D24.171 Pyramid of Colored Rays

A diorite cavern 100ft in diameter, 200ft in height. A steep pyramid 40x40ft in size and 70ft tall made of soft gallium stands at the center tipped with a large glass prism, which scintillates with changing colours that emit 2d6 rays of colored light randomly across the room, with their color corresponding to an element that deals 1d6 damage.

When a creatures approach the pyramid, more rays begin to focus on the creature.

The pyramid is difficult to climb without picks or claws as creatures may sink into the malleable gallium as they apply their weight on it.

The glass prism is a magical item that may be invoked to perform a similar effect except directed at targeted creatures and consumes a gallium ingot.
