Crèche Y’llek is a Githyanki stronghold located inside the ruins of the Rosymorn Monastery. It serves as a sacred and military site where Githyanki warriors are trained and where their young, called Githyanki crechelings, are raised. It’s also a place of healing and spiritual guidance, overseen by a high-ranking Githyanki Inquisitor.
Lae’zel believes the crèche may offer a cure or answers regarding the mind-flayer tadpole infection. It’s also the place where she hopes to receive guidance from Vlaakith, the Githyanki lich-queen.

Crèche Y’llek Awakened Bonus with the Zaith’isk Chair

The Awakened permanent bonus will allow you to use any of your Illithid powers as a bonus action, which is a great boost if you are consuming extra tadpoles. Furthermore, it can be gained during your visit to Crèche Y’llek. But only if you try for it before you advance into the Inquisitor’s Chambers!
After you get inside the Crèche, head down the western hallway and go left to reach the Infirmary. In the back room, you will find the healer Ghustil Stornugoss in her office with the Zaith’isk Chair. Tell her of your infection with the tadpoles and she will direct you to use the chair.
Lae’zel will insist on using the chair first, but to earn the bonus, you must refuse and use it yourself. Once the device activates, you’ll need to pass three separate ability checks:
- DC 12 Intelligence Saving Throw
- DC 15 Wisdom Saving Throw
- DC 18 Charisma, Constitution, or Intelligence Saving Throw
Regardless of the outcome, the chair will break after the sequence. However, if you succeed, you’ll gain the permanent “Awakened” bonus, granting a powerful boost to your character.
