Easy experience points
After you get Lucia and before you fight the Guardian, stay in the tower and fight monsters to gain experience points and levels. You will need them to fight the Guardian.
To gain levels late in the game, you can fight the Chiro enemies in the White Dragon cave. You need to be at level 50 so that Hiro can use Triple Sword. Keep in mind that the Chiros will usually run away after one round. When you go into the battle, use everyone's strongest attacks. A victory will net 33,333 experience points and 11,111 silver. This is especially helpful immediately before Zophar.
Use the following to get easy experience after Zophar/ Go to the area near Neo-vane's crash spot to find a place called Lionhead. There are some very tough enemies there. Find the one called Dark Sphere or something that looks like those black spheres that use electricity in some of the other dungeons. This thing is hard to defeat without having Leo's Soul Blade because all normal and most magic and technique attacks only hit for 1. To battle it, have Hiro defend. Have Ronfar use Angry Dice and revive and heal people. Have Lemina use Catastrophe if she has it -- if not, defend. Have Jean defend. Leo should use Soul Blade, which will do 200 to 300 damage on the enemy. After about three or four turns it should die, resulting in 22,222 experience points. An alternate method is to have Hiro use Concussion Sword and everyone else defend.
In Neo-Vane, at the Cave Of Trial, you can get free experience points from the Scorpion enemies. You should have the normal battle positions as the game has it set, and give Lemina the Ice Staff so she can hit the enemies with an ice attack. When you fight the Scorpions, have Jean and Hiro attack the top Scorpion. This will push him back. Ronfar will not be able to attack because of his range. Then, have Lemina attack the top Scorpion. If done correctly all three Scorpions will be defeated for 560 experience points.
You can do this before or after Zophar. Go to White Dragon Cave and find Chiros. They are the enemies that have a very high defense and runs away after one turn. Have Hiro use Triple Sword, Lemina use Catasrophe, Jean use Blue Dragon Fist, and Leo use Soul Blade. Equip Ronfar with Earth Crest/Thunder Crest or Water Crest/Thunder Crest or Water Crest/Fire Crest or Fire Crest/Wind Crest combinations so that he can use Pulse Explosion. Use it on Chiro and it should die. Without Pulse Explosion, Chiro will not die.
Make Ruby kill a leader
When you fight the Guardian, get Hiro and Gwyn to trap the Guardain in the corner and keep Lucia alive Let Hiro and Gwyn die, which makes it a stalemate. Ruby will jump in and kill the Guardian. This is a event that foreshadows the Ruby Red Dragon transformation.
Dashing item combo
Equip a character with the Yellow Pajamas, Gorgon Doll, and Rubber Boots. Now your dungeon dashes will last four times the usual duration, with the catch being the PJ-wearing character will be asleep when you inevitably get into a fight.
Crest combos
Place the Chiro Crest and the Shiro Crest together to get a decent amount of speed and 200 range. Place the Thunder Crest and the Wind Crest together to get Thunder Wind magic. Place the Power Crest with any Crest of magic (Mute, Poison, Thunder) and your physical attack will sometimes inflict damage/status of that crest's type. Note: You must have both crests on the same person.
The following combos have the corresponding effect.
Power/any crest: stronger magic
Earth/Thunder: wearer can use Pulse Explosion.
Earth/Wind: See above
Warrior/Seal: Attack power doubled, but wearer cannot use magic or skills.
Wind/Thunder: Wearer can use Lightning Rain, Plasma Shock, Wind Cutter, Squall, and Thunder Tornado
Shiro/Chiro: Speed +10, Range 200!
Chiro/Chiro: First attack, Speed +10
Snake/Revenge: Attack more each round
Mind/Warrior: Attack last, Attack +45
Healing/Magic Eye: Attack with absorbing enemy's MP.
Water/Thunder: Wearer can use Pulse Explosion.
Water/Fire: See above
Fire/Wind: See above
Fire/Thunder: Wearer can use Lightning Rain, Plasma Shock, Flame, Flame Bomb, and Shining Flame
Fire/Earth: Wearer can use Rock Viper, Rock Crush, Flame Bomb, and Burning Quake
Water/Earth: Wearer can use Rock Viper, Rock Crush, Ice Pick, Ice Lance, and Icicle Break
Water/Wind: Wearer can use Ice Pick, Ice Lance, Wind Cutter, Squall, and Mighty Mistral
Gale/Hunter: Projectile attack
Archer/Ogre: Range+
Goddess Crest
Put the Goddess Crest on a warrior and your attack will increase dramatically.
Put the Goddess Crest with the Gale Crest (found in the dragon's nest north of the Holy City in the Epilogue). It will increase your number of attacks.
You must have the Goddess Crest and the Magic Eye Crest. You no longer need to use a lot of your magic. For example, Freeze Smash (Lemina's Magic) normally uses 20 MP. However, if you have the Goddess Crest and the Magic Eye Crest this will be reduced to 10 MP.
Raise range
Combine Shiro and Chiro Crest will raise the player's range to 200.
