Shield of Vigilance

Armor (shield), rare (requires attunement)

This small, round shield is made of steel and has a pattern of radiating circles etched upon it. While holding this item, you have a +1 bonus to AC in addition to the shield’s normal bonus to AC.

After finishing a long rest, you can choose a type of creature: aberration, beast, celestial, construct, dragon, elemental, fey, fiend, giant, humanoid, monstrosity, ooze, plant, or undead. While holding the shield, you know if there is a creature of that type within 60 feet of you, as well as where the creature is located. This effect can penetrate most barriers, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.
