Your ancestry grants you the ability to take time from any point of your life to pay for your mistakes. When you take damage, you can instead elect to take that damage at a later time(up to 2 days). You can do this a number of times equal to your proficiency bonus. Your uses of this ability do not refresh at the end of a long rest. Instead, you immediately gain a use of this ability back when you take damage from this ability. Damage taken from this ability cannot be reduced in any way.

Your innate ability to slow time grants you an unnaturally fast walking and climbing speed. you can spend a sorcery point to take a bonus action instead of a reaction

your armour that was given to you as you were initiated as a Timekeeper gives you +3 to your ac, however you cannot don any more armor, lest be cast out of the Timekeepers

You can turn back time when you need to most. As a reaction to you witnessing a character make an attack roll or saving throw, you can force the character to roll a d20.
After seeing the roll, you can choose which die they use.
Whatever your choice, you cannot use this feature again until you finish a long rest.

At higher levels:
level 10, you can use this twice per long rest
level 15, you can use this thrice per long rest
level 20, you can use this five times per long rest
