Teacher

There's an old saying, "Those who can, do; and those who can't, teach." Of course, that saying is completely erroneous when applied to those who practice the mystic arts. Wizard
teachers are often considered to be some of the most powerful practitioners around. Typically, they are feared by those who recognize their relationship with magic. Wizard teachers use their coaching powers to boost other spellcasters and improve the abilities of those around them.

Magical Expertise

Starting when you choose this tradition at 2nd level, you learn two languages of your choice.

You also become proficient in the Arcana and History skills. Your proficiency bonus is doubled for any ability check you make that uses either of those skills.

Advanced Studies

At 2nd level, your knowledge of magic extends beyond the arcane. Choose two 1st-level spells to learn from any spell list. You can cast each of these spells once at its lowest level,
and you must finish a long rest before you can cast it in this way again. Your spellcasting ability for these spells is Intelligence.

Master and Student

Starting at 6th level, your coaching bolsters your allies' spellcasting abilities. When a friendly creature that you see within 30 feet of you casts a spell, and the creature can hear you, you can use your reaction to give the creature advantage on its ranged spell attack roll or to give the target of the caster's spell disadvantage on its saving throw against the spell.

Once you use this feature, you can't use it again until you finish a short or long rest.

Aura of Concentration

At 10th level, while you or friendly creatures within 10 feet of you are concentrating on a spell, you and the creatures have advantage on Constitution saving throws to avoid breaking your concentration.

Aura of Magical Resistance

At 14th level, you and friendly creatures within 10 feet of you have advantage on saving throws against spells.
