Slow Time

*Requirement: Chronurgy Wizard; Character 12th level

After frequent manipulation of the sands of time you learned how to manipulate its flow, but at a great cost to your stamina. Once per day, as a bonus action, you can cast the spell Time Stop but you only gain 1 extra turn instead of the normal effects. It otherwise functions like the original spell. After the effects of the spell end you gain one level of Exhaustion.
