The scrying pool is a carved stone font filled with water located behind a secret door in the tomb. It radiates divination magic and serves as a tool for Withers to communicate with creatures outside the tomb and maintain contact with his tomb guardians.
Function
When any character gazes into the font, the water swirls and displays eerie light, revealing images from the perspective of a random tomb guardian patrolling the dungeon. The vision uses the guardian’s darkvision, rendering all images in black and white. The scrying effect continues as long as someone looks into the water.
Guardian Response
After 1 minute of being scryed upon, the tomb guardian becomes aware of the intrusion—unless the viewer wears an amulet of the black skull (from area 28). When detected, a flesh golem clad in plate armor (AC 17) physically emerges from the font itself and attacks everyone in the chamber, fighting to the death.
Recharge
Once a tomb guardian manifests from the pool, the scrying power ceases to function until the next dawn.
