D'nadia's one-of-a-kind gift goggles that turn Donut's Magic Missile into a focused, quadruple laser.
The Prism goggles are the custom benefactor-box gift Princess D'nadia has made for Princess Donut on The Iron Tangle — a signed, unique Prism Industries item Donut adores as much for the movie-star fashion as the power. Beyond protecting her eyes from blinding and enhancing dark/heat vision, they catch and focus any energy spell fired from the ocular region: Donut's Magic Missile becomes a laser she can split into four simultaneous beams, or store a shot's energy and add it to the next. Standing on a platform, she now snipes into four train doors at once, delighted to look just like her beloved Miss Beatrice.
Large, round, arm-less movie-star sunglasses/goggles magically affixed to Donut's face, making her look bug-eyed and glamorous, reminiscent of Beatrice's sunglasses.
Donut's unique laser-focusing eyewear and a major combat upgrade.
