Baldur's Gate 3 Arcane Tower walkthrough
Including how to easily disable Arcane Turrets.
The Arcane Tower in Baldur's Gate 3 contains some useful loot and interesting environmental storytelling, but exploring it is an optional activity not linked to any quest.
We do recommend you have a nosey inside though, as the loot contains some ingredients required for other side quests, and weapons that can come in very handy.
Although it seems like an impossible place to explore at first, there's actually some easy solutions and routes to take that won't harm your party that we've went over in our Baldur's Gate 3 Arcane Tower walkthrough below, which includes how to disable Arcane Turrets, and how to fix the Arcane Tower elevator generator.

Baldur's Gate 3 Arcane Tower location
The Arcane Tower is located in the Underdark, south of the Beach and Sussusr Tree Underdark areas, and west of the Selunite Outpost. You'll know you're close to it when you see a Bulete burrowing in the ground.
Go up the steps to the west of this area, where you'll be greeted by a nasty Arcane Turret guarding the Arcane Tower.
How to disable Arcane Turrets at Arcane Tower in Baldur's Gate 3
While you can sneak past the Arcane Turrets unscathed by manually entering turn-based mode (Shift + Space) and making liberal use of dashing, jumping, and hiding behind structures in the environment, there's a much easier solution.
To easily disable Arcane Turrets in Baldur's Gate 3 you need to use Sussur Blooms. These luminescent flowers are found growing in the Sussur Tree area just north of Arcane Tower, and can be dropped near Arcane Turrets to shut them down. This works because the Sussur Blooms disable magic, and the turrets are powered by magic.
If you haven't been to the Sussur Tree area yet, then be careful, as you'll have to fight Hook Horrors and a magic-user called Filro the Forgotten. For more information on this area and how it links to a side quest, check out our Sussur Bark location page.
Once the enemies are dealt with at the Sussur Tree, pick up at least 3 Sussur Blooms. This will temporarily disable your own magic capabilities, so head straight back to the Arcane Tower after picking them up, as taking any detours could be deadly.
There are two Sussur Blooms in the main Sussur Tree area, and one up the northern cliff near some poisonous gas. If you're having trouble picking up this flower without getting poisoned, drag and drop the Sussur Bloom near your character, then pick it up.
Back at the entrance to the Arcane Tower, ungroup by pressing 'G', then switch to turn-based (Shift + Space) and send the character with the highest movement speed towards the first Arcane Turret with the Sussur Blooms in their inventory. You can use dash to double your movement and reach the turret in one turn.
Drop one Sussur Bloom at this turret, then repeat dashing in turn-based to reach the second Arcane Turret on the stairs and drop another Sussur Bloom. Press 'G' to group up again now that the rest of your party can safely move in the area.
Notable loot: Before or after exploring the Arcane Tower, you should loot the small nook behind the first turret, as the locked check contains the Skybreaker uncommon light hammer with 1d4+1 attack damage that also grants the Searing Smite spell - you'll have to use a lockpick to open the chest. There's also some other items in this area like a letter, some Ingots, and a dirt mount you can dig up with a shovel for gold, a sickle, and a Scroll of Stinking Cloud.
You might want to ungroup again at the top of the Arcane Tower, as when you use a lockpick to open the main doors, there are two more Arcane Turrets ready to blast your party. We recommend sending one character back to the second turret and picking up the Sussur Bloom beside it, then using turn-based to dash back up to the entrance unharmed.
In the Arcane Tower entrance room, send the character with the most movement forward using dash in turn-based again, and repeat the Sussur Bloom tactic on both of the Arcane Turrets. Make sure to hide behind something when you need to end the turn.
Once the turrets are disabled, you can loot the boxes and chests here to get some Broken Machinery, and we recommend you read the Dusty Book in the northeastern corner.
We also recommend opening the door on the northside to get a Scroll of Mage Armour and to check out the Chest of the Mundane before moving on.
Baldur's Gate 3 Arcane Tower Chest of the Mundane explained
This magical chest looks like it contains some spectacularly unremarkable, worthless loot - but it's actually a magic chest that turns items into seemingly ordinary things like cups and plates.
When you add the chest's items to your inventory, you'll see that the Chest of the Mundane actually contains:
- Hearthlight Bomb
- Gold Ingot
- Scroll of Mage Armour
- Mystra's Grace (Uncommon boots that grants the Feather Fall spell)
- Scroll of Protection From Evil and Good
- x2 Silver Ingots
The best thing about the Chest of the Mundane, however, is that you can use it to store heavy items, as it converts everything you put in it to 0.5 weight items. Once you take it out, you'll get your loot back as normal.
So, right click on the chest and add it to your inventory if you want a boost to your inventory management.
How to fix Arcane Tower elevator generator in Baldur's Gate 3
Your goal while exploring the rest of the Arcane Tower is to fix the elevator generator so you can use it to get the best loot and find all items related to the story being told through the various books and notes found on each floor. It's important to read these notes to get all the best loot without starting a fight, so take your time!
Step 1 - Get to the floor below and loot
From the Arcane Tower entrance room, open the door on the southside, jump down to the blue mushrooms below, then jump from the mushrooms to the balcony on the next floor. This won't cause any fall damage.
The best loot in this area contains:
- Camp Supplies
- Timmask Spores
- Tongue of Madness
- A shovel
- Brimmed Hat
- Hat
You should pick up the shovel if you don't have one, but the most important thing to do in this second room is to read the Threadbare Book on a shelf in the western corner.
Once you're done looting, head out the door to the balcony on the southern side.
Step 2 - Get to the bottom of the tower
You'll have to either equip the Mystra's Grace boots and cast Feather Fall on your party or go solo for this next part of the journey. If going solo, we recommend sending somebody who is good at lockpicking, or can turn into a small animal like a rat (or conjure one). Give them a shovel too. Don't worry about splitting up, as you'll group up again before any potential battles.
On the southern balcony of the second floor, either use the Feather Fall spell, Potion of Feather Fall or the Misty Step spell to jump down to the ground floor below without taking damage. You can also jump without using any of these methods if your character has the health to withstand the damage.
If you're using Potion of Feather Fall make sure to jump immediately after taking it before its effects run out. We found this out the hard way...
Step 3 - Fix the elevator generator
You need a Sussur Bloom to fix the elevator generator in Baldur's Gate 3, but don't worry if you don't have one right now, as there are some Sussur Blooms growing in the Arcane Tower's garden.
Go to the end of the garden and pick up a Sussur Bloom, and you might also want to pick up the following ingredients and materials found in the garden:
- Bullywug Trumpet
- Laculite
- Bluecap
If your survival is high enough, you can also dig up the dirt mount found to the right of the small Sussur Tree and get:
- Weavemoss
- Acorn Truffle
- Scroll of Stinking Cloud
Now it's time to get back into the Arcane Tower, and there are two ways to do so:
- Lockpick the door
- Use a rat to crawl through the hole
Lockpicking requires high dexterity or boosts to your roll to work, but you need to either have a spell that can conjure a rat, or be able to turn into one yourself to get through the hole.
Once inside the bottom floor of the Arcane Tower, go to the generator by the elevator in the centre of the room and use a Sussur Bloom to restore power to the entire tower, which fixes the elevator.
If you're interested, the best loot available in this room includes:
- Laculite
- Sylvan Stone
- Lolth's Candle
- Dragon Egg Mushroom
- Swarming Toadstool
- Nightlight Frond
- Bullywug Trumpet
Now that the power is restored, go up the stairs and rejoin your party by using the elevator - but make sure you open the Gilded Chest on the small table opposite the elevator first! It contains the rare Uncovered Mysteries necklace that lets the wearer Detect Thoughts.
Once you've gathered your party, take the elevator up to the room above the entrance room and read The Roads to Darkness on the table in the southeastern side.
The best loot in this room contains:
- Gold
- Alchemists Fire
- Mage's Friend Ring (Uncommon - +1 to Arcana and Religion)
- Camp Supplies
- Carnelian Ring
- Scroll of Flaming Sphere
There's also a Handwritten Letter and An Open Letter on Oppression and Peacocks found near the table with The Roads to Darkness book that we recommend reading for more story, and an interesting tidbit about keeping bears as pets in Baldur's Gate.
If you're curious about the mysterious button near the bed, it doesn't do anything unless you equip a dog collar found by digging up a grave in the Sussur Tree area. We won't spoil what this does, but don't worry - you're not missing out on any valuable loot.
As long as you've read the Threadbare Book and The Roads to Darkness, you're ready to take the elevator up to the top floor and speak with Bernard.
Baldur's Gate 3 Arcane Tower Bernard riddle solution
At the top of the Arcane Tower you'll meet Bernard, a magical construct. Bernard turns hostile if you don't pick the correct dialogue options, so as long as you read the material listed in the previous section, you won't be harmed.
The correct riddle solution to Bernard's questions in Baldur's Gate 3 is:
- Or art thou friend, a rescue from my lonely wake
- How can I trust? How can I ever know? / How can I show myself, my darkest me?
This makes Bernard set the Guiding Light ring on the desk to the west, which you need to enter the Arcane Tower's basement.
Alternatively, you can fight Bernard if you want the Light of Creation uncommon Glaive, which has a 1d10 +1 attack with additional 1d6 Lightning damage, but also has a chance to stun the wielder.
The best loot besides the Guiding Light ring in this room contains:
- Broken Machinery
- Trap Disarm Toolkit
- Scroll of Magic Missile
- Scroll of Grease
- Scroll of Dimension Door
How to get to Arcane Tower basement in Baldur's Gate 3
With the Guiding Light ring equipped, walk back to the elevator to reveal a hidden button that takes you directly to the Arcane Tower basement.
Go up the stairs to pick up the Staff of Arcane Blessing beside a table and bookshelves. This is an uncommon quarterstaff with 1d8 (1d6) attack, the Bless Enchantment Spell, and Mystra's Blessing which grants and additional 1d4 to Saving Throws and Weapon Attack Rolls, and an extra 2d4 to Spell Attack Rolls.
We also recommend opening the Gilded Chest to the right of the staff, as it contains:
- De Hurst's Diary
- The Sparkswall (Uncommon ring - wearer can't be electrocuted and gets resistance to Lightning damage)
- x118 Gold
- Agate
- Elixir of Vigilance
- Scroll of Slow
- Greater Elixir of Arcane Cultivation
As for the rest of the room, the best loot besides the staff and gilded chest includes:
- Timmask Spores
- Scroll of Enlarge
- Scroll of Bestow Curse
- Scroll of Magic Missile
- Scroll of Grease
- Basilisk Oil
- Scroll of Scorching Ray
- Scroll of Fly
- Scroll of Web
- Scroll of Feather Fall
- Tongue of Madness
- Scroll of Protection From Evil and Good
- Scroll of Crown of Madness
When you're done looting the basement, you'll have completely explored the Arcane Tower! You can either take the elevator out, go out the door in the basement to get back to the room with the generator, or use a waypoint to fast travel to your next adventure.
