Scrying Eye

A Scrying Eye is an item that allows a person to cast the Scrying spell for up to ten minutes. It can only be used once per day, and then cannot be used again until the next dawn.

Acquisition by Vox Machina
Vox Machina looted a Scrying Eye from the anonymous assassin who attacked Keyleth during Hotis's attempt to kill Vax'ildan. After being shoved out of a window by Keyleth's Thunderwave spell, the assassin tried to escape into the woods, only to be tracked down and killed by Galdric.
