How to use the Mirror of Loss in Baldur's Gate 3
Sell some memories for an ability score bonus.
The Mirror of Loss is one of the more confusing parts of Baldur's Gate 3's Gauntlet of Shar. Like me, you probably spent far too long exploring the room, turning candles off and on, before giving up and abandoning the broken mirror. The good news is that there's another Mirror of Loss in Act 3 and you can actually interact with this one properly.
If you've been to the House of Grief in the Lower City to complete Shadowheart's quest, you'll find this mirror in the Chamber of Loss on the lowest level of the cult's headquarters. If you play your cards right, the mirror will bestow you with an ability score buff, so, here's how to use the Mirror of Loss in Baldur's Gate 3.
How to use the Mirror of Loss
Once you interact with the Mirror of Loss in the House of Grief, you'll need to pass an Arcana check to be able to trade one of your memories. You should also pray to the mirror by passing a Religion check before you offer one up. If you've done both, sacrificing a memory will allow you to trade -2 in one ability score for +2 in another. You can also get rid of the -2 afterwards, which I'll explain lower down.
It's worth noting that you only have access to the top response listed if you've read the Necromancy of Thay and acquired the Forbidden Knowledge condition. The Deception choice also won't result in any bonus, so don't choose that.
Here are the memories you can sacrifice:
- (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 wisdoms 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 you've received your -2 in a chosen ability score, you can choose a +2:
- 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)
Once you've got both -2 and +2 in your chosen ability scores, you can use the Remove Curse spell from Shadowheart to get rid of the -2, which appears in the form of the Stolen Vigour condition. It's worth noting that if you aren't able to pass the Religion check praying to the mirror, it'll only give you -2 in an ability score and no bonus. In this case, you should definitely choose to sacrifice your Forbidden knowledge from reading the Necromancy of Thay, as that will let you choose a +2 even if you failed the Religion check.
