Temporal Double

You draw a version of yourself from a neighboring possibility. A duplicate of you appears in an unoccupied space within 15 feet. The double lasts for the duration.

The double has your AC, your saving throw bonuses, and 1 hit point. It cannot take actions of its own, but on each of your turns, you can command it to do one of the following as part of the same action you use to act:

• Move up to your speed
• Deliver one weapon attack using your spell attack modifier, dealing 2d8 force damage on a hit
• Cast one cantrip you know from its space
• Impose disadvantage on one attack made against you before the start of your next turn

The double cannot cast leveled spells, activate magic items, or concentrate on spells. If it takes any damage, it vanishes.
