This ring is made from a black metal that seems to absorb light into itself. It is etched with an ancient, forgotten language that only appears under moonlight.

Features:

1. Veil of Shadows: While wearing this ring, you can use an action to become invisible once per day. This effect lasts for 1 minute or until you attack or cast a spell.

2. Power of Shadows: The bearer of the ring gains a +2 bonus to attack rolls, damage rolls, and AC when they are in direct moonlight or darkness.

3. Shadow Shift: Once per day, the bearer of the ring can instantly move from any shadow to another shadow within sight, as if using the Dimension Door spell.

Drawbacks:

1. Curse of Shadows: The ring is cursed. Once the ring is attuned to its bearer, it cannot be removed without a Remove Curse spell or similar.

2. Call of Shadows: The bearer of the ring becomes sensitive to sunlight. They suffer disadvantage on attack rolls and perception checks when they are in direct sunlight.

3. Voice of Shadows: The bearer of the ring constantly hears whispers and voices that come from the ring. These voices can be disruptive and cause insomnia. When you take a long rest, roll a d20. On a roll of 8 or less, the voices disrupt your sleep and you will not get the benefits of the long rest.
