Reverse Spell

As a time mage, you have gained the ability to reverse time after you cast a spell to repeat the same spell. Your action is used to cast one spell that is not a ritual or concentration spell. You use a spell slot and any resources used in the casting as normal when casting the spell. After your action you can then use your Bonus Action to repeat the spell targeting the same creature/s, this time not using any spell slots, or resources.

You can use this ability twice, and regain all expended uses after a long rest. If you use this feat again when you have no further uses, the feat still goes in affect. Although, after the use of your Action and Bonus Action to attempt this ability, there is a 70% chance the process of reversing time may fail, making you incapacitated until the end of your next turn. When a failure happens you cannot attempt until after you've long rested.
