Glass Dagger

It has 5 charges, and it regains 1d4+1 charges at dawn. As a bonus action, you can spend a charge to cause the dagger blaze with light for 1 minute. While lit, the dagger sheds bright light in a 15-foot radius and dim light in an additional 15 feet. If you hit a creature while it's lit, it takes an extra 2d4 radiant damage and must succeed a DC 10
CON saving throw or be blinded for 1 minute.
