Starting at 2nd level, your keen ability to assess tactical situations allows you to act quickly in battle. You can give yourself a bonus to your initiative rolls equal to your Intelligence modifier.
At 2nd level, you have learned to weave your magic to fortify yourself against harm. When you are hit by an attack or you fail a saving throw, you can use your reaction to gain a +2 bonus to your AC against that attack or a +4 bonus to that saving throw.
When you use this feature, you can't cast spells other than cantrips until the end of your next turn.
