Atop the Shoulders of Giants
4 glass orbs with a feint blue light inside them.
Found within a vault aboard a Golirian ship, an Identify spell has revealed that these orbs, when shattered against a surface, will permanently affix a Daylight spell to that surface centered at that location. If affixed to a person, it will be affixed for a few days before the shedding of skin will cause the magic to falter and fail.
People exposed to a close-proximity shattering of an orb in low-light or dark conditions may be temporarily blinded.
