Puzzles like the stone disc puzzle bg3 add layers of challenge, forcing you to think like a clever rogue or a wise cleric. According to Larian’s post-launch updates, these brain-teasers have sparked thousands of community discussions, proving their staying power even two years later. Let’s dive in and turn frustration into triumph.
Understanding the Stone Disc Puzzle BG3: What You’re Up Against

Picture this: You’re deep in the Goblin Camp, fresh from outsmarting Priestess Gut. You push through a hidden door, and there it is—a floor etched with interlocking stone discs, each marked with dots that glow like distant stars. These aren’t just decorations. They represent the eternal dance between Selûne, goddess of the moon, and her sister Shar, embodiment of darkness. In game lore, this puzzle guards the Selunite Outpost, a sacred site tied to Shadowheart’s personal questline: “Find the Nightsong.”
Why does it matter? Solving it unlocks the Underdark, a sprawling underground realm packed with myconid colonies, duergar strongholds, and pivotal plot twists. Skip it, and you risk missing key items like the Blood of Lathander or alliances that shape your party’s fate. Stats from player surveys on Steam show that about 25% of Act 1 completers get stuck here, often spending 30-60 minutes fiddling with the discs before seeking help. But with the right approach, you’ll breeze through in under five.
The puzzle features four circular plates: north, south, east, and west. Each has 12 positions—eight filled “full moon” dots (white) and four empty “new moon” voids (black, symbolizing darkness). Your goal? Herd all four black dots to the southernmost disc, aligning with the journal’s hint: “Cast darkness where it belongs at the bottom.” It’s like herding cats, but with celestial stakes.
The Role of Moon Phases in BG3 Lore
Baldur’s Gate 3 draws heavily from Forgotten Realms mythology. Selûne’s light battles Shar’s void, mirrored in the discs’ white and black symbols. This isn’t random—it’s a nod to D&D’s cosmology, where moon phases influence spells and events. For instance, clerics like Shadowheart gain bonuses under full moons. Understanding this backstory makes the puzzle feel less like a roadblock and more like a story beat. Fun fact: Larian hid similar lunar references in over 50 environmental details across the game, rewarding lore hounds with subtle Easter eggs.
Getting to the Stone Disc Puzzle BG3: Step-by-Step Location Guide
Before you spin a single disc, you need to reach the Defiled Temple. This isn’t a solo sprint—gather your party and prep for goblin ambushes. Here’s how to navigate there without alerting the whole camp.
- Enter the Shattered Sanctum: Head to the Goblin Camp in the West part of Act 1’s wilderness. Slip past the main gate by charming the guard (Persuasion check DC 10) or smash a cracked wall above the drunk goblins for stealth entry. The Sanctum is the northern pavilion, buzzing with branded prisoners and scheming leaders.
- Confront Priestess Gut: Find her in the southwestern chamber, brewing “tadpole cures.” You have options: Let her examine your parasite (triggers a boss fight later), poison her drink for a sneaky kill, or battle her outright with her ogre bodyguard Polma. Looting Gut yields the Priestess’ Key—essential for the next step. Pro tip: Save before this encounter; her Enlarge spell can turn Polma into a room-clearing terror.
- Unlock the Hidden Door: With the key, open the northwestern door in Gut’s chambers. Sneak past or dispatch any lingering goblins. This leads to a bedroom—search the cabinet right of the bed for the Selûnite Journal. Read it immediately; it drops the puzzle’s core clue about interlocking circles and bottom darkness.
- Descend to the Defiled Temple: Follow the eastern passage. You’ll hit a spiral staircase down to the temple proper. Watch for traps—spiked floors here have tripped up many a hasty explorer. The stone disc puzzle bg3 awaits in the main chamber, illuminated by a faint blue glow from the altar.
Travel time from camp entrance? About 10-15 minutes of gameplay, depending on your stealth level. If you’re role-playing a good-aligned party, consider freeing prisoners en route for extra XP and vendor discounts later.
Potential Pitfalls on the Way
Goblins patrol heavily, so use Misty Step or Invisibility if your caster has slots left. Low-level parties (levels 3-4) should stock healing potions—Gut’s fight alone can drain half your HP. Community data from Reddit’s r/BaldursGate3 shows 40% of players opt for the poison route, citing it as the “least messy” path.
Uncovering Clues: The Selûnite Journal and Hidden Hints
No puzzle solver worth their salt dives in blind. The Selûnite Journal is your Rosetta Stone, tucked in Gut’s cabinet as mentioned. Its cryptic lines—”Thus the interlocking circles will bring the full moons to match the stars, while casting darkness where it belongs at the bottom”—reveal the mechanics. White dots are “full moons” (light), blacks are “darkness” (void). Bottom disc gets the voids.
But there’s more. Scour the Goblin Camp for moon phase murals on walls near the main gate. These show ideal alignments: top disc all white, bottom all black, sides mixed. For eagle-eyed players, a high Perception check (DC 12) spots a faded fresco in the temple entrance depicting the exact solution. Ignore these, and you’re spinning discs like a drunk dwarf at a festival.
In broader BG3 terms, clues like this tie into the game’s 200+ environmental puzzles. Larian designed them to reward exploration—over 70% of players who read journals report fewer reloads, per a 2024 fan poll on Steam forums.
Where Else to Look for Lore Boosts
- Shadowheart’s Inventory: If she’s in your party, chat with her post-Gut. She comments on Selûne vs. Shar, hinting at the puzzle’s theme.
- Camp Overhearings: Back at camp, eavesdrop on companions. Gale might wax poetic about arcane alignments, giving indirect nudges.
These details aren’t just fluff—they build immersion, making your victory feel earned.
Step-by-Step Solution: Cracking the Stone Disc Puzzle BG3
Ready to roll? Position your main character on the discs—drag others away via the portrait bar to avoid accidental bumps. Face south for orientation: bottom disc is south, top is north, left west, right east.
Follow this proven sequence, verified across multiple playthroughs and community tests:
- Spin the South Disc 3 Times: This shifts initial blacks toward the center overlap. Watch the dots migrate—patience is key; each spin takes 2-3 seconds.
- Spin the West Disc 1 Time: Pulls a black from the side into position. If it clips oddly, nudge your character slightly left.
- Spin the South Disc 1 More Time: Locks in the first black. You’ll see the southern disc darken noticeably.
- Spin the North Disc 1 Time: Balances the top whites. This step often confuses newbies—resist over-spinning.
- Spin the West Disc 3 Times: Herds the second and third blacks southward. Pro tip: Zoom out for a full view; the game’s camera can trick you.
- Spin the East Disc 2 Times: Final adjustment for the last black. Hear that satisfying click? The door to the Selûnite Outpost creaks open.
Total spins: 11. Time: 1-2 minutes. If it fails, reset by leaving/re-entering the room—no penalties.
For visual learners, check this quick video demo showing the spins in action. It racks up over 47,000 views for good reason—clear, no spoilers.
Why This Sequence Works
Each disc interlocks, so spins affect neighbors. This order exploits overlaps to funnel blacks down, mimicking a sliding tile puzzle but with rotation. Math geeks note it’s isomorphic to a 4×3 grid permutation, solvable in under 12 moves optimally.
Bypass the Puzzle: The Sneaky Lever Trick
Hate spinning? Opt for the rogue’s path. Hug the northern wall east of the stairs—a DC 15 Perception check reveals a hidden lever behind illusory vines. Right-click and Lockpick (DC 15 Sleight of Hand). Success? Door opens instantly.
Best for: Astarion builds with 16+ Dexterity. Failure risks a trap (2d6 poison damage). Per IGN guides, 60% of sneaky players prefer this over spinning, saving 5-10 minutes.
Building for Success
- Gear Up: Thieves’ Tools from camp vendors boost your roll.
- Party Split: Send one character solo—less chance of alerts.
This method shines in speedruns, clocking Underdark entry in under 30 seconds from temple arrival.
Top Tips and Tricks for Mastering the Stone Disc Puzzle BG3
Even experts slip up. Here are battle-tested strategies to make it smooth:
- Isolate Your Solver: Drag companions’ portraits off-screen. One accidental step resets progress.
- Save Often: Quick-save before each spin. BG3’s autosave is reliable, but manual ones catch glitches.
- Use Enhancements: Pre-cast Guidance (from Shadowheart) adds 1d4 to checks. Owl’s Wisdom potion bumps Wisdom for Perception.
- Lighting Hack: Torchlight reveals faint disc engravings, hinting at moon phases.
- Companion Banter: Rotate Halsin into the party—he drops Selûne lore mid-puzzle, refreshing the clue.
From Polygon experts: Split the party every time—it’s a game-changer for precision. And remember, slowness is your friend; rushed spins lead to 80% of failures, per forum anecdotes.

Common Mistakes and How to Fix Them Fast
The stone disc puzzle bg3 trips up even veterans. Let’s troubleshoot the big ones:
- Over-Spinning Discs: You whirl south five times, scattering blacks everywhere. Fix: Count aloud—stick to the sequence. Reset by exiting.
- Ignoring the Journal: Diving in without reading feels intuitive but dooms you. Fix: Backtrack to Gut’s cabinet. It’s a 30-second detour.
- Party Interference: A companion bumps you mid-spin. Fix: Isolate immediately. Use the hotbar drag.
- Wrong Goal Assumption: Thinking you need half-moons or all whites bottom. Fix: Re-read the journal—darkness goes down.
- Missing the Lever: Low Perception blinds you to the bypass. Fix: Boost with Guidance or swap to a high-Wisdom character like Lae’zel.
Reddit threads like this one echo these woes—one player spent 90 minutes before realizing the simple “one away” tweak. Laugh it off; everyone’s been there.
