D24.133 Hall of the Tetravase

 An odd contraption 60ft in height and 50x50ft size constructed in a 200x200ft room. The floor is of Olivine brickwork and partially flooded with water 5 inches in depth. The contraption comprises 4 tall brass vases ornamentally carved with curved flourishes depicting waves.

Climbing to a vase reveals that the interior is far deeper than it appears. A rune of water is carved 300ft deep, which when undone with arcane knowledge causes the vase to begin filling with more water until it overflows.

Should the undoing fail, 2d6 water elementals manifest around the rune to protect it.

All water that overflows from the vases will naturally flow out from the Hall into other parts of the dungeon connected to it.
