Chronokeeper

You have focused your training in the ancient art of Chronomancy - Time Magic. Although similar to Arcane Tricksters, Chronokeepers learn a very limited spectrum of magic, rather then the expense of enchantment and illusion spells learned by an Arcane Trickster. These rogue include only the most well trained spies, assassins, and adventurers.

Foresight

At 3rd level, you can add your Intelligence modifier to your initiative rolls, and you cannot be surprised whenever you are conscious.

Time Skip

• Starting at 3rd level, you gain the ability to leap back in time, undoing anything don’t against and anything you had done. At the start of your turn you can your action to leap back to the start of your last turn. When you do so, the following effects happen: 
• You return to the position where you started your last turn.
• Any damage that was dealt to you since the start of your last turn is reverted.
• Any damage that you dealt sine the start of your last turn is reverted including any conditions or effects that you have dealt.

If you use the feature 1 or more times within the last minute, you gain one level of exhaustion. If you use this ability out of combat, it works the same: your revert back to where you were 6 seconds ago, with the same hit points. You also can only use this out of combat once per long rest.

Supreme Time Skip

Starting at 9th level, you can choose to use your Time Skip feature without undoing damage of effects that you had caused.

Once you have used this feature, you can’t use it again until you finish a long rest.

Temporal Shift

At 13th level, you can cast Haste and Slow, using your Intelligence as your spell casting ability for these spells. Each of these spell can be cast once with this feature, and you regain the ability to cast them this way once you finish a long rest.

Time Lapse

When you reach 17th level, you have become a master at manipulating time. You can as a bonus action granted by your Cunning Action to re-apply all the damage you dealt since the start of your turn, doubling the damage in total.
Once you use this feature, you can’t use this feature again until you finish a long rest.
