Ring of Invisibility
Property: You can use an action to become invisible, along with your clothing, armor, weapons, and other equipment. The effect persists until the ring is removed or until you attack or cast a spell that affects a creature other than you. You can also mentally will the invisibility to end (no action required).
Examples of this simple gold band are sometimes engraved with a faint saying in Elven script, such as “The wind is unseen, yet it presses the grass as it flows.”
