Arcane Dagger of Tricksters

Sneaky Redo: When you use your Sneak Attack feature, you can reroll all damage dice. You must use the new rolls if you use this feature. (2/day)

You gain a +1 bonus to Attack and Damage rolls made with this weapon. 

If you do not have the Mage Hand spell, you can cast the spell once per long rest. 

When you cast Mage Hand, you can cause the hand to create a ghostly copy of the dagger as a Bonus Action. As part of the Bonus Action, you can make a melee attack with the Mage Hand against a creature within 5 ft of the hand. The Mage Hand uses your proficiency bonus and your Dexterity modifier in its attack. On a hit, the target takes piercing damage equal 1d4+your Dexterity modifer.

As a Bonus Action on Your Turn, you can move the weapon up to 20 feet and repeat the Attack action against a creature within 5 feet of it.

Proficiency with a Dagger allows you to add your proficiency bonus to the attack roll for any attack you make with it.
