After saving the mermaids from their tormentors in the Mermaid Sanctuary, you’ll be rewarded with the Magic Key, which will open all sorts of doors and chests - provided that they’re blue! By now you’ve explored quite a lot and the task of backtracking to claim old treasures can be quite daunting. This page will cover all the magical chests and doors in past areas you can now open, removing a lot of the tedium and guess-work from this endeavor in Dragon Quest 2: HD-2D Remake!

Page Breakdown¶

All Magic Key Treasures¶

Below you’ll find a list of all the treasures you can obtain now that you have the Magic Key. This will not include areas further along in the story, as… well, you don’t really need to do any cleanup to find those - now that you have the Magic Key, you can just get them the first time you explore! So areas like the Den of Iniquity and Slewse won’t be covered. That said, new story events and treasures that can be found in old areas will be, as is the case for the Deserted Village and Moonahan. We’ll generally just go down the list of areas as they appear in the Zoom menu, with an outlier to start things out…

Faerie Palace¶

You’ll need to return here next for story reasons, so we might as well start our Magic Key cleanup here. Talk to the Over-Seer - who implores you to find the [remaining Sigils] (something we can do now that we have the Magic Key), then the Record-Keeper, who asks you to recover seven [Living Memories] scattered throughout the world (something we cannot complete now - but we can make a bit of progress, if you don’t mind some underwater exploration).

After being pestered by the faeries, head down to Faerie Palace - 1F and search the western edge of the level to find two magic chests you can open to obtain a Prayer Ring and a Dog Suit. Another Magic Chest, near the item merchant to the east, contains a Tempest Shield.

Midenhall¶

The big cache of treasures here are in a room in the southeastern corner of Midenhall Castle - 1F, behind a blue door. With the Magic Key you can open this door and plunder almost all the chests inside, save for one which requires the [Ultimate Key] to open. Get this loot, then head down to B1 and prepare for a fight. When you’re ready, go through the northwesternmost cell door and talk to the man within, only to find yourself facing a Wrecktor - a normal enemy, albeit one normally found late-game. Defeat it and you’ll obtain a Lightning Staff, and you can search the floor behind the Wrecktor to find a Seed of Magic.

Cannock¶

What Cannock doesn’t have in quantity, it makes up for in quality. Loot the blue chest in the middle of Cannock Castle to obtain Erdrick’s Shield, which has high Defence and reduces damage from all spells and breath attacks. It can be equipped by any character. Nice. You can also loot a Rabbit’s Tail, Garter and Rabbit Ears from the large room upstairs. Naughty monarchs!

Deserted Village - Den of Thieves¶

Travel to this rather unassuming area southeast of Moonahan and you’ll get some scenes suggesting that this place is haunted. Head to a hut along the western edge of the village and after another scene, go through a blue door to enter the aforementioned hut and search south of the stairs to find some Tanglewebs. Head downstairs to reach the Den of Thieves and continue east to trigger a scene, after which you’ll need to defeat the Wild Hog, Pillager and Surgical Spirit - a trio of minibosses. When vanquished they’ll drop Harmour and after the fight you’ll get the Misplaced Key, which will open up a new area in Moonahan.

Before running off, however, loot can loot the area to find a Thief’s Turban in a pot to the west, a Steal Sickle Scroll in a chest to the northwest, the Padfoot Scroll in a barrel to the northeast, and a Stealth Suit in a barrel to the east.

Moonahan¶

Return to Moonahan and enter the building northwest of the Tombola Stall and go downstairs to find that the passage leading to the island to the west is now navigable. Head west until you find a gate to the north and approach it for a scene. Sure enough, with the Misplaced Key this gate will open. Head through the gate and search the northern end of the circular stone platform beyond to find a Seed of Magic, then exit to the northeast to encounter the Sinister Minister. Defeat the boss and after some scenes you’ll get the Water Sigil.

Moonbrooke¶

Only one treasure here, head to Moonbrooke Castle - B1 and loot the middle (blue) chest in the center of the level.

Shrine of Flames¶

Follow the path uphill along the eastern edge of the area and pass two pairs of braziers. At the third pair, veer west to find a blue chest, which will yield this area’s lone new item - a Flame Shield.

Tantegel¶

There are a few treasures in this area. First head to the inn and go through the blue door (the westernmost one) and loot a sack on the wall to obtain a Mini Medal. Next enter Tantegel Castle - 1F and work your way to the eastern edge of the level to find a blue door you can now open. Pass through it and to the south you’ll find an electrified floor. Cast Safe Passage to cross without taking damage and loot a chest to the right (east) to gain 2,000 gold, then plunder some barrels to the south to find an Angel Bell and a Seed of Life.

Now head to the western edge of the level and go upstairs to reach Tantegel Castle - 2F, which is rotten with rooms you can now plunder. In the northwestern room are 4x Tombola Tickets in a dresser along the northern wall, some Fishnet Stockings in a red chest along the western wall, and a Seed of Luck in a pot by the bath tub. In the northeastern room you’ll find some Enchanted Robes in a red chest

Finally, exit the castle via either of its two northern doors to reach Tantegel Castle - Gardens and head down the stairs in the pavilion along the southeastern corner of the area to reach Tantegel Castle - B1. Go to the southern end of this level and enter the door to the north and open a chest along the northern end of the room to score a Banishing Bell and plunder a pot to the east to find 3x Tombola Tickets.

Galenholm¶

Three treasures in Galenholm. First hit the inn to find some Rabbit Ears in a blue chest, then go into the large dockyard building to the north and from the entrance head west to find a room with a blue door. With the Magic Key you can now get inside - loot the wardrobe and dresser in the northwestern corner to find a Cat Suit and 7x Tombola Tickets.

Kol¶

Only one item awaits you in Kol - enter the westernmost house and you’ll find a blue chest along the northern wall, which contains Orochi’s Sword, a weapon with decent stats (likely an upgrade for somebody at this point in the game) that can be used in combat to lower a group of enemies’ defence.

Shrine of Rain¶

Another one-item stop, head to the southeastern corner of the Shrine of Rain - 1F to find a blue chest in the middle of the circular room, wherein you’ll find a Spirit Bracer.

Quagmire Cave¶

Actually a fair bit to find here. Head to the southeastern corner of Quagmire Cave - B1 to find a blue door, beyond which lies the stairs leading down to B2. Since you couldn’t access B2 before acquiring the Magic Key, everything you find down here is new. In the southeastern corner of this level you’ll find a blue chest containing a Metal Slime Helm, which not only has excellent defense, but “reduces the amount of damage taken from all kinds of spells and breath attacks when equipped”. Alas, only the boys can wear it, but it’ll certainly find a home atop somebody’s head. Next head to the northern edge of the map to find a red chest containing the Dragon Slash Scroll. There’s also a green chest in the middle of the level you can’t open without the [Ultimate Key], but even with only two treasures, this has been a fairly lucrative trip!

We’re not done yet, however. Find the stairs up on the western edge of the level to surface along the eastern edge of B1, which is otherwise inaccessible. From the stairs go east, south and west to find a red chest containing a set of Silver Claws. That’s the last bit of look you can get here, so Zoom away to your next destination.

Rimuldar¶

Another quick stop, enter the inn along the southeastern edge of town via the (blue) southern door to find a blue chest containing a Snub Scroll.

Craggy Cave¶

Head to the northeastern edge of the level to find a large room, inside of which is a blue chest along the northern edge of the room. Loot it to score a Stealth Suit. There are two green chests on B2, you can’t open them until you get the Ultimate Key.

Damdara¶

Enter the mostly intact building along the center-west of the map and loot a blue chest inside to find an Agility Gilet.

Cantlin¶

With the Magic Key you can enter the building along the northeastern edge of the map. Do so, go upstairs, and loot a blue chest along the northern edge of the room to score 2,400 gold.

Dragonlord’s Castle¶

Another day, another slog through the Dragonlord’s Castle! First descend down to B2 and from the stairs work your way through the tunnels until you find yourself going north along the western end of the level, then search a long, dead-end tunnel running east to find a blue chest containing a Wasteband, cursed equipment that you should not equip. Next continue to the southeastern edge of the level and loot another blue chest with a much more valuable prize inside - Metal Slime Armour. Like the Metal Slime Helm earlier, this armor has a high defence stat and reduces damage from spells and breath attacks.

Finally, continue down to B6 and work your way to the treasure room on the eastern edge of the western half of the level and loot the sole blue chest to obtain a MIni Medal. Can never have too many Mini Medals!

Beran¶

Enter the inn on the western edge of town and go through the blue door to the southeast and loot a wardrobe to find 7x Tombola Tickets.

Shrine North of Beran¶

Enter the building to find three chests. Loot the northwestern (blue) chest to obtain a Happy Hat, which recovers MP with every step you take!

Burrowell¶

Enter the center-east building and head north to find two cells. By this point in the game, the easternmost cell should house the Black Sanguini, and you may trigger a scene if you haven’t returned here since defeating the Succubeast. Once the chatter, if any, is done, enter the cell and exit to the east to reach a side chamber. Search a pot to the east to obtain 2x Tombola Tickets.

Secret Area Southeast of Burrowell¶

Sail southeast from Burrowell to find a rocky island. Land on it and search the western edge of the island to find a blue chest, which contains a Pirate King’s Pendant.

Secret Area East of Burrowell¶

On an island east of Burrowell, northwest of Yggdrasil’s Arbour, search a forest for a rock that marks a secret area, inside of which is a blue chest containing a Rabbit Suit.

That should be it for all the Magic Key cleanup! There are undoubtedly more blue doors and chests you can find under the sea, in the Slewse region, and in areas further beyond, but you should be able to get them on your first pass through, comfortable in the knowledge that you’re not missing anything!

Secret Area Between Moonbrooke and Rendarak¶

Sandwiched between some mountains south of the Pillars of the Wind and another range of mountains surrounding Rendarak to the south is a strip of desert. On the western edge of this desert is a secret area, and while technically you can reach this area as soon as you get the ship from Rippleport, there’s no sense in braving the powerful monsters - both in the sea and on land - that await you enroute to this secret area until you have at least the Magic Key. If you can make it through this gauntlet of monsters, open the blue chest to obtain a Metal Slime Sword.
