After the third 
week you will get a visit from Mr. Karnab. He informs you that new passageways 
have opened in the ruins that you have. Go to adventure and press Right or Left to 
switch from normal adventure to Adventure +. Adventure + is much harder then 
normal adventure. All the wild monsters are "S" rank, and the ruins have many 
levels (about 10). Of course, the items are much better in Adventure +.

Train Pheonix:
Successfully complete the game and save it once the credits are done. Then, 
reload your game. Two weeks after you completed the game, a feather from 
Suzaku is left behind. He asks you to train a Pheonix, and tells you that the feather 
allows you to revive a Pheonix from a disc. From this point on you can revive 
Pheonix monsters.

Easy wins:
Here's a good tip for beginning monster ranchers: when training a monster, raise 
every stat to at least level ten except for power and accuracy, which should be 
raised to at least level 20. During a battle, such a monster will usually be able to 
attack past an opponent's defence and can deliver KOs easily.

A very easy way to go through the storyline quickly is to get a monster dedicated 
to Power and Accuracy, Train it in Power and Accuracy mostly, but have all its 
other stats at level 10. The power and accuracy easily raise to level 20 to 30. Most 
monsters through E, D, C, B, and A classes will not be able to dodge your attacks, 
and they will be KOed in one to two moves. This works well against Bosses and in 
dungeons, since they attack rarely which leaves them wide open for quick attacks 
that will do devastating damage. Having 700 Power and Accuracy makes the final 
Boss very easy to defeat in both forms. Note: Monsters such as Bleakons are 
perfect for this, since their Power and Accuracy are raised quickly and easily. 

Easy training:
If you have a new monster that has trouble in adventures, use this trick to get it 
leveled up faster. Go to an adventure, it does not matter where. Make sure you 
have a powerful monster in your party. Battle an enemy, and instead of KOing 
them with the powerful monster, weaken them so that they only have a sliver of 
life renamining. Then, switch with your weaker monster and allow it to finish the 
monster. The experience will be rewarded mostly to the weaker monster. This is 
an easy way to give it experience and allow it to gain new attacks and abilities. 

Delete your monster:
If you happen to accidentally get a monster you do not want (usually by pressing X
too fast when regenerating monsters), you can get rid of it for good. When you go 
to the association and select "Retire", the lady will ask you if you want to freeze it. 
Tell her "No". She will then ask if you want to retire it. Tell her "Yes". It will not use 
up a spot in your freezer and you will get rid of an unwanted monster.

Get rid of unwanted traits:
When you fill up the traits on your monster's data you can get rid of unwanted 
traits like Genius. To do so, level up until you get another trait. You will be asked if 
you want to delete a trait to make room for a new one.

Increased monster stats:
It seems that a monster that you use directly from a CD or DVD has better stats 
than one that you use from the book.
