Celestial Light

"You touch one object that is no larger than 20 feet in any dimension. Until the spell ends, the object sheds bright light in a 40-foot radius. The light can be colored as you like. Completely covering the object with something opaque blocks the light. The spell ends if you cast it again or dismiss it as "a bonus action" Your affinity with light bolsters you, additionally: If you target an object held or worn by a hostile creature, that creature must succeed on a Dexterity saving throw to avoid the spell. Additionally, once per long rest, you can force a creature to make a Constitution saving throw. On a fail, the target is blinded until the start of your next turn.
