Temporal Trickster

A Temporal Trickster can manipulate time to gain advantage in situations by viewing the future, slowing an objects temporal movement, and rewinding time to have a second chance at what could be a life or death scenario. Temporal Tricksters are usually not from the time period they exist in. Chronos, the God of Time, finds people throughout history who can utilize these abilities and infuses them with a fraction of his power, trapping them in another time. 

Chronos favours assassins and thieves to bear his gifts, believing they can use the powers of time best cause mischief. As the patron of Chronos becomes more proficient with the powers of time manipulation, they will gain access to more powerful skills, such as the ability to rewind themselves through time to redo up to 10 seconds of time. Evnetually, this skill can be improved to the point of rewinding the entire timeline back, with some risks, with only the Temporal Trickster and some selected allies remembering the actions that happened. 

Future Sight

Targetting one person, object, or creature, you can look into their future for 30 seconds. This can be used in combat to see the next action the target will do. This will give the target disadvantage on the action. 

This ability can only be used once per long rest. 

Accelerated Biology

You can speed up the effect of foreign substances in the body of your target, including yourself. You accelerate the speed of this subnstance by a multiple of five. 

This can mean that you decrease the time it takes for a poison to affect a target, or decrease the time a poison is affecting your body. It can also affect beneficial substances like potions, decreasing the time the target is affected by the potion. This effect does come with some side effects, when you accelerate the speed at which a potion affects you, you will take any damage the potion will do in a short amount of time, simply decreasing the time you are affected but not decreasing the damage. 

You can only use this ability once per long rest.

Redo

You can turn back time for yourself up to 10 seconds. This can be done once per combat encounter and up to 3 times per day out of combat. 

This replenishes any health you may have lost and any ammunition you may have used. You cannot do this while unconcious but can if you are grappled or incapacitated. 

Temporal Trajectory

You can slow down or speed up the temporal movement of an object that is used in an attack. This will add 5 to the attack roll if accelerating the attack or subtract 5 if the attack is being slowed. If the accelerated attack is double the target's AC, the attack results in a critical hit. 

This ability can be used twice per long rest.

Anomaly

You attempt to rewind the timeline by up to 20 seconds, selecting up to 5 other people. This ability creates ripples through the timeline, potentially causing mayhem.

You roll a D20 when using this ability, on a result of a natural 1 another effect occurs up to the DM's discretion. Some effects could be relatively harmless but others could be drastically dangerous. 

Examples of things that could occur; Time moving in a way you did not want i.e rewinding further than you wanted or moving forward instead. Or the ripple in the timeline could shatter it, causing a rupture and splitting the timeline causing irreversable changes in people and places. 

This can only be used once per day.
