School of Manipulation

This school is generally a mixture of individuals who were specially taught by reclusive masters, or individuals who happened upon knowledge not meant for them. 
The school of manipulation specializes in illusion and transmutation magic, able to show no discernable nature between true physical change and illusory images. 
Wizards of this type are highly variable in their ability, some choose to focus illusion for deception, and others choosing to focus transmutation for the shifting of that and those around them. 

What all Wizards of Manipulation have in common, is the tenacity to adapt and change the situation they reside through cunning and preparation. 

Master of Change

Beginning when you select this school at 2nd level, the gold and time you must spend to copy an illusion or transmutation spell into your spellbook is halved.

Reality is Subjective

When you choose this school at 2nd level, you learn the minor illusion cantrip. If you already know this cantrip, you learn a different wizard cantrip of your choice. The cantrip doesn’t count against your number of cantrips known.

When you cast minor illusion, you can create both a sound and an image with a single casting of the spell.

You also learn the Transmutate cantrip. A spell unique to this school that allows one to modify small objects on a physical level rather than only visual.

Malleable Reality

Starting at 6th level, when you cast an illusion spell that has a duration of 1 minute or longer, you can use your action to change the nature of that illusion (using the spell’s normal parameters for the illusion), provided that you can see the illusion.

Additionally, you gain the ability Manipulate Matter, granting you a brief moment of control over a object or creature's makeup. See ability for details.

Deceptive Being

Beginning at 10th level, you can create an illusory duplicate of yourself as an instant, almost instinctual reaction to danger. When a creature makes an attack roll against you, you can use your reaction to interpose the illusory duplicate between the attacker and yourself. The attack automatically misses you, then the illusion dissipates. You can choose to do this after learning if an attack hits or not, but not after the damage has been rolled.
You can do this twice per short or long rest.

Additionally, you learn a transmutation and illusion spell of your choice. The spell must be of a level you can cast.

Handcrafted Reality

By 14th level, you have learned the secret of weaving shadow magic into your illusions to give them a semi-reality. When you cast an illusion spell of 1st level or higher, you can choose one inanimate, nonmagical object that is part of the illusion and make that object real. You can do this on your turn as a bonus action while the spell is ongoing. The object remains real for 1 minute. For example, you can create an illusion of a bridge over a chasm and then make it real long enough for your allies to cross.

The object can’t deal damage or otherwise directly harm anyone.

You also gain the ability Singularity, allowing you to create a point in space that warps reality momentarily. See ability for details.
