Ankh of Aten

This golden ankh is about 12 inches long and has 5 charges. While holding the ankh by the loop, you can expend 1 charge as an action to fire a beam of brilliant sunlight in a 5-foot-wide, 60-foot-line from the end. Each creature caught in the line must make a DC 15 Constitution saving throw. On a failed save, a creature takes a5d8 radiant damage and is blinded until the end of your next turn. On a successful save, it takes half damage and isn't blinded. Undead have disadvantage on this saving throw. The ankh regains 1d4 + 1 expended charges daily at dawn.
