After you have taken enough damage, and you yourself have inflicted damage, there should be an option above the attack that reads 'Corporeal'. It basically turns you into a real monster for a short while, and you will auto kill anything around.

You can find the hidden Boss, Moody Dragon, while leveling up your characters in the Underground River. This Boss is found at random, so this may take some time. Try being at level 27 or above to defeat this Boss. Just use physical attacks, or anything except Shadowa. He has about 2,500 HP. Upon defeating this boss, you will get a nice reward.

If you are looking for the All Item Achievement, you will be looking for all the 1800 "nothings" and trading them to the Nothing Man in Jibral (or the Nothing Robo Mecha in Split Worlds) for items; exploring every other chest in the game will pretty much help augment your item collection. However, there are two accessories you must steal from two different bosses or you will not complete your item collection.

Be sure to steal from the Phantom Dragon south of the Glass Spires on disc 3 for one accessory.

Be sure to Loot or Steal from Ultimate Szabo in the Primitive Cube (Cauldron Room) on disc 3 for the second accessory.

At the end of the Underground River area should be a location with a large number of Kelolon monsters. Use the "Fleeing enemies keep running" glitch to cause the Kelelons to keep running until they all run into the invisible wall that prevents them from falling off the edge. This may take some time as they slowly move sideways across the invisible wall. Eventually ten or more of them will get close enough for you to attack all of them at once. Make sure you keep your Stealth active this entire time or they will jump into the ground and hide, forcing you to start over again.

Use the following trick to get this achievement easily while defeating all unique enemies on this airship. Make sure one of your characters has field barrier. Start each by floor defeating the two or three characters that are unique then activate your field barrier. You will not have to kill them again. Bouncing into them and instantly killing them costs no time, while a regular fight takes about thirty seconds. It will be easy to complete this level in about 40 minutes.

Immediately after the scene where the strange voice tells your characters to swallow the light spheres (after fighting the land shark), there is a chance to gain at least three or four levels in both class rank and character level. You have the choice to escape using the Mechat machine, but do not. Instead, fight the horde of robot enemies. This may take awhile, but the experience gained can really help your characters for what lies ahead. The Underground River area on Disc 2 is a good location to level up your characters fairly easily. Go to the end of the area where you can find lots of the Kelelon things then just battle them again repeatedly. They will always respawn. Try to use R to surround as many monsters in your radius as possible. The Underground River is also well known for having lots of other respawning monsters.

When you first visit Nene's castle, you will come across red tripwires that, when tripped, will result in an enemy encounter. After you fight the boss in the castle, you will come across a long room with a treasure chest within. In the very beginning of the room, there is one of the aforementioned red tripwires which will result in an enemy encounter if tripped. If you use Field Barrier here, you can run back and forth all the way down the hall and back to the tripwire, you can spawn a new enemy encounter each time, which is an incredibly easy way to earn SP.

Have any one character get to Rank 50 on Barrier Magic to obtain Field Barrier 3. Then have that same character get to rank 8 on Black Magic to obtain Regenerate MP. While you walk around destroying enemies for SP without fighting, you will regenerate the lost MP and never run out, effectively giving you an unlimited SP gain. A perfect area to do this trick is in the flying fortress just after Zola leaves the team and goes through the other warp. In the room just before you meet Szabo are three lasers. When set off, a flying Mecha Robo appears for each one. Each monster will result in a 2 SP gain. Just run from the save point through the lasers and back to the save point. Continue running this path saving in between when the lasers stop dropping monsters.

When you reach the primitive cube, before you enter the ruins, outside you will find butterfly monsters. Activate Field Barrier 3. Place your character in the center of the field and tape the Left Analog-stick Up and Right Analog-stick Right. If done correctly, you will run around killing endless spawns of these monsters for +2 SP each. This is best done with MP Regeneration. You can reach level 99 in a Shadow in less than an hour. Check regularly in case of skill obtaining, and also if the butterflies get in a perfect chasing distance. If they do this, activate the barrier again and continue. This trick is also best done with Eyepatch or Black Belt.

You must have the field abilities Stun Bomb and Stealth. Go towards an enemy that normally runs away upon seeing of you while under the effect of Stealth (for example, Kelolons). Toss a Stun Bomb at the monster. If done correctly, after the Stun Bomb loses effect on the monster it will begin to flee. However because it cannot see you because you are under the effect of Stealth, it will keep running until you become visible again.
