Improving ability scores is crucial in Baldur’s Gate 3, and the Mirror of Loss is therefore an important item, as it can provide significant boosts. While the choice comes with a cost, the negative effects can be erased, making the Mirror of Loss an important location that you must visit.
However, like many things in Baldur’s Gate 3, it’s not entirely clear the approach you need to make, so we’re here to help.

Where to find the Mirror of Loss in BG3
The Mirror of Loss is located within a room behind the massive door in Viconia’s arena in the House of Grief. This means that you will have to fight one of the most challenging battles in BG3 to access the Mirror of Loss, but it’s well worth the trouble.
The door is locked by default, requiring you to relinquish some valuables to open it. Just beneath the door there is an altar and you can offer either highly valuable diamonds on a 1,000 gold in cash by placing it on the pedestal, thus opening the door. After you speak with Shadowheart‘s parents and decide whether or not to let them die, you can access the Mirror of Loss which is just behind the place where they’re chained.
How to use the Mirror of Loss in BG3

First, pray to the mirror by passing a Religion check, then pass an Arcana check to be able to trade one of your memories. As the scores for both are high, I highly recommend saving before you interact with the Mirror of Loss.
After doing both, you can sacrifice a memory to deduct two from one attribute and add two in another, and you’re able to remove the negative effect afterward by using the Remove Curse spell from Shadowheart.
Here are all the memories you can sacrifice, including the Forbidden Knowledge after reading the Necromancy of Thay:
- (Forbidden Knowledge) Part with the Forbidden Knowledge from the Thayan Tomb.
- Offer up memories of your strength – times when you triumphed, thanks to your raw power (-2 Strength).
- Give up memories of your youth, when your heart was carefree and your limbs were nimble (-2 Dexterity).
- Relinquish memories of fortitude and well-being, when body and mind held fast against all challenges (-2 Constitution).
- Surrender valued knowledge gleaned from books, scrolls, and tablets… words that left a mark on your mind, but no more (-2 Intelligence).
- Let go of some wisdom that time has bestowed upon you – old wounds, tough lessons, and fond memories alike (-2 Wisdom).
- Give away memories of when your charm stood to you – the applause of the swayed, the smiles of the beguiled, the kisses of the seduced (-2 Charisma).
- (Deception) You will not surrender any part of yourself. Invent a false offering to trick the mirror.
After taking a negative effect with the above choice, you can then add two from the following options:
- Claim memories of strength from a long-dead general, who marched under the banner of a vanished kingdom (+2 Strength)
- Help yourself to the memories of a seasoned thief’s most daring exploits (+2 Dexterity)
- Seize the memories of a barbarian, whose mind and body were tempered against hardship (+2 Constitution)
- Glean the secrets of a wizard who once stalked the libraries of Candlekeep (+2 Intelligence)
- Turn to the wisdom of a drow. Once of Lothe, then or Shar (+2 Wisdom)
- Warm to the guile of a bard who could charm even a dragon (+2 Charisma)
Should you sacrifice memories at the Mirror of Loss in BG3?

Yes you should, but some caveats do exist. For those who do not care about ruining their immersion with save scumming to always get the best possible result, the Mirror of Loss becomes a no-brainer choice that can only serve to buff your character.
While it might not seem like a worthy way to up your stats, the Mirror of Loss can both be exploited and used strictly to your advantage if you decide to save scum a little. Even if not, you can still get your important stats leveled at the cost of the ones you don’t really need, such as a Rogue relinquishing some Intelligence or Constitution to buff Dexterity.
