Vanguard

Deflect Blow
When you choose this archetype at 3rd level, while wielding a single weapon lacking the Heavy, Light, and Two-Handed properties, you can attempt to deflect an attack requiring an attack roll. As a reaction, you can contest the attack's damage by 1d10 + your Dexterity modifier + your Fighter level. If this total is equal to or higher than the incoming attack, the blow is deflected and/or the projectile is destroyed. If it is lower, the damage is only reduced by an amount equal to your Dexterity modifier.

Erudition
At 3rd level, you gain proficiency (or Expertise if already proficient) in one Intelligence or Wisdom-based skill or tool of your choice. At 10th and 15th level, you gain an additional skill or tool proficiency (or Expertise).

Flurry of Strikes
At 7th level, you can attack once with a held weapon lacking the Heavy and Two-Handed properties as a bonus action.

Improved Deflection
At 10th level, your Deflect Blow ability can be done twice between turns with one reaction, increasing to three times at 15th level.

Arcane Deflection
At 15th level, your Deflect Blow ability can be used against spell attacks.

Retaliation
At 18th level, when you deflect a creature's attack with Deflect Blow, you gain advantage on all melee attacks against that target until the end of your next turn.
