Dawnshard Brooch

Luminous Ward (1/Long Rest). Once per long rest, you can cast the shield of faith spell on yourself from the brooch, requiring no spell slot, components, or concentration check beyond the spell's own rules.

Blessing of the Sun. As a bonus action, you can activate the brooch to emit bright light in a 20-foot radius and dim light for an additional 20 feet, for 1 minute. While the brooch is glowing, undead and fiends have disadvantage on attack rolls against you.
