Most Precious Thing is the short side quest that unblocks Anca’s route to the library inside St. Tyna’s Convent. It hangs off the larger Echoes of Silenced Bells quest, and it exists because a squad of Brencis’s soldiers have barricaded themselves in the infirmary and refuse to open the door until you bring them a relic.
Quick answer: Take the Monastery Keys from the small shed beside the chapel, unlock the sacristy in front of it, loot The Relic of St. Tyna from the corpse inside, then return to the infirmary window. Handing the relic over or refusing it both open a safe passage to the library.
Most Precious Thing quest details
| Starting location | St. Tyna’s Convent |
| Quest giver | Brencis’s Officer |
| How to start | Speak through the window behind the infirmary during Echoes of Silenced Bells |
| Time cost | 0 time segments (the optional chapel search costs 1) |
| Missable | Yes |
| Rewards | 150 XP, plus The Relic of St. Tyna if you keep it |
The quest only appears after Anca leads you into the refectory and you get the objective to secure a safe passage to the library. From the Prioress’s balcony you can mark the infirmary, bell tower and chapel as points of interest, then drop down to the south to reach the courtyard.
The courtyard is full of undead nuns. They do not aggro instantly, but they will if you walk straight through them, so crouch or move with Haste while none of them are looking at you.
Every door on the infirmary is locked and the Monastery Keys will not open them. Go around to the back of the building and interact with the window. Brencis’s Officer explains that his men were sent to recover St. Tyna’s necklace and cannot return empty-handed, and offers access to the upper corridor that connects the infirmary to the library in exchange. Accepting starts Most Precious Thing.

The amulet raises maximum human health, boosts Witchcraft ability damage, lowers the health cost of Witchcraft abilities, and improves activation charge restoration from actions.
Tip: before you walk back to the infirmary, stop at the house on the western edge of the convent and read Campana Loquitur, Vel Introductio Pro Novitiis. It teaches Coen the bell signals, which matters for the alternative route below.
Give the relic to the soldiers or keep it
Return to the infirmary window with the amulet in your inventory and the officer gives you two options. Neither one blocks the library, so the decision is really about whether you want the amulet and the fight.
| Choice | What happens |
|---|---|
| [Here you go.] | Coen hands over The Relic of St. Tyna. The soldiers keep their word, clear the undead nuns and open the infirmary so you can use the upper corridor. |
| [I changed my mind. I’m not helping you.] | Three of Brencis’s soldiers attack. Kill them, keep the amulet, and the doors open anyway, giving you the same route through. |
If you simply walk away without resolving it, the soldiers turn up again later in Echoes of Silenced Bells to ask about the relic, and you face the same give-or-fight decision then.
How to confirm the quest is complete
Once the exchange resolves, a QUEST ENDED banner for Most Precious Thing appears on screen and the entry moves to your completed list. Open the journal and check that the objectives for the sacristy search and the return to the soldiers are struck through, and that the 150 XP has been paid out.

The Echoes of Silenced Bells objective to secure a safe passage for Anca also clears at this point. Going back to Anca and telling her to move costs an extra time segment on top of the three the passage objective itself consumes.
What locks you out of Most Precious Thing
There is one reliable way to lose the quest, and it involves the bell tower attached to the chapel. Ringing the infirmary signal sends the nuns swarming into the building, where they tear the soldiers apart. Do that before you speak to Brencis’s Officer through the window and the quest never becomes available. It also raises Coen’s infamy.
| Bell signal | Result |
|---|---|
| Chapel (3 tolls) | The nuns file in to pray, clearing the courtyard and the library route for Anca. |
| Infirmary (4 tolls) | The nuns break in and kill Brencis’s soldiers. Locks out Most Precious Thing if you have not spoken to the officer. |
| Dormitory (5 tolls) | The nuns gather on the west side of the courtyard but stay outside; this does not clear a safe path. |
If you have already used the infirmary signal, ring again for the chapel or dormitory to pull the nuns back out before you try to enter. Saving before you touch the bell rope is worth the few seconds, since the four-toll option is the only genuinely irreversible move in the sequence.
You do not need the soldiers at all if you would rather not deal with them. The chapel signal empties the courtyard on its own and lets Anca walk to the library, which makes Most Precious Thing purely optional. The relic is still worth the detour, though, and refusing to hand it over is the cheapest way to end up with an epic amulet before you head down into the catacombs.
