Deadly Trap Thursday - Inexorable Death Clock

Inexorable Death Clock (CR 17)

This bamboo and smoked black glass waterclock dominates an entire room, as precisely maintained and starkly beautiful as the clock itself. The walls are black lacquered oak, and the floor and low ceiling of the chamber are some soft, white wood. Water trickles into the water clock’s hundreds of tiny cups from a cleverly constructed array of pipes in the ceiling. One by one, the buckets fill, tip and empty their liquid into a smaller cup waiting below. Eventually, the water reaches the bottom of the clock, and disappears into a marble basin near the bottom of the large contraption.
