Block

Abilities: Strength, Constitution

You use your weapon, armor, or shield to block an incoming attack. When a creature makes a weapon attack against you but before you know the result of its roll, you can use your reaction to make a saving throw against a DC equal to 8 + the target’s attack modifier. On a success, you gain a +2 bonus to your AC against the triggering attack, potentially turning a hit into a miss. On a failure, the attacker rolls an additional damage die for this attack.
