Magnifying Glasses with Light in Blue Prince – and Why You Desperately Need Them
If you’ve spent more than a couple of runs wandering Mt. Holly Estate, you know the drill. Doors open, rooms shuffle, and half the time you’re standing in front of a document with tiny, almost illegible text wondering what on earth you’re supposed to do next. That’s where the magnifying glasses with light come in – two separate but deeply connected items that can genuinely change how you play this game. We’re talking about the Magnifying Glasses with light option – called the Burning Glass. One lets you read what the estate is hiding in plain sight. The other sets things on fire. Together, they cover more ground than almost any other tool combo in Blue Prince. So let’s get into it.
What Blue Prince Is Actually About (Quick Refresher)?
Before getting into the specifics, it helps to understand what kind of game this is. Blue Prince, developed by Dogubomb and published by Raw Fury, dropped in April 2025. It’s a puzzle-roguelite hybrid set inside a sprawling manor called Mt. Holly Estate. You play as Simon P. Jones, a young man trying to claim his inheritance by locating the mysterious Room 46 – a room that doesn’t appear on any blueprint.
Every run, you draft rooms from random draws, place them on a 9×5 grid, and navigate through them with a limited supply of steps. When you run out, the day ends and you start fresh. You don’t keep items. But you do keep knowledge – and that’s the whole game, really.
Knowledge is the real progression currency here. The estate is littered with clues, hidden codes, invisible ink, stamps, and symbols that only make sense once you’ve seen enough of the picture. Tools like the Magnifying Glass are how you read that picture clearly.
What the Magnifying Glass Actually Does?
Here’s something a lot of players miss early on: the Magnifying Glass isn’t just a zoom tool. It’s practically a cheat code for the early game.
When you pick one up and then open any document – a letter, a memo, a piece of paper on a desk – it appears on the edge of the screen. You drag it over the page. And suddenly, text that was blurry or impossibly small becomes readable. Some sections are written in invisible ink that only shows up under the glass. Others have clues hidden in the margins, or codes printed so small they’re basically two pixels tall at normal resolution.
The Campsite lock code? You find it under the Magnifying Glass on a document. Stamps? Every stamp you examine through the glass gets permanently logged in the Scrapbook in the Library. That’s not just flavor – it’s useful.
And there’s a late-game moment, if you haven’t hit it yet, where not having a Magnifying Glass will genuinely make you want to restart the run. Don’t say you weren’t warned.
Where to Find the Magnifying Glass in Blue Prince?
This is where the RNG of Blue Prince makes things a bit unpredictable. The Magnifying Glass doesn’t have a fixed spawn. But there are reliable patterns worth knowing.
Common spawn locations:
- Inside closets and special item rooms (keep an eye on the Nook Room).
- On tables in reading-type rooms like the Archive or the Study.
- The Commissary sometimes sells one for 4 gold – or you can place a special request at a Terminal to guarantee it appears there.
- The Garage, specifically inside the Car Trunk, after you obtain the Upgrade Disk (you’ll also need the Car Keys).
- The Spare Room, when it upgrades to Spare Foyer or Spare Master Bedroom.
- The Trading Post may offer it as part of a trade.
- Mail Room packages can occasionally contain one.
One important note: on Day 1, the Magnifying Glass is actually removed from the global spawn pool unless you’ve activated Veteran Mode. So if you’re a new player frustrated that you can’t find one – that’s intentional design, not bad luck.
The Terminal special request method is the most reliable approach once you’ve figured out how Terminals work. If you need the glass on a specific run, that’s your safest bet.
Burning Glass: Magnifying Glasses with Light, Literally
Here’s where things get interesting. The Magnifying Glass on its own is already valuable. But combine it with a Metal Detector at the Workshop and you get something entirely different – the Burning Glass.
The Burning Glass is classified as a contraption, meaning it’s crafted rather than found. It doesn’t do what either of its components does. It won’t detect metal. It won’t help you read documents. What it does is generate concentrated heat – enough to light candles, ignite fuses, melt ice, and burn through certain surfaces around the estate.
The description in-game – “can ignite certain surfaces and light candles” – undersells it a bit. There are dozens of things you can do with this tool. Players are still finding new uses.
How to Craft the Burning Glass?
You need three things:
- A Magnifying Glass (or Looking Glass – same item).
- A Metal Detector.
- Access to the Workshop.
Draft the Workshop room, head to the workbench, combine both items, and the Burning Glass appears. Pick it up. That’s it. Straightforward in execution, though getting all three pieces in the same run can take some patience depending on what the estate decides to give you.
If you somehow can’t craft it, there’s one alternative: a late-game secret shop sells a Torch, which functions identically to the Burning Glass. But that’s a conditional find, and you shouldn’t count on it.
Every Known Use of the Burning Glass (Organized by Area)
This is the part you actually came for.
| Location | What You Can Do |
|---|---|
| Crate Tunnel | Light two wall-mounted torches to illuminate the tunnel, reveal a Note, and permanently add the Tunnel floorplan to your draft pool |
| Chapel | Light both candles on either side of the altar to permanently reveal the Keeper of Tithes (a Piggy Bank) – break it to reclaim all your donated chapel gold |
| Tomb | Light two pairs of candles – the first reveals an Allowance Token and the Diary Key, the second hides an Upgrade Disk |
| Freezer | Thaw all the ice to access frozen gems, keys, a hidden Prism Key, and a note from Herbert Sinclair (note: this resets on future days) |
| Reservoir Room | Light the candles to reveal secrets in the underground area |
| Apple Orchard | Use it on the Sundial base – burns it open so you can rotate the base and interact with the top |
| Trading Post | Ignite the dynamite fuse (carefully – pay attention to what’s nearby) |
| Underground tunnels | Light a circle of candles near the Tomb entrance and mine cart area |
The Chapel candles are a fan favorite early-game priority because the Keeper of Tithes payoff is permanent and straightforward. Light them once, break the piggy bank, get all your gold back. If you’ve donated anything to the Chapel hoping it would matter, it’s very satisfying.
Tips for Getting the Most Out of Both Items
A few things worth knowing before you head into your next run:
- The Magnifying Glass is lost at the end of each day, just like everything else. You can store it in the Coat Check to preserve it, but that costs a step slot and takes planning.
- The Burning Glass also resets daily, so candles you light don’t stay lit – except in the Chapel and Crate Tunnel, where certain effects are permanently applied once triggered.
- Some puzzle solutions require the Magnifying Glass specifically – there’s no workaround. The invisible ink sections, in particular, are completely unreadable without it.
- Lighting candles in a room sometimes requires not leaving mid-sequence. If you partially light a set and then exit, some effects won’t trigger properly.
- The Freezer thawing is temporary – items refreeze on future days. So plan to grab everything in that same visit.
Comparing Item Value: When to Prioritize Each
Not every run is the same, and sometimes you have to make a call between chasing the Magnifying Glass versus the Metal Detector and Workshop combo.
| Situation | Which to Prioritize |
|---|---|
| Early game, first 5 days | Magnifying Glass – the clues it reveals are foundational |
| Mid-game with Workshop access | Go for the Burning Glass – Chapel and Tomb give permanent rewards |
| Freezer run | Burning Glass specifically |
| Stamp collecting goal | Magnifying Glass – stamps only log when examined through it |
| Late-game critical puzzle access | Magnifying Glass – you’ll know when you need it |
There’s no wrong answer here, but the general advice from the community is that the Magnifying Glass is more broadly essential, while the Burning Glass is higher-impact for specific permanent rewards. If you can get both in the same run, absolutely do that.
What Players Keep Getting Wrong?
A few common mistakes that come up again and again in community discussions:
- Ignoring the Magnifying Glass because text “looks readable.” It’s not. Some clues are written in such low resolution that they’re invisible without it. Go back and recheck documents once you have one.
- Forgetting the Workshop requires drafting. You can’t just walk to a workshop – it has to be drafted into your current run’s layout. If you’re planning a Burning Glass run, factor that into your room drafting strategy.
- Burning the wrong thing at the wrong time. The Trading Post dynamite, in particular, can be wasted if you’re not paying attention to the surrounding area. Look before you light.
- Not storing either item in the Coat Check when you’re planning to use them later in the same run. Steps are limited; if you’re burning through rooms to find the Tomb, make sure you actually have the Glass when you get there.
FAQ
Where do I find the Magnifying Glass in Blue Prince?
It spawns in item rooms like the Nook Room, on tables in the Archive or Study, in the Commissary for 4 gold, inside the Car Trunk in the Garage, or occasionally in Mail Room packages. Terminal special requests are the most reliable way to guarantee one.
What is the Burning Glass and how do I make it?
The Burning Glass is a crafted contraption. Combine the Magnifying Glass (or Looking Glass) with the Metal Detector at the Workshop workbench. It can light candles, melt ice, ignite fuses, and burn certain surfaces.
Do lit candles stay lit between runs?
Most don’t. The Chapel candles and Crate Tunnel torches are permanent exceptions – once those are lit, they stay that way across future days. Most other candles reset.
Can I get the Burning Glass without a Magnifying Glass?
The Burning Glass itself requires the Magnifying Glass to craft. However, a Torch – available from a late-game secret shop – works as an alternative to the Burning Glass for lighting purposes. The Magnifying Glass itself remains obtainable through its normal spawn routes regardless.
What does the Burning Glass do in the Freezer?
It thaws all the ice, giving you access to frozen items – typically a Prism Key, Herbert Sinclair’s letter, an Upgrade Disk behind a hidden ice wall, and other collectibles. The catch is that the Freezer resets on future days, so you need to grab everything in one visit.
Is the Magnifying Glass necessary for completing Blue Prince?
Not always – the game often provides multiple routes to the same puzzle solution. But there are certain late-game moments where it is genuinely required, and several invisible ink sections can’t be read any other way. Treat it as essential rather than optional.
Can the Burning Glass be reused across multiple rooms in one run?
Yes. As long as it’s in your inventory, you can carry it across rooms and use it as many times as needed within a single run. It’s one of the most versatile items for exploration-heavy days.
Final Thoughts
Mt. Holly Estate doesn’t give up its secrets easily. That’s half the appeal. And magnifying glasses with light – whether you’re dragging the Magnifying Glass over tiny handwritten notes or torching candles in the Tomb – are some of the clearest examples of how Blue Prince rewards players who actually pay attention.
The Magnifying Glass teaches you to look closer. The Burning Glass rewards you for doing so. Between the two, you’re covering a huge portion of what makes exploration in this estate feel genuinely satisfying – not just room-to-room progress, but the slow, methodical uncovering of a place that has been deliberately hiding from you.
Don’t skip these tools. Don’t leave them on the table. And seriously – if you haven’t revisited old documents with the Magnifying Glass yet, you’re missing entire conversations the estate has been trying to have with you.
