Wheel of Stars

From Acquisitions Incorporated, page 222.

Description
Wondrous item, very rare (requires attunement).

While attuned to this device, you have a +1 bonus to Wisdom saving throws, and you can use an action to cast the Dancing Lights, Guidance, or Message cantrips.

Portent of the Stars. As a reaction when a creature you can see within 60 feet of you makes an attack roll, saving throw, or ability check, you make that creature roll a d10 and add or subtract the number rolled (your choice) from the roll. Once you use this feature of the Wheel of Stars, it cannot be used again until the next dawn.

Alter Gravity. As an action, you can cast Fly on yourself or you can cast Levitate (save DC 15). Once you use this feature of the Wheel of Stars, it cannot be used again until the next dawn.

Part of a Whole. While this component is not installed in the Orrery of the Wanderer, its magic might function sporadically or with unpredictable side effects, as determined by the DM.
