Level 3: Arcane Deflection
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 unless the spell is cast without expending a spell slot.
Level 3: Tactical Wit
Your keen ability to assess tactical situations allows you to act quickly in battle. You have Advantage on Initiative rolls.
Level 6: Power Surge
You can store magical energy within yourself to later empower your damaging spells. In its stored form, this energy is called a Power Surge.
Free Preparations. You add the Counterspell and Dispel Magic spells to your spellbook for free, if they weren’t there already, and you always have them prepared.
Number of Power Surges. You can store a maximum number of Power Surges equal to your Intelligence modifier (minimum of one). Whenever you finish a Long Rest, your number of Power Surges resets to one. If you end a Short Rest with no power surges, you gain one Power surge.
Gaining Power Surges. Whenever you successfully end a spell with Dispel Magic or Counterspell, you gain one Power Surge, as you steal magic from the spell you foiled. You also gain one Power Surge when you reduce a creature to 0 Hit Points with a Wizard spell that used a spell slot, but only once per casting.
Spell Empowerment. Once per turn when you deal damage to a creature or object with a Wizard spell, you can spend one Power Surge to deal extra Force damage to that target. The extra damage equals your Wizard level.
Level 10: Durable Magic
While you maintain Concentration on a spell, you add a +2 bonus to your Armor Class and all saving throws.
Level 14: Deflecting Shroud
Your Arcane Deflection becomes infused with deadly magic. When you use your Arcane Deflection feature, you can cause magical energy to arc from you. Up to three creatures of your choice that you can see within 60 feet of you each take Force damage equal to half your Wizard level (rounded up).
