Amulet of Unveiling Eyes

This magical sphere-shaped amulet features a large eye on the front surrounded by many small eyes within which occasionally blink.
While wearing the amulet, you gain a +1 bonus to saving throws. In addition, when you cast a divination spell using a spell slot, you regain one expended spell slot equal to half your level (rounded down), and you must finish a long rest before you can regain a spell slot in this way again.

As a bonus action, you can choose a creature you can see within 120 feet and use the amulet to reveal certain information about the creature. Learn two of the following: a conditional immunity, a sense, or a speed and a damage immunity, a resistance, or a vulnerability of the chosen creature. Once used the eye closes and cannot be used again until the next dawn.

Notes: Bonus: Saving Throws, Buff, Jewelry
