After you defeat Zoma in his Castle and escape to the Cave north of Ludatorm, exit the Cave and you will hear a rumble which tells you the hole to the World above closed: now you can only cast Return to the five towns in Alefgard. Not only this: with the death of Zoma the light returned to the dark Alefgard. Return to Ludatorm and get hailed as a hero there. Talk with the King and he will tell you what you already knew: The Hole to the World above has closed and the light has returned thanks to Zoma's Death. Then he gives you the title of the hero, Erdrick (Loto in the GBC version). The credits will then roll over the screen until the text "To be continued in Dragon Quest I-II" appears.
Reset the game and try to reload your savestate: you will see the hero title "Loto" appears next to your name. Now that you are given the title, you can go to the Sky World, that is the bonus dungeon. In the Sky World you can obtain more treasures, but also meet new and stronger monsters. The last step in the Sky World is the wish filled by God Dragon/Divinegon once you defeat him.
The Sky World dungeon[edit | edit source]
Access the Sky World[edit | edit source]
Return to Dragon Queen Castle to the place where you found the Small Medal. Go in the sunlight and all around you will get distorted and you will appear on a small Heaven isle with a cave which is the Bonus Dungeon.
The bonus dungeon[edit | edit source]
In the Bonus Dungeon new monsters never seen before will appears along with some known monsters. Dark Troll, Evil Crab, Ramia, Gate Guard, DemonSword, Baramevil, Mtl Wyvern, Devil Wiz are new monsters. Baramevil is the only one who drops a Mystic Nut, but if you want to hoard seeds and maximize your attributes, then you'd be better off going for Wisdom Seeds instead. King Hydra is also a common Monster in this dungeon.
When you enter it you will probably get the feeling you know this dungeon, and you're right: this part is from Necrogond Cave, as well as every other level of the Bonus Dungeon is taken from other places. You will recognize a lot of places as you walk through the dungeon.
Anyway, go north then west for a chest which contains a Mimic. You may as well ignore it and go east until you find a path going north. There is another chest with a 
STRseed / 
Strength Seed inside. Grab it then go east, north and then west all the way. The chest at the dead end contains a 
Bounce 
/ 
Staff of Reflection. Now go east to the stairs to the next level.
Just like in the Necrogond Cave you need to find the right way to the next stairs below, but there are no treasures on this level. The next level is from Orochi Cave. Just like there, a treasure chest can be found at the same place. It holds a unique item that you thought was lost it in the volcano: it's the 
Gaia 
/ 
Gaia Sword!
A level deeper you find yourself in the pyramid, where two different stairs exist. Take the right stairs to a room where a priest lives. Under the cross is a MysticNut / Mystic Nut hidden. Go back up and go to the treasure chest southwest: it has a 
TinyMedal / 
Small Medal. Now take the left stairs downstairs to the next level.
This one has a HP/MP recover spot just like the Dream Cave near Noaniels. This is an ideal spot to train yourself to higher levels, as the boss is quite tough. Go west then north ignoring the west path for the moment. At the end go get 
Sorrow 
/ 
Sorrow Shield and TinyMedal / Small Medal from the two chests. Now go back and take the west path.
In the next level search two treasures with the help of the "Seek Out" spell. You will find STRseed / Strength Seed and LifeAcorn / Life Nut near the statues. This is the bottom, now you start climbing stairs up. In the Samanosa Jail there are also two treasures, one in the pot and the other right to the corpse; they are a TinyMedal / Small Medal and a 
Hero 
/ 
Hero Guide.
You will pop up in an arena. You've only been outside of the battle arenas to bet on monsters, but now you're battling a monster in the arena yourself. The audience outside the arena tells you good luck while the monster, a Baramevil, asks you, why you so weak are. You can battle him if you want, or ignore and walk around him and continue on. There is a 
Token / 
Pachisi Ticket hidden in the ground near the monster. After the monster, there is a small and monster-free floor from the lighthouse. Going down the stairs brings you finally to Zenithia.
Zenithia[edit | edit source]
After reaching Zenithia, add it to the Return-List so you don't need to walk through the entire dungeon again. The King welcomes you to Zenithia, introduces himself as King Zenith, and tells you that the God Dragon/Divinegon will grant any wish you choose. The Bard in the right room will give you three riddles to solve. The Bard is in the top right corner. The staircase at the bottom leads to the Old Man.
Once you're done in Zenithia, go downstairs and talk with the old man. He will ask you if you want to meet the God Dragon/Divinegon and offer you medicine from the boiler. Check both pots for a TinyMedal / Small Medal and a 
Flee 
/ 
Flee Ring.
Riddle #1[edit | edit source]
A town lies in ruins, and something shines beneath the cross.
This can only mean Tedanki, so jump off the Castle, go to Tedanki, and search there during the day under the Cross for a 
Beast 
/ 
Beast Claw. It's stronger than the Dragon Claw, but only Wizard and Thief classes can use it.
Riddle #2[edit | edit source]
A town, surrounded by darkness. Something sleeps in the flowers...
There are only five towns in Alefgard and though others towns also have flowers, the correct town is Mercado. Go in the middle building and search under the second flower from the top for a 
Dark 
/ 
Dark Outfit.
Riddle #3[edit | edit source]
Find the one who looks at the stars without ever glancing down.
This can only be a telescope: where can you find one? Of course in Luzami! So go there and search right besides the man behind the telescope for a 
SageRock / 
Sage's Stone. After you return to the Bard, he will conclude that you are smart and he will give you some info regarding Small Medals, such as how many are left to be found.
Divinegon Tower[edit | edit source]
Exit the room and you will find yourself at the bottom from a tower you've never seen before. At the top of this tower lives the legendary Dragon. Climb up the ladder and go left inside to find two treasure chests containing a TinyMedal / Small Medal and a 
Ruby / Ruby Ring. Walk back outside, go right and inside the other door.
Walk through the room and go upstairs. On the second floor you have to walk over the ropes twice to reach the exit, so beware not to fall down or you have to do it all over again.
Exit the tower, go left, climb the stairs and re-enter.
Go left and get the TinyMedal / Small Medal: it's the last one and with this you should have all the 110 small medals you can find in the game. Go up and ignore the north stairs, it only leads to a empty room, and go down the other stairs.
Now go north to get 
LUCKShoes / 
Lucky Shoes from the chest. Go back south and outside. In the chest outside is the strongest weapon, a 
Wreck 
/ 
Wrecking Flail, that can attack every enemy too. Go back inside and go north to the stairs.
You are now on the last floor. There is nothing important to grab in this big room, so just go to the stairs which bring you to the roof, where God Dragon/Divinegon awaits you.
God Dragon/Divinegon/Xenlon[edit | edit source]
If you chose your class changes wisely, it is possible to beat Divinegon at around level 40. The problem on this boss is the time: You start off only needing to beat her in 35 Turns to get your first wish. However, your second wish reduces that to 25 Turns, and every wish after that reduces that to 15 Turns.
She has many devastating spells & techniques that hit your party for massive damage, and a bite attack that can do over 200 Damage to one target. Not only that, she can automatically put someone to sleep any time she feels like it, with no chance of resisting it. Finally, she can remove all your buffs, just as Zoma did.
Unfortunately for you, she also has 7300 HP, so you need to be very aggressive in spite of all of that. You need to do great amounts of damage each turn—enough that you'll come out on top even if you get bad luck with her icy pulse, Lullab-Eyes, and other attacks.
The only three practical ways of dealing that kind of damage are as follows. Note that these all assume the Hero is wearing the Bolero robe to cast HealUsAll more often:
- Critical hits from Fighters with their attack boosted as high as possible
- Blazemost spells (with maybe some Thordains thrown in)
- A trick involving Sages with Falcon Swords equipped Transforming into a Hero with his attack boosted as high as possible
The first method is only practical at exorbitantly high levels, as those are what determine how likely a Fighter is to score critical hits. Plus, their equipment selection is poor, so Light Dresses from a hard-to-reach shop on the 5th Pachisi Track is the only way to get them the kind of breath & magic resistance you desire.
The second method is possible with three party members who've all become Level 36 Mages at some point or another. Such a party could slay Divinegon in 14 Turns, assuming good luck (as-in no more than 4 Blazemosts wasted due to bad RNG)—possibly 13 Turns if the Hero manages to sneak in two Thordains between using HealUsAll & the Sage's Stone. This may be the overall fastest way of completing the SNES version, as Mages require relatively little experience to get to Level 36 (compared to the Sages getting to Level 37), and also have Poison Needles, PanicAll, and powerful offensive spells to help with Rimuldar grinding.
Then there's the method listed here. It requires slightly more grinding than the strategy listed above, but it's strong enough to slay Divinegon in 11 Turns with optimal luck. Max out the Hero's Attack via the Valiant personality, all the game's Strength Seeds (be sure to scum +3s from them all), along with the Hero Ring & Wreck Flail. That will give them 405 Attack—the highest possible before slaying Divinegon. Then, once the Sages Transform into the Hero, they'll copy over his stats & spells while still keeping their Falcon Swords. That gives you two characters attacking twice off of 405 Attack. With Bikill, this allows both sages to do ~360 Damage every time they attack.
Of course, Divinegon will be hammering you the entire battle, so you'll want both Sage's Stones on your Hero & Bikill user. And, while it isn't totally necessary, the Bolero robe is greatly useful to have in the Hero's inventory. It cuts MP costs in half, so it's good for them to switch to any time they cast HealUsAll. It is thus recommendedFinally, you'll want all your magic & armor to resist magic & breath attacks (with greater priority on breath).
With all this, you should be able to defeat Divinegon in 15 Turns or less, so long as she doesn't waste 5 Turns or more with her worst attacks. Then for defeating her, you will receive 50,000 experience and sometimes she drops a Strength Seed. If you defeat her within the time limit, then she will grant you a wish, but only one. So choose wisely which one you want:
- Pachisi Track in the well of Jipang
- Revive Father Ortega
- Naughty Book
The Naughty Book changes your Personality to Lewd (Man)/Sexy (Woman). Reviving your father brings your father back to life and he will be in Aliahan by the side of your mother. Other than that nothing special happens. The best thing is obviously the Pachisi Track which will now be in the well in Jipang/Zipangu, with the Bolero at the end.
Two more wishes are available in the GBC version:
- Rare Medals, to be asked three times in order to get all three sets
- Ice Cave, the second bonus dungeon. The entrance to the Ice Cave will appear in Leiamland, in the exact spot where Ramia's egg was.
