You can normally unlock 31 dreams. There is actually a 32nd, optional one.
Before leaving Uhra for the first time, return to the Main Street and visit Virno's Tavern. Approach the soldier in the counter to unlock the dream; A Heros Return. Go upstairs and talk to standing man overlooking the balcony. Unlock another dream Samii The Storyteller (#32).
Antidote Brooch
Before leaving Uhra for the first time, go inside "The Great Gate - Inside the Tower". You will find a guy beside the elevator named Colen. He is looking for a soldiers helm. After learning some clues, take the elevator up then down. Now, after getting off the elevator, guide Kaim to the right. Ram should be the action command available. Do so and the helm will fall down. Pick it up and Colen will approach you and will reward you with an Antidote Brooch.
Backyard Special Class: The Immortal
This boss has a whooping HP175,000. Youll need all your luck here, as well as all the best equipment and skills you can get your hands on. Fortunately, I was able to defeat this guy during my first fight with it. First I will list down the things you should expect:
Sneeze This move will instantly destroy your GC, leaving your mages very vulnerable. No need to waste turn by recovering GC since this boss only needs one turn to destroy the GC you are trying to recover for several turns.
CUBE - This dreaded move deals percentage damage, leaving your party with an estimated 1% of their HP; it doesnt matter if the characters have full HP. In an instant, it will become critical
Shadowus Though damaging, this is entirely bearable, especially when you have the Angel Heart + All-Generatus combo active. This is the most frequent spell the boss will use, since your party has immunity to elemental attacks anyway.
All-Curse Can be observed as its primary counterattack move. Make sure that your mortal character has Angel Guard.
Divide Hopefully, it wont use this spell while it still has a lot of HP. If it did, hope that some of your characters absorbs the damage or activate Persistence.
At this point of the game, you should have a fair amount of Goddess Medicine in your inventory. Use this only in tight emergencies; this will serve as your life saver. Next, avoid using elemental attacks. Dont be fooled by thinking that this monster is weak against wind attacks; Windus will only deal 1 or no damage at all. Hunter Rings or Sniper Rings are great for dealing extra damage to the target.
Your chance of winning here is Divide and Reversa. Divide deals damage according the users current HP while Reversa deals damage based on the amount of HP the user lost. This monsters physical attacks are no joke either; each hit can take out anybody whose HP is below 8000. Persistence, Absorb Attack and Absorb Magic will play a great role here. Just remember to have at least one member dedicated to healing and recovery. Keep your partys HP to full as much as possible, and use recovery items if needed. This will be a long battle. Once the boss HP becomes critical, it will start casting Cube and Shadowus before your mages can cast their healing spells. Having Auto-HP recovery will help a lot in keeping your party afloat. Good luck!
Achievement will be unlocked after defeating this boss. You will also win the Quad-Element Seal for fulfilling the bonus objective. Now you can trade all your collected stars to get the prizes.
Completion bonus
Successfully complete the game and save when prompted after the ending credits. Select "Continue from the save file" to keep your characters intact in the next game session.
Crossing Hypercurrents
There are certain parts of the sea that you can't access due to hypercurrents. Clear the Great Ancient Ruins in Disc 4 to unlock this ability.
Easy experience
Make sure your entire party is at least level 44. Have Kaim and Seth in the front row as power hitters, and have the three people you want to level in the back row. For example, start with the formation of Kaim and Seth in the front and Sed, Jansen, and Ming in the back. Rotate the mortals out as you learn their skills. Go to the Temple of Enlightenment. Make sure you have an abundance of Mana Rechargers, and run around the diamond-shaped track by the save point. If you stay in this area, you will fight only three types of easy monsters, giving you lots of SP and experience points, but not much gold, You will fight a black Kelolon (weak against Ground magic). In another battle, you will fight three exploding poison monsters. They repeat the same strategy every fight; try to stay one step ahead. The third fight is against four wind element bats and three fire element nymph-like creatures. If you keep Seth and Kaim in your group (take advantage of Sed's experience point and SP skills), you will level up quickly.
Easy money
Loan the bad gambler a total of 10,000 gold, and he will pay you back a total of 50,000 gold.
Finding Invisible Chests
In the Pirate Fortress, there is a penguin in the eastern platform. Follow it and it will lead you to a hidden screen with the last pipot and a chest containing Cubic Music Score 9. Bring it to any Cubic Musician inside the White Boa, Numara and Uhra and play:
1 - Rest, E, E, Rest
2 - D, Rest, C, D
3 - E, G, A, B

Recovering stolen items from Elmons
In the Ice Canyon, there are monkey-like creatures called Elmons. They will occasionally steal items and accessories from you. To get them back, you'll need to recover the key item "Elmon Crown". This is hidden at the end of the secret path in the area where you fought the Dinozoara boss, along with a royal seal.
Once you have the crown, enter random battles with the elmons until one of them steals the Crown. Visit the Elmon leader and his gang in the small path in the Ice Gorge area.
Talk to him twice and you will be thrown in a battle. After winning, you'll get a Mind Bangle accessory and the Elmons you face from now on won't steal from you anymore.
Recovering stolen items from Trookies
In Great Ancient Ruins, there are Elmon-like enemies here that steals items and accessories. To recover the items, find the "Trooky Talisman", a key item inside a chest inside the ruins. Clear the ruins first (defeat the boss) and return again. Head to the Lunar Palace's bottom floor and find the Trooky Queen there. Talk to her twice, defeat her to get Sorcerer's Bracelet and recover your stolen items back. Also, enemy trookys won'g use the steal command ever again.

Secret Boss: Blue Dragon (Disc 4 only!)
Note: Requires White Boa.
Break the ice in the NW part of the continent until you get the prompt to land to the "Snowfields of the Northern Land"
Jansen will remind you that a legendary spell can be found in this area. Also, youll notice that your partys HP is slowly being drained. This is some sort of a little maze. Just head to the direction where the wind/particles are coming from. Do this for at least 5 times and youll encounter an optional boss battle.
Boss Battle:
Equip some good rings with Bio-Killer skills. This boss absorbs elemental damage so it will be a good idea cast healing and support spells instead. It takes turn twice (probably because of doublecast) Its attack patterns seems to be fixed; Prisma and Death/ Leveler/ All-Curse and Forceus. Leveler deals considerable damage but fortunately, it can only target one character. With only HP9350, this batlle shouldnt take that long. Just make sure you equip Anti-Curse for your characters and avoid healing the boss with elemental attacks. Gamble works fine, but I suggest leaving the offensive to your frontline. Buff them with Powerus with Bio Killer Skills and this boss is a goner.
Aside from the Blue Dragons Eye accessory that youll get as battle spoils, youll also get LV8 Black Magic: Leveler. The corresponding achievement for this battle will be unlocked as well.
Secret Boss: Caveworm (Disc 4 only!)
Note: White Boa required
To the north of the main continent is a small inlet that is blocked by ice. Break the ice using the White Boa, then launch the Nautilus. Dive and you'll find the entrance to the Forgotten Cave. Loot the items in the area and fight a secret boss in the upper level.
Seth will be a fixed character here. Equip your attackers with Bio-Killer rings. This enemy can deal massive damage by attacking characters consecutively. Make sure to cast All-Generatus and other support spells to everybody and attack buffs to your attackers. Forceus works great, while having Perfect hits against the enemy further increases your damage potential. With just HP10000, this battle shouldnt take that long.
After the battle youll receive Gravity Rave (Seth only) and Gravity Ring. You will also receive Aneiras Plume and unlock the corresponding achievement for defeating this boss. Now time to get the remaining items. Jump to the west side to get (x6) Forbidden Explosives. Head north from the main area to reach a small deadend with a chest containing (x6) Ruin Masks. You may not leave the cave and head to the Numara Atoll.
Secret Boss: Golden Knight (Disc 4 only!)
After breaking 8 Royal Seals, head back to Uhra and proceed to the Castle. Take the elevator there to find the last Royal Seal. Remember that you can't break it if you haven't broken the other 8 seals. Break it and the Golden Knight will appear.
Tolten will be the only one in this battle. For the first few turns, you can only "Accept" the challenges. And a few more turns, you will have full control of Tolten but I suggest healing yourself until the Knight mentions something about "protecting oneself". By that time, make sure to use Tolten's Complete Defense skill. The Knight will use the Ultimate Hit skill that will surely kill Tolten without Complete Defense active.
After enduring the attack, Tolten will learn the skill for himself. Use it against the Knight to end the battle.
After winning the battle, you'll get the Age of the King sword and King Ring. You'll unlock the corresponding achievement as well.
Secret Boss: Holy Beast (Disc 4 only!)
You'll need to get Ming's Harp first. Enter the White Boa and proceed to the ship's Guest Area then eventually to the Queen's Chamber. Once you have the Harp, wait until you have access to Numara Atoll. Go there to start a scene and summon a beast.
This battle isnt hard. Just equip Anti-Sleep or Ailment Resistance skills. Beast-Killers and Earth effect rings are your best bet on winning this battle. Forceus can also deal massive amount of damage to the enemy. Cast the usual healing and support spells first. Having Null All Elements skill equipped is also essential for blocking its All-Groundus and All-Aquaus attacks.
After the battle you will obtain the 1000 Year Memories accessory. This exceptional item allows your immortals to obtain +10 more skill slots, which is stackable from the existing +3 and +5 skill slot skills.
Here's the tip to defeat this optional boss deep inside the Temple of Enlightenment.
During his first turn, he will use Obsidian Ceremony to summon an Obsidian Miasma. Casting support skills here can be troublesome since he loves to use Delete to remove all beneficial effects from your party. Also, he wont be targetable while the Miasma is active. Concentrate your attacks to it first. Equipping Spirit Killers will be a great help in this battle.
The Miasma shouldnt take that long to defeat; especially if you often land perfect strikes with the Spirit Killer 3+ active. You can also cast Divide to defeat it faster. After the Miasma is defeated, the Sorcerer will summon two more reinforcements.
These enemies are weak to fire to have your mages dual-cast Flarus. Having Fire LV3 skill like the Sun Ring or Flare Ring can deal enormous amount of damage to the targets. Each of these souls have around 22000+ HP, making a formidable GC wall for the sorcerer. Fortunately, these guys can be disposed easily within 2-3 turns. Once the two targets are down, start attacking the Spirit Sorcerer Fu. He has some really good attacks so dont let your guard down. Heal often as All-Generatus is your friend in any battle.
After the battle, you will obtain LV8 Spirit Magic: Sacrifice Self.
Secret Boss: Money-Money
In the Great Ancient Ruins, there are uncommon enemies called Moneys that sometimes steal your gold. Let them be for the meantime.
After clearing the dungeon, return to Terrace Cave and find some sparkling stuff on the floor. Pick them up (each is worth 1G), as it leads the trail to the NE. Find a chest after the last coin. Open it to enter a battle with a secret boss named Money-Money. Defeating it will reward you with another hint-book for the Backyard Battles in Gohtza. You will also recover all your stolen money back.
Secret Boss: Persona (Disc 4 only!)
Visit the Old Sorceress' Mansion after clearing the Great Ancient Ruins. Once there, Sarah will mention that she needs to retrieve a notebook. If you have the hint or clue about the 24th treasure, it can be found here as well.
Head to the Hermitage and to main room to enter an optional battle against this secret boss:
Kaim and Sarah are fixed characters for this battle. Have some status protections skills, like Anti-Petrify, Anti-Darkness and Anti-Paralysis. This boss loves to use its own version of Darkness, which damages the whole party, making them lose MP as well as inflicting the Dark status ailment.
Persona has two sides. The normal face absorbs magic while the knight/helmet side absorbs physical attacks. Switch your attacks accordingly. It only has 12000+ HP but this battle can be very hard if you dont know the proper strategy. Casting all generate is good. If your casters have learned Double-Cast, then the better. Just make sure your frontlines have Casting Support skill to make the casters turns faster. Also, this boss has an instant death attack, fortunately, effective only to one target at a time. Just cast All-Cura if your characters have multiple status effects. Using All-Generate for all characters should be a good support for keeping their HP refreshed.
After the battle, you should also get Sarahs Notebook as a bonus for this battle as well as the corresponding achievement.
