Dagger Savant

Your skill and experience with the dagger far exceeds that of the average user.

These maneuvers can also be used with dagger-like bladed throwing weapons such as shuriken or kunai.

When you make a melee or ranged weapon attack with a dagger, you may attempt to pin a Large or smaller creature to a wall or surface by catching their clothing with the knife's point. This maneuver can be used against creatures without clothing at the GM's discretion. Make an attack roll; if the attack hits, the target must make a Strength saving throw. (DC equals 8 + the attacker's proficiency bonus + the attacker's Strength or Dexterity modifier) On a failure, the target's speed is reduced to zero until the dagger is removed. The target can make another Strength saving throw as an action on its turn.

Instead of making a Dexterity (Stealth) check to hide yourself, you may make Dexterity (Sleight of Hand) check-contested by an active or passive Wisdom (Perception) check--to conceal your dagger. As an action, you may make a weapon attack with a concealed dagger against a creature that has not yet acted in combat. This attack has advantage.
