Orb of Remote Casting

Wondrous item, uncommon (requires attunement by a wizard)

This orb made of lavender crystal glows faintly, and gently hovers in place when left alone. As a bonus action, you can throw this orb to a space within 20 feet, where it hovers in place for 3 rounds.

During this time, you may cast spells using the orb as the point of origin rather than yourself, including spells with a range of touch. At the end of the three rounds, the orb stops glowing entirely and returns to your hand. In order to use the orb again, you must complete a short or a long rest.
