Parryer

You learn to use your offhand guilefully in combat, parrying an
opponent’s attack and countering with a punishing blow:
• Your Dexterity increases by 1.
• As a reaction to being hit with a melee attack from a creature
within your reach, you can make a Sleight of Hand check
against the attack roll. On a success, the attack misses, and
as part of the same reaction, you can make a melee weapon
attack against the creature with a finesse weapon. On a hit,
you can roll an additional damage die for the damage roll for
this attack.
