Acceleration

You touch one creature or object and twist the flow of causality around it, causing its time to accelerate. A creature targeted by this spell makes a CHA saving throw, being affected by the spell on a failure. While affected this spell:

• Every round is experienced as 2 rounds. A creature takes actions as if it has a single turn.
• A creature's attacks have advantage, and attacks against it have disadvantage.

When cast at a higher level, the time that the target experiences in one round increases:

• 4th - 1 minute
• 6th - 1 hour
• 7th - 1 day
• 9th - 1 year
