Bladeslinger

What some see a small and useless weapon, others see the dagger as a tool with endless potential. Bladeslingers are those people. Masters of the dagger, bladslingers train themselves to wield them with deadly proficiency. 

Devoted Daggers

At 3rd level, you have learned how to create a magical bond with your daggers. Immediately after making a thrown weapon attack with a dagger it returns to its sheath.

Additionally, you can add your proficiency bonus to the weapon damage when attacking with your daggers.

Knife Trick

By 7th level, you have learned how to strike with deadly precision. On your turn, you may use your bonus action to give yourself advantage on weapon attacks using your daggers until the end of the current turn. On a successful hit using this feature your target takes additional damage equal to a roll of the dagger’s damage die.

You can use this feature a number of times equal to your proficiency bonus, and regain all expended uses of it when you finish a long rest.

Stabbing Savant

At 7th level, your increasing proficiency with daggers allows you to make deadlier strikes with them. Your damage die with daggers becomes a d6.

Slinger’s Flurry

At 11th level, you learn to attack with such speed that you can turn a miss into another strike. On your turn when you miss with a dagger attack, you can make another attack as a part of the same action.

You can use this feature three times, and regain all expended uses at the end of a short or long rest.

Blade Barrage

At 15th level, you learn to strike at the defence of your allies. When an ally within 30 feet of you is attacked you may use your reaction to make a dagger weapon attack against the attacking creature.
