Cloak of the Seven Stars

Wondrous item, legendary (requires attunement)

This black robe is said to be a gift from the Pleiades themselves. It is embroidered with tiny white stars and seven large silver-blue stars . The stars are only visible in the dark. You gain a bonus to AC and Saving Throws according to the number of large stars on the cloak.

The birth of a star: While wearing this cloak, you can spend an action and one large star on your cloak to create a small star at your current location. The new star stays where you created it and provides dim light in a 5-foot radius.

You can't use this feature if no large stars are left on the cloak. Additionally, you can't create a star within 10 feet of another star created this way. You can use this feature 3 times a day. You regain all spent uses at dusk.

The death of a star: A created star dies after 1 week. It collapses. The collapse of a star triggers an explosion. Creatures within 10 feet of a star must make a Constitution save. On a failed save, a creature takes 2d6 radiant damage and is blinded until the end of its next turn. On a successful save, it takes half as much damage and is not blinded.

While wearing this cloak, you have a certain control over the stars you have created. You can spend an amount of movement equal to half your speed to teleport to one of the stars, absorbing the star back into your cloak. Additionally, you can use an action to kill off one or more stars. Lastly, you can as an action recall all stars into your cloak.
