School of the mind

a mind magic wizard is one that uses a special form of magic that isn't exactly categorizable as it is really just a way to excel in all  forms of magic rather than to specialize in one. mind magic only affects the wielder and their capabilities with all magic rather than enhancing their abilities with one specific kind. using their abilities, these wizards often use them diversify the usual forms of magic and alter them so they are stronger and more adaptable 

focus of mind

You can concentrate on two spells at once and when hit, you roll once for EACH spell you wish to maintain concentration on. You cannot concentrate on the same spell twice though (for example you couldn't concentrate on keeping gasseous form on your self and someone else but you could concentrate on keeping fly on yourself and gasseous form on someone else)

mental toughness

add your intelligence to your armour class

Full body activation

your mind is now fully able to control all parts of your autonomic nervous system and you can now use your body at full power and open your magical flood gates that your body held back to avoid strain or injury. You can now empower your damaging spells with extra damage by adding any amount of extra damage equal or lower to your current hp BUT you will receive half of the TOTAL damage back

eg) lets say you shoot a 3rd level fire ball and empower it, you have 30 hp and you decide to add it all. If you hit, they take 3d10 + 30 but after you must take 50% of that damage back. yjr extra 30 damage will be the same damage type as the spell

you can do this twice per long rest

Arcane adept

you can cast magic up to 3 times a turn (provided that they are not the same type of "activity") they cannot all be actions or bonus actions or reactions meaning that you could not cast two spells that required an action. In theory you could however, cast one spell that is an action, one that is a bonus action, and one that is a reaction.
