This magical jewel has been passed down for generations in the Geldimer family, a noble clan of halflings whose youth have secretly moonlighted as vigilantes for more than a hundred years.
It can be used as a quick distraction or a means of concealing your escape. It's also handy as a quick strike against monsters vulnerable to radiant damage.
Created for day 4 of Jewel-ly, a month during which I'm challenging myself to create daily jewel/gem-related homebrews.
