How to defeat Hargon / Malroth in Dragon Quest II
Dragon Quest II: Defeating Hargon/Malroth

Dragon Quest II’s adventure culminates in an epic onslaught of demons leading up to the fated encounter with Hargon himself, as well as the much more menacing being he calls upon, Malroth.

Some Quick Tips on how to prepare for the final gauntlet of enemies:

  • Endgame Builds: The equipment you carry into Hargon’s Castle is essential to keep track of.
  • Magic Management: Conserving MP and choosing when to Heal vs. when to Kasap/Kabuff is critical for this boss rush.
  • War of Attrition: The final boss will test your ability to be patient and tactical quite a bit.

Final Loadouts

Being able to heal and save for free here is an act of true generosity from this game

Once you’ve escaped the Cave to Rendarak and made it to the extremely convenient Shrine where you can Save and fully heal your party’s HP/MP for free, you’ll also have it registered as the final Zoom location in the game. 

Now is the opportune time to do your final grinding and managing of your party’s loadout. 

For the final dungeon and surrounding area, you can get through most scrapes relatively unharmed with your Hero at level 39, your Prince at level 36 and your Princess at level 30. If you have the time, patience and dedication to grind on some of the difficult-yet-EXP-yielding enemies in Rendarak, however, you can get through things more comfortably with your party in the low to mid 40s.

Where things make a larger difference is in your final loadout. There are more expensive and higher bonus-granting items out there to buy as opposed to what’s listed here, but the slowness with which you gain Gold and how unnecessary those items are makes these builds the most reliable:

Hero:

  • Weapon: Thunderbolt Blade
  • Armour: Erdrick’s Armour
  • Shield: Erdrick’s Shield
  • Helmet: Erdrick’s Helm
  • Accessory: Banishing Bell
  • Extra: Power Shield

Prince: 

  • Weapon: Aurora Blade
  • Armour: Magic Armour
  • Shield: Power Shield
  • Accessory: Banishing Bell

Princess:

  • Weapon: Lightning Staff
  • Armour: Flowing Dress
  • Helmet: Mad Cap
  • Accessory: Banishing Bell
  • Extra: Power Shield

The importance of having Power Shields for your entire party cannot be understated at this point in the game, as the ability for characters in battle to cast Midheal on themself at no MP cost is, quite literally, going to be a lifesaver more times than you’ll be able to count. 

The only real consumables you’ll be wanting are an Yggdrasil Leaf (held by the Hero since he’s the only party member without Kazing), found on an island near Burrowell and the Fire Shrine, and any Prayer Rings you’ve been holding onto for your Prince and Princess to use in a pinch.

Once you’ve got everything you need and you’re at a comfortable level, it’s finally time to storm the castle gates.

Crashing the Castle

The enemies in Hargon’s Castle are largely the same as the ones in the surrounding region of Rendarak. They’re pretty strong, but if you’re well equipped and you’ve been grinding, you can take them down and Power Shield frequently to avoid having to spend much HP. 

The main enemy you’ll want to keep an eye on during random encounters in the dungeon is Wrecktor, who can cast Kazing to fully revive a slain monster. If you’re in a battle with a Wrecktor, prioritize taking it out ASAP so it doesn’t prolong the fight.

Here’s a table detailing the enemies you’ll run into around and inside the castle:

Starting from the Rendarak Shrine, head north, turning west and south until you successfully make it around the landmass and north up to the stronghold of Hargon. 

Brace yourself and enter.

This place looks pretty familiar

You can unbrace yourself, however, as you appear to be now standing in a normal town. Not any town, mind you: this is, at first glance, a copy of Midenhall. The residents, however, seem to be a big fan of Hargon, and attempting to talk to the Hero’s “father” will throw you into a battle with several Batmandrills, so all is not well. 

Note: Despite the spooky scenario, the inn at the entrance to this phony Midenhall is, in fact, fully functional. If you took some damage/spent some MP on your way here from the Shrine, go ahead and spend the measly 9 gold to rest up before you continue.

From the first floor, head up to the throne. Cast Safe Passage to avoid the damaging tiles, then look for the exclamation point (which sound be a few squares west and north of the throne).

Avoiding more damage from tiles with Safe Passage, make your way north to the back chamber with the cross. Stand in the center tile with a different color, and use the False Idol to be teleported to the next floor.

On the fourth floor, following the corridor going east and south to approach the stairs.

Be warned, however, that you will be thrown into a boss fight before you can make it up the stairs.

Attacking Atlas

Atlas | Dragon Quest II
Atlas
225 HP – 0 MP – Attacks Twice – 3300 EXP
For the first of many bosses you’ll be fighting here in Dragon Quest II’s eleventh hour, Atlas is by far the easiest. Have your Prince and Princess casting Kabuff and Kasap on the first turn, then wail on him the subsequent turns with your Hero and Prince. Atlas can put a dent in people with his two attacks, but between your Princess being available to heal (or attempt to instantly kill him with Hocus Pocus) and everyone’s Power Shields, you shouldn’t be in this fight too long. 

Once you’ve taken him out, heal your party up. Climb the stairs past where he ambushed you. 

Note: The next boss can, with bad enough RNG, instantly wipe out your party with one spell, so making a Quick Save here is highly encouraged.

On the fifth floor, you’ll see several small rooms. Make a beeline for the northwesternmost room, but be ready for another boss fight as you approach.

Powering Through Pazuzu

Pazuzu | Dragon Quest II
Pazuzu
225 HP – 50 MP – Snooze, Fizzle, Sizzle, Fullheal, Thwack, Kaboom, Kamikazee – 4400 EXP
Pazuzu has quite the arsenal of spells at his disposal, but he’s not too bad, all things considered. Have your Princess Kasap him, then go to town on him with your Hero and Prince. Once his HP is low, the fight will become a coin toss as to whether he’ll decide to Kamikazee. If you’re feeling feisty, you can speed things up by casting Kaboom or Hocus Pocus (which has a ¼ chance to kill him or cause him to flee, the latter of which will cause you to not gain any EXP from the fight. Otherwise, with some patience and willingness to reload if you end up on the wrong side of Kamikazee, you should be through with him in a few turns.

After Pazuzu is vanquished, heal up your party once more and consider updating your Quick Save slot, then proceed up the stairs in the northwest corner of the room.

On the sixth floor, head east across the bridge and as you approach the pillars in front of the stairs, you’ll be thrown into the last of the pre-Hargon boss battles.

The Battle with Belial

Belial | Dragon Quest II
Belial
325 HP – 240 MP – Attacks Twice, Torrent of Flames, Kaboom, Fulheal – 6270 EXP
Belial has a few things that make him a bit tougher than Atlas or Pazuzu, but not by much. He’s immune to Kasap, but strangely enough can be instantly killed by Hocus Pocus (with some luck).  He might drag the fight out by spamming Fullheal, but if you keep your Hero and Prince on the offensive with your Princess supporting them and he’ll go down. 

You know the drill by this point. Heal up, Quick Save, and head up your final flight of stairs.

Hargon really doesn’t want to have any visitors | Dragon Quest II
Hargon really doesn’t want to have any visitors

Holy damaging tiles! Cast Sacred protection and make your way west and north into Hargon’s chamber. After a little bit of banter with the Dark Priest himself (it doesn’t matter if you say Yes or No to him, it’s just flavor text) you’ll be thrown into what you might assume is the final battle. 

There is a much more difficult boss coming up, however, so don’t burn your valuable resources just yet.

Defeating Hargon 

Hargon | Dragon Quest II
Hargon
450 HP – ??? MP – Attacks Twice, Torrent of Flames, Sickly-Sweet Breath, Kaboom, Midheal 
Hargon isn’t the toughest enemy (that honor goes to the upcoming fight), but he has a pretty strong array of moves. 
He can’t Fullheal, unlike Pazuzu and Belial, but he is immune to both Kasap and Hocus Pocus. Additionally, he seems to have infinite MP, but without much HP to back it up, that shouldn’t really be a problem. 
There isn’t too much to say about this fight, just keep at it and know when to Power Shield.
Hargon’s dialogue | Dragon Quest II

Hargon goes down for the count, but not without calling upon his dark master, Malroth, as he crumbles. 

Warning: The moment you attempt to leave Hargon’s chamber, you will be thrown into the most intense and difficult fight of the game, the actual final boss. As soon as Hargon’s dialogue is over and you have control, open your menu to Heal, pop any Prayer Rings you’ve been holding onto, and Quick Save one final time.

The whole place erupts in flames | Dragon Quest II

You can attempt to make a break for it, but it’s too late. The whole place erupts in flames, the ground crumbles, and Malroth descends upon you.

The Might of Malroth

Malroth | Dragon Quest II
Malroth
1750 HP – ??? MP –  Attacks Twice (sometimes), Kasap, Kabuff, Blistering Flames
No more fakeouts, this is the final boss, and the game isn’t going to pull any punches. Malroth’s HP is staggering, to say the least, but fortunately he can’t heal himself. He’s immune to Hocus Pocus, but thankfully can be affected by Kasap, which is good because you’re going to need it. 
As soon as the fight starts, get your Kabuff and Kasap cast while your Hero is maintaining the offensive line. You’ll need all the defensive bonuses you can muster, so always Kabuff when Malroth uses Kasap, and always Kasap when Malroth uses Kabuff.
Aside from just the necessary boost to your attacks as you whittle through his massive HP reserve, if you’re lucky you can get Malroth to spend most of his turns using Kasap/Kabuff as opposed to his devastating attacks or Blistering Flames. 
It may be tempting to unload all of the Princess’ MP into throwing Kaboom after Kaboom at Malroth, but unless you’re severely overleveled, the best strategy here is to play it safe with lots of Defending, Power Shielding, and the aforementioned Kabuff/Kasap maneuvers. 
Kazing is going to get a lot of play in this fight as Malroth will be knocking party members out left and right. You’re almost certainly going to be using your Yggdrasil Leaf as well, which is why it’s best if your Hero holds onto it so you have a contingency plan if both your casters go down.
In summary, heal frequently, keep your defense up and his down, and don’t get too cocky.

With some luck and determination (and possibly a few loaded quick saves), the party will vanquish Malroth, ridding the world of his evil once and for all. You’ll hear a disembodied voice (of Erdrick?) and that’s that. 

Head back to Midenhall (the real Midenhall, not the fake one), go speak to the King and enjoy the end credits.

Congratulations, you’ve finished Dragon Quest II: Luminaries of the Legendary Line!
