Knife Mastery

Your skill with knives and other minisculely-sized blades has improved. You gain the following benefits.

• You gain +1 to attack rolls with daggers, which has a range of 30/90 ft. when held by you, unless it would otherwise be improved.
• As a reaction when you are holding a dagger and are hit by a melee attack, you can reduce the damage by 1d4 + your Dexterity modifier. If this causes the damage to be reduced to 0, the attack against you instead misses, and you can make an attack with the dagger against the target as part of the reaction.
• When you have advantage on an attack roll with a dagger and hit, you deal additional damage equal to your proficiency bonus.
