Step-by-Step Instructions to Obtain the Treasure

To track down this elusive treasure chest, you‘ll need to flex your deduction skills and thoroughly explore the Knights of Favonius Headquarters in central Mondstadt City.

Specifically, here are comprehensive directions to obtain the Gift:

First, open your map and teleport to the Knights of Favonius Headquarters Waypoint. This transports you directly outside the headquarters entrance.
Walk forward up the short staircase towards the fancy arched double doors. Enter through the doors into the headquarters‘ main lobby.
The lobby has tall ceilings with banners decorating the walls. You may see some Knights walking around or doing duties. At the back left is the large formal statue of Barbatos.
Instead of going towards the big statue, look to your direct right after entering to find a singular door. Open this right door and head into the corridor beyond.
Follow this linear corridor, ignoring the first door you pass by. Continue to the second wooden door along the right wall.
Open the second door and step inside the room to find the treasure chest! It rests against the back right wall surrounded by desks and packed bookshelves.

Entering this storage room filled with texts makes it clear why the clue refers to a "Magus-Custodian of Books sanctum." But what does this title mean?

Who is the Magus-Custodian of Books?

This hint alludes to Lisa, the brilliant librarian and sorceress who works for the Knights of Favonius in Mondstadt. She serves as the headquarters‘ head librarian, maintaining and growing the Knight‘s vast book collection over the years.

Lisa has an office on the upper floors where she studies these ancient tomes, conducts magical research, and chronicles the organization‘s history. She likely secured the special gift among the shelves for you to now uncover.

As the Magus-Custodian of Books, Lisa‘s passion lies with gathering knowledge above all else. She has an intense curiosity towards celestial secrets that magic can unveil. This sanctum matching Lisa‘s book-filled workspace is the perfect place to store a gift.

Details on Lisa‘s Backstory

Lisa hails from Sumeru Academia, where she was a top graduate known for her extraordinary intelligence and magical capabilities. She clashed with the institution for restricting knowledge only to the elite and left to pursue freedom in her studies.

The prodigy joined the Knights of Favonius as their magical advisor and took over management of the massive library. Lisa possesses the rare ability to manipulate elemental ley lines using a magic known as Ley Line Monolith. With this immense power, she serves as both librarian and formidable protector of Monstadt.

As the Magus-Custodian of Books, Lisa enjoys curating the bountiful collection of books on everything from history and science to magic spells and alchemy. She also has a lazy side, preferring to use tricks to avoid physical labor!

Treasure Chest Rewards

After following the clues to Lisa‘s book-filled sanctum, opening the ornate treasure chest uncovered here rewards:

40 Primogems
6,500 Mora
4 Hero‘s Wit
4 Mystic Enhancement Ore

While only 40 Primogems may seem underwhelming, collecting all 8 treasure chests from Fecund Blessings adds up to a considerable amount. You can also expect similar resource bundles from the other chests.

Overall, the average haul from each Fecund Blessings chest is:

40-60 Primogems
5,000-8,000 Mora
3-5 Hero‘s Wit
3-5 Mystic Enhancement Ore

With all 8 chests, that totals 320-480 Primogems, 40,000-64,000 Mora, 24-40 Hero‘s Wit, and 24-40 Mystic Enhancement Ore!

Here is a comparison of Primogems earned from some other Genshin events:

Event	Primogems
Fecund Blessings	320-480
Graven Innocence	420
Fayz Trials	820-1770
Windtrace	1260

As you can see, Fecund Blessings offers a healthy amount of Primogems relative to other events. And those precious gems are so useful!

What You Can Spend Primogems On

Primogems are the rare premium currency in Genshin Impact used to acquire new characters, weapons, resources, and more. Here are some of the top ways to utilize your hard-earned Primogems:

Make Wishes – Spend Primogems on the rotating character event banners or permanent wish banners to get new characters, weapons, and other loot.
Resin – You can convert Primogems into resin to replenish your stock. Resin is needed to claim rewards from domains, ley lines, and bosses.
Genesis Crystals – Primogems can be exchanged for Genesis Crystals, which are used to purchase special bundles like character skins or the Gnostic Hymn/Chorus monthly subscriptions.
Acquaint Fate – Purchase Intertwined Fate and Acquaint Fate with Genesis Crystals to make wishes on the various banners.
Resources – Spend Primogems directly on Mora, Hero‘s Wit, weapon enhancement ore, and other ascension materials.

With so many invaluable uses, accumulating those extra Primogems from events like Fecund Blessings makes a big difference. You‘ll be well equipped to wish for your favorite new 5-star character, refill resin to keep grinding, or pick up that stylish character skin you‘ve been eyeing!
