Essence of Clarity is a bottle that can be found in Baldur's Gate: Siege of Dragonspear.
Acquisition[]
Two possible bottles can be found in the Repository of Undeath. One is on a shelf to the west of the wooden chair hanging over the mists in the laboratory, and the other held by one of the undead horde behind the hidden door near the center of the map.
Function[]
Once the Scrying Pool in the Repository of Undeath is made functional by the installation of three Silver Scepters, each can be used to see an additional possible vision.
