Prerequisite: Dexterity 15 or higher.

You have trained to use your weapon to parry, block or deflect an attack.

When you are wielding a finesse or light weapon with which you are proficient and you are hit with a piercing, slashing or bludgeoning attack by another creature, you can use your reaction to add a bonus to your AC for that attack, potentially causing the attack to miss you.

The bonus is calculated as follows:

• For a melee attack, it is equal to your proficiency bonus.
• For a ranged attack, it is equal to your proficiency bonus divided by two (rounded down).

If you are wielding a shield, this reaction can only be used against attacks that are not covered by the shield (on the non-shield side of the character).

This feat is a modified version of Defensive Duelist.
