Wizard Subclass: Chronomancer
A study of time
Chronomancers are wizards who study in the art of manipulating time to their will. Many chronomancers will spend most of their study time delving into the art of changing the flow of time and will be their life's work. Many chronomancers are obsessive about their studies usually due to past situations in life and wanting to change the outcome of the past but this also makes them prone to being secretive and reluctant to share the work they have done.
Temporal Savant
At 2nd level, the time it takes to record any spell is halved. The cost to record a spell however is the same.
Minor Temporal Flux
Beginning at 2nd level, you can affect an object you can see within 50ft that’s not larger than a 5ft in any dimension, not worn or wielded or sentient, and stop it for 1d4 minutes as a bonus action. If you wish, you can end this effect early with a bonus action. The object will conserve momentum and speed including the way it was traveling before being stopped. If anything interacts with the object, be that creature or object that is larger then the object held, the object will unfreeze.
You can use this feature at will
Chrono Retreat
Beginning at 6th level, you can affect the time around you. When you back out of range from a creature taking an opportunity attack in your melee range, you can use a bonus action to give it disadvantage on the attack roll. You only need to use this feature once if multiple enemies are taking opportunity attacks.
You can use this ability at will.
Quickened Body
Beginning at 10th level, you have gained the ability to slightly speed up your body. You can choose on a turn to gain an additional bonus action of which you may cast a spell in it if the spell has the action casting time.
You can use this feature 2 times per day
Major Temporal Flux
Beginning at the 14th level, you have begun to become a master at the uses of chronomancy. Your minor temporal flux can now affect objects smaller then a 15ft in any dimension and can be used multiple times by expending more uses to affect objects larger than the 15ft in a dimension. If you wish, you can affect an object larger then 15ft by making a constitution check DC (10 + number of additional 15ft to accommodate the largest dimension of the object).
Also, your body is now protected from being aged magically and you now age at 1 year for every 20 normal years.
