Starting at 2nd level, you have mastered the art of debate and know when a physical fight may be starting. You gain proficiency with persuasion, or one other skill of your choice if you already have proficiency in persuasion, and Whenever you make a persuasion check you may add twice your proficiency bonus to the roll. In addition, you can use your Spellcasting modifier for all persuasion checks as well as for your initiative rolls instead of the normal ability modifiers. 

Your ability to see things for what they can become rather than what they are has allowed you to learn how to augment your spells. Whenever you cast a spell that deals damage, you can change that damage type to  acid, cold, fire, lightning, necrotic, radiant, or thunder damage.

When you target a creature with a spell that uses a spell slot and the spell requires a Constitution, Dexterity or Strength saving throw, you can change the ability used for the saving throw to any other of your choice from that list.

Starting at 6th level, you have spent years solving complex mathematical equations, allowing you to shape your spells with precision. When you cast a spell of 1st level or higher that affects an area, you can increase or decrease that area by 10ft. You cannot use this ability to more than double a spell’s affected area or reduce the area below 5ft. 

Starting at 10th level, you gain new insights into the nature of causality. Whenever a creature casts a spell with a single target that you can see, you can use your reaction to choose a new target for the spell. The new target must be legal for that spell. Once you have used this feature, you may not use it again until you complete a short or long rest. 

Starting at 14th level, you’ve spent years studying philosophical paradoxes, which allows you to work seemingly impossible feats with magic. Whenever you would lose concentration on a spell for any reason, you may choose to maintain concentration instead, as long as you are not incapacitated. You may use this feature a number of times equal to your Spellcasting modifier, and you regain any expended uses after a long rest.
