Candlestone (5e Equipment)
From D&D Wiki
Wondrous item, Rare
A small white stone that draws light towards it and focuses it into a stream
Anti prism. The candlestone constantly draws light towards it and focuses it into a narrow stream. It can slowly weaken anything with draconic ancestry.
I can't figure out how to make this work...
