Gem Of Brightness

This crystal appears to be a long, rough prism. Upon utterance of a command word, though, the gem's facets suddenly grow highly polished as the crystal emits bright light of one of three sorts.

• One command word causes the gem to shed light as a hooded lantern. This use of the gem does not expend any charges, and it continues to emit light until this command word is spoken a second time to extinguish the illumination.
• Another command word causes the gem of brightness to send out a bright ray 1 foot in diameter and 50 feet long. This strikes as a ranged touch attack, and any creature struck by this beam is blinded for 1d4 rounds unless it makes a DC 14 Fortitude save. This use of the gem expends 1 charge.
• The third command word causes the gem to flare in a blinding flash of light that fills a 30-foot cone. Although this glare lasts but a moment, any creature within the cone must make a DC 14 Fortitude save or be blinded for 1d4 rounds. This use expends 5 charges.

A newly created gem of brightness has 50 charges. When all its charges are expended, the gem becomes nonmagical and its facets grow cloudy with a fine network of cracks.
