Call Bibliolethe

6th-level conjuration (ritual)

Casting Time:1 hour

Range:500 feet

Components:V, S, M (a cornerstone belonging to a library, academy, or other place of learning)

Duration:10 minutes

If you cast this spell during a lunar eclipse, you bring the Wandering Bibliolethe to a location you designate within range.

Creatures entering the library (including you) must make a Wisdom saving throw.

On a failed save, a creature remains within the library for the duration. When the spell ends, each creature within the Bibliolethe must succeed on a Dexterity saving throw or remain trapped within the library while it travels to its next destination. A creature that previously failed its Wisdom saving throw has disadvantage on its Dexterity saving throw. If the spell’s duration overlaps with another creature’s casting of call Bibliolethe, make a Charisma check contested by the other creature’s Charisma check. If you win the contest, the Bibliolethe remains in place for the entirety of the spell’s duration.
