Prism Lantern
This lantern has a triangular hatch and lens for its light to shine through. A small, clear prism floats at its center. While holding the lantern, you can use a bonus action to cause the prism to glow, shedding bright light in a 30-foot cone and dim light for an additional 30 feet from the lantern. You choose the light's color, using the table below. It remains lit for 1 hour or until you use a bonus action to end the effect. You can change the light's color using a bonus action.
If the lantern is shedding this cone of light, you can use an action while holding the lantern to point it in a single direction and speak its command word. Until the start of your next turn or until the lantern is moved (whichever comes first), whenever a creature that's within the lantern's bright light takes damage of a type associated with the light's color, that damage is reduced by 4d6, or half as much if the creature is in the lantern's dim light. Once the lantern has prevented 50 damage in this way, starting with the creature closest to the lantern each time, it can't be used again until the next dawn.

Echoing through the hall came wood on stone, as to the Burning King's throne came a monk. Despite the lantern in his hand, his eyes hid behind a blindfold, and a cane entered before him. The king expected heroics, but the monk instead tapped the lantern, igniting a brilliant red as he set it to the ground behind him and took a pose of meditation. In response, the king spat, "What plan you with that, old fool?" The monk smiled, "The better for you to see me." The infuriated king sprang his trap, his stored fire and fury erupting in a whirlwind that overwhelmed room and sight to imprison his victims as they burned in an agonizing, slow death. He could hear it now, the screams, the cries for mercy, the…silence, as the ash was lit by a halo of red, split by a standing silhouette. "And I am seen." As a cinder fell from the monk's unstained robe, the lantern at last guttered out. And with a flash from the cane's unseen blade, so too did the king.
