In Baldur’s Gate 3, Balduran’s Giantslayer is a must-have Legendary Greatsword you can acquire in Act 3 – this short Guide explains everything you need to know about Balduran’s Giantslayer in BG3.
Balduran’s Giantslayer
In Baldur’s Gate 3, the Balduran’s Giantslayer is one of the best martial weapons in the game and something you’ll want to get for martial classes like the Paladin, Fighter, and Barbarian. Depending on how you play through Act 3 it likely won’t be available until late in the game, but you shouldn’t skip it.
The Giant Form special ability allows you to grow in size, and your weapons deal an additional 1d6 damage, and you gain 27 Temporary Hit Points and Advantage on Strength Checks and Saving Throws. Combine the Giant Form with an Elixir of Cloud Giant Strength, and you are a walking juggernaut in BG3. And if you go up against a massive-sized monster, you get an advantage against them via Giant Slayer.

How to Get Balduran’s Giantslayer in Baldur’s Gate 3
To get the Baldurran’s Giantslayer Greatsword, locate the Dragon Sanctum within the Wyrm’s Rock Prison. From here, you will need to solve various puzzles explained in this guide Wrymway Trials guide in Act 3. Here is a quick breakdown of how to find and solve the Wrymway Trials:
- Locate the Wrym’s Rock Prison, accessed either via the Passageway next to Wrym’s Rock waypoint or through the crack in the wall outside the Fortress on the east side
- Find the wall with the Dragon Head torches. Light them with Lightning, not Fire.
- Chamber of Courage – Hold the torch and stay alive for 4 turns.
- Chamber of Strategy – Blast the Black King Piece with Lightning.
- Chamber of Insight – Shoot Suelto at the end of the path.
- Chamber of Justice – Cleanse shadow with Remove Curse. Place ‘The Cell’ painting into the Empty Niche.
- Enter the large double doors to the Dragon’s Sanctum.
Entering Wrym’s Rock Prison
The first step to acquiring the Baldur’s Greatsword is entering the Wyrm’s Rock prison via a small door in the main hallway. Simply head north from Rivington, at the start of Act 3, and enter. Depending on your dealings with Gortash, a fight might ensue immediately so be prepared.
Wyrmway Trials Entrance
After you’ve entered the prison area, move forward and left to find two dragon-looking pillars. You simply need to hit them both with lighting damage. This can be lighting arrows, Shock cantrip, or any spell. You need to do this roughly in a few seconds. Once completed, the hidden door will open and allow you to move through.
Wyrmway Trials
Now, you’ve entered the Wyrmay Trials, a series of four tests. The tricky one to locate is the Chamber of Insight, which you can access across a semi-transparent bridge. To fight Ansur the Dragon and obtain the weapon, you need to complete each trial. To start the trial, speak with the statue in each corresponding area. Let us show you how to complete each of them.
Chamber of Justice
Activate the Chamber of Justice status upon entering. Next, cast the spell “remove curse” on the judge character in the center. The simplest way is using Shadowheart as a Cleric who has this spell by default (life subclass). Next, three pictures are lying on stands in the center. Right-click on The Cell and select Pickup. Interact with the missing large tablet in the center which opens up a menu to place an item. Place the Cell picture and complete the Chamber of Justice.
Chamber of Courage
The Chamber of Courage requires you to pick up a torch and hold it for four turns without dying. During this time, you will be attacked by various elemental creatures. Here are some tips for completing Chamber of Courage in BG3:
- Have your lowest damage dealer, and highest survivability character pick up the torch
- Move to the center of the room and have a Cleric cast a Sanctuary spell on the torch carrier
- Do not attack or attempt to change weapons with the torch carrier as long as Sanctuary is active
- You can knock off enemies from the ledges with Roaring Arrows or Thunderwave
- Additionally, cast Globe of Invulnerability on top of the torch carrier which prevents all damage
- Be prepared for silence spells and elemental damage
- Use the crystals on the outside for elemental damage reduction
Chamber of Strategy
The Chamber of Strategy wants you to complete a randomized chest puzzle. If you have Gale in your party, he will essentially tell you how to solve the puzzle. The easiest way to solve the Chamber of Strategy is using lighting damage on the Black King Piece as it is vulnerable (takes 2x damage). This will kill it outright and solve the puzzle. We used Chain Lighting with Evocation Wizard build.
Chamber of Insight
Within the Chamber of Insights, look for 3 flying books throughout the room. You want to enter turn-based combat and move towards, loot, and read the book. This will require a slight of hand check and may require 3 characters to complete. The books tell you that Suelto is guilty, which you should attack in kill. You need to use a single target spell and only kill Suelto. Turn off Cull of the Weak or any passive area-based damage. We used Gale with Firebolt to kill him and advance the quest.
This should now unlock the Dragon’s Sanctum where you can get the Balduran’s Greatsword and helmet in Baldur’s Gate 3.
Fighting Ansur
After some dialogue and cut scenes, you’ll find yourself facing a very angry Ansur. If you take a moment to right-click and Examine him, you’ll see that he has Neocrotic, Lightning, and Poison Resistances. Additionally, he has an overall Magic Resistance, meaning you’ll want to rely more on your melee and ranged attacks to take him down. However, his Opportunity Attack feature means that melee can be hazardous unless you have a character using Polearms for additional reach.
There will be some Myrmidon ads that spawn during this encounter, but it’s best to ignore them for the most part. Taking Ansur down as quickly as possible with as much damage as you can muster is most important.
After two turns Ansur will begin to Gather Power, flying up into the air. You’ll see him generating Lightning energy. At this point, you’ll need to take a sharp look at his HP. If your characters can’t blast him out of the sky in one turn, then everyone needs to prioritize hiding behind the large white crystals in the area. Ansur will blast the whole area with his Stormheart Supernova and the crystals won’t necessarily promise full protection, as some of my party still died. Death Ward is a handy spell in this situation.
Hopefully, at least one or two of your characters are left standing after the blast and can finish bringing him down. Afterward, you can loot him and finally claim Balduran’s Giantslayer. Don’t forget to pick up the Helm of Balduran, sitting on a pedestal just to the back of the area where you brought down Ansur.
