Tips & Tricks
These tips came straight from Zenodeus' Walkthrough/FAQ.

-Talk to everybody more than once. You'll get funny bits and useful information.
-Search everywhere and everything. Items are hidden in the most unusual spots in the game.
-Remember in battle, the IP gauge is your friend. Know when's the right time to attack, defend, and cast spells.
-Try your hardest not to be ambushed before a battle. The enemies may get two or more attacks off before you can do a thing.
-Keep an eye on the compass and where your characters are so you don't get lost.
-A good strategy for getting tougher is using a ton of magic spells in battles (to increase magic exp) then run real quick to a save/recover point.
-Switch weapon types occasionally to keep a good balance in necessary ones.
-Boss strategies: using Critical attacks will knock the bruisers back on the IP gauge and may not even let them attack. I beat the first boss using this method and didn't get hit ONCE.

-Raising magic is hard, especially the early stages of water magic so what I did was always use "Heal" in my menu to heal my party and then replenish my MP at a save point.
-You get more magic experience by hitting groups rather than single enemies. You also increase your maximum SP and MP by increasing the star ratings on your specials (the max is five stars).

-Also when talking to people, you can get special items if you answer their questions correctly.
-Enemies drop useful items and weapons, so fight all different types to get different results.
-Change the camera view to find hidden items and enemies.
-When it's a character's turn to choose a command in battle and an enemy is about to attack you, select defend and then evasive so the enemy will miss you.
-Examine odd looking pictures on the walls of dungeons. They could be a secret door that leads to a secret passage with useful items.
-Combat is your friend, not your enemy. Spend a couple of hours every once in a while to raise magic and weapon levels. Since your stats boost at those levels go up, you won't regret it.

-To get more SP easier, try using the moves that attack groups, ie. Justin's Dragon Cut (Gadwin's), Feena's Fire Whip, and Rapp's Neo Demon Ball. For Justin and Feena, you'll also get lots of magic points, which is useful to raise Feena's Lv 2 MP for using World End. Equip the appropriate weapon to raise your
stats, too.
-Try not to use magic spells that always attack all, like Zap All because the points you get aren't as high as a normal spell like Burn, Howl, or Quake.
-Give Liete a telescope because she's not good at close range. She's more useful for her magics, using items, and her critical move.
-The sleep spell is useful for raising your water level later in the game. If a particular character doesn't have sleep, they may have Freeze, which you can use instead. Diggin' works the same.
-Using a MAXed move also raises other moves' stars.
-You get maximum experience points from the enemies that appear near your next location. For instance, if you're supposed to go the Savannah, you'll get more exp. points for your level and your weapon's level than from defeating baddies in the Zil Desert.
-Against bosses, equip most of your characters with a +1 combo/critical attack accessory. While three of your characters are hitting the same enemy, use the other to add a critical attack. Works well on single bosses with no different parts.
-Equip slow-moving characters with a warp capable accessory.
-If the enemy is at the act point and you can't reach it in time, try using a MAXed magic spell (Burn) to slow them down, just in time for your other characters to get in.
-Don't give WIT-raising items to Feena, since her whip does it automatically and its her main weapon.
-A good, fair way to raise levels is to kill all the baddies in an area before proceeding to the next.
-At the volcano near Gumbo, killing enemies sometimes gives you a fire weapon. Keep collecting them, then sell them because they give you a lot of money early in the game.
