You learn the mage hand cantrip. You can cast it without verbal or somatic components, and you can make the spectral hand invisible. If you already know this spell, its range increases by 30 feet when you cast it. Its spellcasting ability is INT (the ability increased by this feat).
As a bonus action, you can try to telekinetically shove one creature you can see within 30 feet of you. When you do so, the target must succeed on a Strength saving throw (DC 8 + your proficiency bonus + your INT modifier) or be moved 5 feet toward or away from you. A creature can willingly fail this save.
Starting at 2nd level when you select this school, you can use your action to conjure up an inanimate object in your hand or on the ground in an unoccupied space that you can see within 10 feet of you. This object can be no larger than 3 feet on a side and weigh no more than 10 pounds, and its form must be that of a nonmagical object that you have seen. The object is visibly magical, radiating dim light out to 5 feet.
The object disappears after 1 hour, when you use this feature again, or if it takes or deals any damage.

Starting at 6th level, you can use your action to teleport up to 30 feet to an unoccupied space that you can see. Alternatively, you can choose a space within range that is occupied by a Small or Medium creature. If that creature is willing, you both teleport, swapping places.
Once you use this feature, you can't use it again until you finish a long rest or you cast a conjuration spell of 1st level or higher.
