Parrying Dagger, 2nd Variant (5e Equipment)
From D&D Wiki
Martial Melee Weapons
Also called a main-gauche, a dagger with a slightly longer and broader blade than usual, with a dull edge and sharpened tip, and an unusually long crossguard. It is used as a defensive side arm in dueling and fencing.
You gain a +1 bonus to AC while holding the parrying dagger, and it is not considered to be a weapon for the purpose of features such as the dueling fighting style. When you make an attack with the parrying dagger, you do not gain those benefits until the start of your next turn.
Parry: If an attack misses you by 2 points you can use your reaction to parry the attack giving you advantage or the enemy disadvantage on the next attack on the target you parryed. For example you have an 18 AC (with the dagger) and the enemy attacks you and roll an 16 you can use your reaction to parry the attack and gain advantage or give the enemy disadvantage.
