Aquamarine Ring of Spell Extending

This gold and silver knuckle ring has a long boss shaped like an hourglass. Set within what would be the sand of the hourglass are two aquamarines in a triangular cut - one large and one small. While attuned to the ring, you can use a bonus action when casting a spell to do one of the following:

• If casting a spell of 2nd level or less, the spell does not require concentration to last its full duration, but ends if you are incapacitated.
• If casting a spell of 6th level or less that lasts 1 minute or more, the spell's duration lasts twice as long as normal, subject to the limits of concentration (if applicable).

Once used, the aquamarines turn from blue to gray and the ring's power cannot be used again until after a long rest.
