Dagger of Cunning

Weapon (dagger), very rare (requires attunement)

This item appears to be a shiny, steel bracelet. While wearing it, you can speak its command word as an action or bonus action to transform it into a double-edged dagger that appears in your hand. Speaking the command word again reverts the item to bracelet form.

You gain a +2 bonus to attack and damage rolls made with this magic weapon. While holding it, you have advantage on Dexterity (Stealth) checks, and when you attack a creature that can’t see you, you maximize the weapon damage dice against the target.
