Slow Maneuvers are those that take longer than a single Turn to execute. Some may be on the scale of a short or long rest, in which case they cannot be used in Combat. Other slow abilities, such as most rituals, have a more precise Execution Time specified in seconds, minutes, hours, or some other defined unit of time. These can be done during combat so long as the creature executing them uses the Sustain Ability at least once per turn.
