Balduran’s Giantslayer

In Baldur’s Gate 3 the Balduran’s Giantslayer is one hands down one of the best martial weapons in the game and something you’ll absolutely 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

The first steps toward getting Balduran’s Giantslayer is finding the location of Anur’s Lair and then completing the Wrymway Trials in Act 3. Check out our full guide for step-by-step instructions, but here is a quick breakdown of how to find and solve the Wrymway Trials:

  1. 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
  2. Find the wall with the Dragon Head torches. Light them with Lightning, not Fire.
  3. Chamber of Courage – Hold the torch and stay alive for 4 turns.
  4. Chamber of Strategy – Blast the Black King Piece with Lightning.
  5. Chamber of Insight – Shoot Suelto at the end of the path.
  6. Chamber of Justice – Cleanse shadow with Remove Curse. Place ‘The Cell’ painting into the Empty Niche.
  7. Enter the large double doors to the Dragon’s Sanctum.

Fighting Ansur

Baldur's Gate 3 Ansur Examine Resistances

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, which means that 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 adds that spawn during this encounter, but it’s best to just ignore them for the most part. Taking Ansur down as quickly as possible with as much damage as you can muster is most important.

Baldur's Gate 3 Ansur Stormheart Supermnova

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. Afterwards, 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.
