As stated in the opening, there are 28 quests, but only 27 need to be completed. You get a margin of only 1 missable/messing up a quest..

This achievement will be a bit easier if you spared Jasmine's life at the thieves' den, then kicked her out of the party for Melusine. If you chose to keep Jasmine, you won't be able to access Quests 12 and 27 since you'll be barred from entering Melusine's castle, and Quest 11 requires Melusine herself.

Once you've done the main objective of the quest, return to the quest giver to finish it. If you prefer leaving the sidequests to the end, prioritize the following quests:

Quest 3 - you need to spare Jasmine's life at the thieves' basement. There are two cutoff points: 1) before entering Zenna and talking to Melusine the first time, OR 2) if you kept Jasmine, before defeating the Demon of Fear

Quest 11 - you need to do this before defeating the Demon of Fear. You must have recruited Melusine into the party, either by killing Jasmine at the thieves' den or abandoning her upon entering Zenna and talking to Melusine.

Quest 20 - you need to do this before returning to Izuka after killing the Demon of Ego.

Quest 22 - you need to finish it before killing the Demon of War in Clea's scenario

You'll also need the following party members:
Fox - he only joins if you've managed to recruit a lot of animals in the party. At the very earliest the most you can recruit is the Rooster, Cow, Bear, Wolf, and Horse. Required for Quests 4 and 13
Raccoon - required for Quest 13
Alex - required for Quests 10, 16, and 20
Barbara - you recruit her in Quest 17, and she is required for Quest 12

Alex is relatively easy to recruit, but the Fox and Raccoon may be a bit more difficult, so see the following screenshots:


Here's how quests are labeled:

Earliest to start?: Basically, the earliest point of the game you can trigger the quest.
Last chance: The point of no return for time limited quests.
Other requirements: Prerequisites you need to have done before taking on the quest. This can be anything from doing other quests first or recruiting certain characters.

Earliest to start?: As soon as you leave Moondrop Woods and enter Izuka

Freddy's book is found in some vines at Moondrop Woods. Examine the vines to get the book, then return back to Freddy.

If you need help finding the book, check the video.

Earliest to start?: As soon as you leave Moondrop Woods and enter Izuka

You need to talk to the Ice Cream Vendor at Zenna and buy his Joy of Spring. However, you can't properly finish this quest until after Clea and Jordan reunite following the defeat of the Demons of War and Tricks. Syliane also moves to Izuka town proper, under the castle gates.

Once you've defeated both the Demons of War and Tricks, here's what you'll need to do.

1. Talk to the Ice Cream Vendor and buy the Joy of Spring. Return to Izuka.
2. Give the Joy of Spring to Syliane and she'll reject it since she's allergic to berries.
3. Head back to Zenna and talk to the Vendor. Jordan will tell him the vendor needs to make a berry-less ice cream. Return to Izuka.
4. Talk to Syliane and she'll apologize for her illness.
5. Head back to Zenna AGAIN and buy the Joy of Summer.
6. Return to Izuka and give Syliane the Joy of Summer.
7. Go back to Zenna and talk to the Ice Cream Vendor. Buy the Joy of Spring if you feel like it.
8. Return to Izuka and talk to Syliane to FINALLY finish this quest.

For all that mess, Syliane gives you a Petal Pink Rain.

Earliest to start?: As soon as you leave Moondrop Woods and enter Izuka
Last chance: Before you abandon Jasmine for Melusine, OR before defeating Azutura, the Demon of Fear.
Other requirements: Only possible if you spared Jasmine's life

All you have to do is to spare Jasmine's life at the thieves' den. Talk to Hideo to start this quest, and Jasmine will vouch for Jordan. You'll get your reward, 666 coins.

The castle gets sealed off following the battle against the Demon of Fear.

Earliest to start?: As soon as you leave Moondrop Woods and enter Izuka
Other requirements: Talk to her twice to get this quest. You'll also need to recruit the Fox.

You need to recruit Melvut, a fox found in a haystack in Exelion. He'll only join if you managed to gather a menagerie of animals - at the very earliest you can have the Rooster, Cow, Bear, Wolf, Horse. You can't do this quest until you've defeated the Demon of Ego.

You need to go to the house to the right next door. Put the Fox in your party if you haven't already, then examine the vines to go down, and take the stairs to the basement. In the basement, keep going down until you can't go down any further, then go right and examine the hole. Return and speak to Reika to finish the quest.

I've made a video you can watch in case you're having trouble.

Earliest to start?: As soon as you leave Moondrop Woods and enter Izuka

Synaem eggs are rare drops from the Synaem enemy. The first chance you'll get is when you head to Wittaland while controlling Clea's party following the Pride and Luxury boss battles.

Synaem enemies have high speed and more often than not will flee from battle, so consider equipping speed-boosting equipment to your party members. You can also wait until Jordan and Clea have reunited following the battles against the Demons of War and Tricks to attempt this quest.

Once you have the Synaem Egg, return to Kyo and finish the quest.

Earliest to start?: As soon as you leave Moondrop Woods

The beast is found in the Tumulus of the Cave, a dungeon that only appears on the world map once you've triggered this quest.

It's not a particularly large dungeon, but I'd advise doing this AFTER defeating the Demon of Fear. If you want to, you can put this off til you've opened the final dungeon.

Earliest to start?: Before entering Zenna to talk to Melusine

Zaruzelas are spider-like enemies found in Zenna Cave, and they have a small chance of dropping a Zaruzela Skin. Simply farm them until you get the 6 skins, then bring them back to Doris. She'll give you a Fiber Skin as a reward.

Earliest to start?: Following the decision to choose Jasmine or Melusine
Other requirements: Talk to Kan twice to get this quest.

This quest can only be done after Clea and Jordan have reunited from fighting the Demons of War and Tricks.

At the Wittaland overworld map, from the town, head north and take the first western path you see. Keep to the western path and head north. Keep heading north until you see a large pine tree. Southwest of that pine tree is a hidden monastery, the Order of Ruu.

Head to the Order of Ruu and talk to Danae. She's located between a chair and pillar. Take her back to Zenna, and talk to Kan to finish this quest.

Earliest to start?: Before entering Zenna and talking with Melusine

There's a merchant in Suul, Tamto, who sells books. Buy the "How to Fish Everything" book, and return to Mambo.

You can talk to the horse vendor in either Zenna or Izuka for a quick ride to Suul.

Earliest to start?: Before entering Zenna and talking with Melusine
Other requirements: Talk to Burat twice to get this quest. You must also have recruited Alex into the party.

Although you can get this quest before entering Zenna and talking to Melusine, you need to recruit Alex to finish this quest.

After you've talked to Burat to obtain the quest, talk to Cynthia first. Put Alex in the main party, and talk to Burat after you've talked to Cynthia. Choose any of the options to get Alex to talk to Burat. When's Alex's done talking to Burat, you'll be outside the building. Go back in and talk to Cynthia to finish the quest.

Earliest to start?: Picking Melusine over Jasmine
Last chance: Before the Demon of Fear is defeated

You must have recruited/picked Melusine over Jasmine, and this quest must be done before you defeat the Demon of Fear.

The broken pillar is located south of where Jordan started out at the beginning of the game. See the accompanying screenshot to find the specific pillar Jordan is supposed to fix. Once he's fixed it, return to Kouhei. You'll be rewarded with a Monk's Charm.


If you're having a hard time finding the pillar, check the video below.

https://youtu.be/cY1ppRu5620

Earliest to start?: Following the decision to choose between Jasmine or Melusine
Other requirements: Must have picked Melusine, and requires Quest 17 to be completed.

This quest is only obtainable if you picked Melusine over Jasmine. Additionally, you need to have finished Quest 17 and recruited Barbara.

The hairy man is located in Zenna Cave, and you need to have Barbara in the active party. When the route splits in the second half of Zenna Cave, take the northern path to find a smoky campfire pit. There'll be a conversation, and a new path will open up. Take the path to find the hairy man.

I've made a video to show the way.


https://youtu.be/XCu_KJrXIM0

Earliest to start?: Following the decision to choose between Jasmine or Melusine
Other requirements: You must have recruited the Fox and the Raccoon into the party.

You need to recruit Melvut the fox and Mateo the raccoon. The fox is found in a haystack in Exelion and the raccoon can be found in Ezalbalaz. If you recruit the fox, then try to catch the dogs, the fox will comment he needs someone to bait the dogs. Once Jordan/Clea have reunited following the defeat of the Demons of War and Tricks, return to Zenna proper, and put both animals in the active party. Catch all four dogs and talk to Patrick to finish this quest.

Earliest to start?: After defeating the Demon of Fear.

This can only be done after defeating the Demon of Fear. You have to find the cat five times inside the Zenna hotel. Once you've found the cat five times, two things can happen: if Jasmine's in the party, the cat runs off. If Melusine's in the party, she hides the catgirl in Zenna Castle. Melusine and Jordan will learn a spell, Cat-A-Strophe. Clea and Shiro can also learn the spell, in fact, Clea should learn it if you're planning on getting the "Ancient Hero" achievement in Clea's scenario when she and Jordan split up.

Earliest to start?: After defeating the Demon of Fear

This can only be done after defeating the Demon of Fear. Jardel will challenge Jordan to a fight at Moondrop Woods. You'll find Jardel where Jordan started out at the beginning of the game. You'll fight Jardel, 1 Elephantine Bear, and 2 Grizzly Bears.

If you're having trouble finding Jardel, see the video below.

Earliest to start?: As soon as you reach Dela Vermelha
Other requirements: You must have recruited Alex into the party, you must have acquired the Thief's Acolyte, and you must have finished Quest 26

Although you need Alex to finish this quest, you do not need her to trigger this quest.

You also need to finish Quest 26 (fortunately, it's not time limited) to get Barbatas' Notes. Once you've done Quest 26, head to Zenna. Between Zenna and the Colyseum, there should be a new building, Ol' Slainthe Castle. (It blends into the mountains so well you might miss it the first time.)

Inside Ol' Slainthe Castle, there's an open space in the left side of the building. Enter it, and open the treasure chest. MEMORIZE THE NUMBER OF COINS IN THE CHEST. It's believed to be randomized every playthrough. Continue onwards and examine the gate. Input the number of coins found in the chest as the password to continue on. (If for some reason you forgot the password, there's a guard on the second floor named Dagmor who'll tell you how many years ago the castle was built. That also serves as the password.)

Cross the wooden bridge. See the screenshot below for the map to Horizon Island. You'll need the Thief's Acolyte to open the treasure chest containing the map. (The Thief's Acolyte can be obtained via a hidden treasure chest in Ezalbalaz Palace provided Jordan is at a high enough level, or by completing Quest 25.) Leave Ol' Slainthe Castle and head to Fort Zenna. Take the boat to Exelion. Talk to the sailor and choose "Horizon Island".

You'll be in the town of Perfection. Head south and leave.

When you're on the world map proper (it should say "Horizon Island") go left to find the town of Hope. Talk to Nagusham until he reveals the secret of Horizon's pure water. Go into the house, and check the hole to enter the basement. Have Jordan examine the pool by the waterfall and he'll drink some of it. Alex will bottle a jar of water with her.

Return to Dela Vermelha and Alex will automatically cure the chickens with the Horizon water.

Earliest to start?: As soon as you reach Dela Vermelha

The quest giver is located in the Inn's first floor and he's the only man in the inn aside from the innkeeper.

Check the forest between Exelion and Dela Vermelha, to the right. Examine the campfire and you'll find Barbara and her tiger, Pacha. Both of them will force Jordan into a fight. You can use Jordan's "Horror of Memories" to paralyze/confuse them. If you gave Teksab the Rope of Pain, there's a high chance he'll be able to paralyze Barbara and Pacha. They'll join Jordan's party upon defeat. Go back and report to Dander to complete the quest.

NOTE: If Barbara's in the active party, remove her first before reporting back to Dander.

Earliest to start?: As soon as you reach Dela Vermelha
Other requirements: Speak to Dahlia twice to get this quest.

Examine the wall scroll on the 5th floor of the Hotel of Ascension. Return to Dahlia and give her the fish. She'll reward the party with a choice between a Kudame Brightness/Darkness/Equilibrium, a Helmet-type equipment that cannot be removed once equipped, so think carefully about who you want to give it to.

Check the video if you're having trouble finding the fish. (NOTE: the video has some visual/audio sync issues and while I wouldn't upload a video with such a technical error, I really loathe this game enough as it is and in all honesty this guide and the main Achievements guide were only made to spare others the suffering.)


https://youtu.be/j5cmIBEPaIs

Earliest to start?: When you leave Dela Vermelha, on your way to the Hotel of Ascension
Other prerequsites: Must have obtained the Thief's Acolyte

Omalu's mother is being held prisoner in a secret basement of the thieves' den, all the way back at Moondrop Woods. You'll need to have the Thief's Acolyte (acquired from Q25 or a chest in Ezalbalaz Palace with Jordan having either a Lock Breaker OR a high enough Intelligence stat) before you can free the mother.

Talk to the woman, and return to Omalu in M'dale to finish this quest.

Earliest to start?: After defeating the Demon of Ego, before leaving Zander for the Majestic Hotel
Last chance: Before leaving Zander for the Majestic Hotel
Other requirements: Must have recruited Alex into the party

You need to recruit Alex to trigger this quest. Once Alex's part of the party (she doesn't need to be part of the active group), talk to the Innkeeper to learn two people have wandered into the Serpentine Woods. The two people can be found behind a large stone tablet. You need to finish this quest before returning to Izuka.

If you're having trouble finding the tourists, check the video.

Earliest to start?: During Clea's scenario of going after the Demon of War

You can only do this quest proper once Clea and Jordan's parties have reunited. Head to the temple in Greenland, have Jordan in the active party, and talk to the monk standing near the green flame torch, not far from the priest. Go to the right side of the entrance hall, and examine a lone green flame torch, seen in the accompanying screenshot. Jordan will take it. Return to Helga to finish the quest.

Earliest to start?: During Clea's scenario of going after the Demon of War
Last chance: Before defeating the Demon of War

You'll find Stella in the northeast forest of the island, Solitude Woods. Once you've found/talked to Stella, return and report to Crystal. She'll give you a Magic Trinket and move to the inn/equipment shop in Kutika. If you talk to Crystal at the Kutikca inn/shop, she gives Clea 3 Magic Trinkets.

You HAVE to finish this quest while you're controlling Clea and company otherwise you won't be able to do Quest 23.

Earliest to start?: During Jordan's scenario of pursuing the Demon of Tricks
Other requirements: Must have completed Quest 22

You need to have done Quest 22 during Clea's scenario of pursuing the Demon of War, and if you forgot to talk to Crystal after finding Stella, you can't do this quest.

Following Jordan and Clea's reunification after the defeat of the Demons of War and Tricks, head to Solitude Woods and talk to Stella. Ask her to teleport you to Greenland. Head west and enter the Temple of Shakah.

If you've cleared Quest 22, Crystal can be found in the 2nd floor. Talk to her to get a Monk's Holy Writings.

Leave the temple, and re-enter it. Head to the left side and Crystal will be below the stairs, standing between the bolts of fabric and a large mortar and pestle. Talk to her, and tell her, "Paint the walls."

Head back to the entrance hall and go to where Crystal is. Behind her are three pots. Examine the bottom-left pot and Jordan will take it.

Go to Ezalbalaz and talk to Ibarakabe. He'll take the paint pot and head to the Throne Room. Speak to Ibarakabe there to finish this quest.

Earliest to start?: During Jordan's scenario of going after the Demon of Tricks

You can only do this quest proper once Jordan and Clea have reunited following the defeat of the Demons of War and Tricks.

The fugitive is located in Lone Cave, the cave that connects the Recife and Half-Moon continents. The easiest way to find him is to enter from the Izuka side - head right, take the first southern path, go west, and head south. Talk to the man twice and take him back to Ezalbalaz. You'll get a Salt of Sabazaru accessory as your reward.

I've made a video to show how to complete this quest in case you're having trouble.


https://youtu.be/o_6Jl3HilCw

Earliest to start?: During Jordan's scenario of going after the Demon of Tricks

The pendant is found in a pile of ash at the Arxisian Fortress. (See the screenshot for reference.) Return the pendant to Jordana and she'll give the party the Thief's Acolyte.

Earliest to start?: During Jordan's scenario of going after the Demon of Tricks

This quest isn't the most time-consuming, but it's the worst.

What you have to do is to go to the next map of the Solace Cave from the northern path, run clockwise, head at the first southern path, then backtrack, and go into the nothern-most notch to find the kid. Once you've found the kid, the father/quest giver relocates to Ivy Cave, which is near the town of Ezalbalaz.

If that sounds confusing, here's a video instead.

Earliest to start?: After Jordan/Clea have reunited following the defeat of the Demons of War and Tricks

If you kept Jasmine over Melusine, you won't have access to this quest since you'll be permanently barred from Melusine's Castle.

The assassin, called The Chopper, is found in the castle chapel, hiding behind the left curtain. (See screenshot for reference.) The Chopper has very high speed, so you'll need to be very high-leveled and well-equipped to tackle this bonus boss.

If you did Quest 26 and opened access to Ol' Slainthe Castle, one of the weapons found is a sword called Mortel, which has a small chance to instantly KO an enemy. Surprisingly, The Chopper is not immune to OHKOs, so if you're having serious trouble with this quest, do Quest 26, then go raid Ol' Slainthe Castle for the Mortel. Either Barbara or Melusine can equip the Mortel, so put either one in the main group, and whoever has the Mortel should also have speed-boosting equipment.

Earliest to start?: On the way to the final dungeon

The present is hidden in a pile of golden sand within Sino Cave. I've made a video below the screenshots in case some assistance is needed in finding the item.

You'll get a Big Titan Bone as your reward.
