Baldur's Gate 3 is filled with deeply buried secrets, but few match the grandeur of discovering the legendary undead dragon hidden beneath the city. Finding Ansur requires players to delve into Wyrm's Rock Prison and decipher a historical riddle left behind by ancient protectors. Unlocking this hidden encounter not only provides incredible narrative depth but also rewards adventurers with some of the most powerful equipment available in Act 3.
Navigating to Wyrm's Rock Prison
Before you can open the gateway to the dragon's lair, you must first gain access to Wyrm's Rock Prison. The standard route involves descending from the main fortress area, though players should expect high hostility if they have already crossed paths with Lord Gortash. Alternatively, clever parties can navigate through the city sewers to bypass heavy guard presence and find a direct route toward the prison cells.
Once inside the prison blocks, your primary goal is to locate a seemingly mundane dead end at the end of a dark hallway. Look closely at the stone walls to find two distinct lanterns shaped like dragon heads mounted opposite one another. This unassuming location holds the magical seal protecting the path forward into the deep caverns below.
Unlocking the Secret Entrance
To reveal the hidden passage, players must solve a riddle involving the dragon-head torches that guard the wall. You need to hit both of the stone statues with a lightning-based attack or spell to activate their hidden mechanisms. Utilizing simple cantrips like Shocking Grasp or basic lightning scrolls will easily complete this task without wasting high-level spell slots.
When successfully shocked, the torches will transform their standard orange flames into a distinct magical blue glow. Once both lanterns are active simultaneously, the solid stone wall will slide away to reveal a hidden tunnel. This doorway grants your party access to the trials of the Wyrmway, bringing you one step closer to the ultimate encounter.
Conquering the Four Elemental Trials
Stepping through the portal does not immediately bring you face-to-face with the legendary beast, as you must first prove your worth across four distinct chambers. The Chambers of Courage, Strategy, Insight, and Justice each present unique puzzles and combat challenges designed to test a hero's mind and physical resolve. For instance, the tactical chess puzzle requires precise movement or creative elemental destruction to pass safely.
Failing any of these trials will trigger waves of aggressive elemental enemies that can quickly exhaust an unprepared party. However, systematically completing each challenge unlocks the final inner sanctum where the legendary creature rests. Preparing your party with proper elemental resistances before entering these rooms ensures a much smoother journey through the depths.
Surviving the Legendary Battle
At the heart of the Wyrmway lies Ansur, a massive undead dragon that presents one of the toughest boss fights in the entirety of Baldur's Gate 3. It is highly recommended to ungroup your party and spread out immediately to avoid his devastating area-of-effect regular attacks. Players must also keep defensive spells ready to mitigate the massive lightning damage that charges up throughout the encounter.
Bringing characters capable of casting protective barriers can completely negate the dragon's ultimate destructive blast. Overcoming this immense challenge rewards your party with legendary loot, including the Helm of Balduran and Balduran's Giantslayer sword. Defeating Ansur marks a monumental milestone in your adventure, solidifying your status as a true hero of the realm.
