This weapon is a magic dagger disguised as a sewing needle. When you hold it and use a bonus action to speak its command word, it transforms into a dagger or back into a needle.
You gain a +1 bonus to attack and damage rolls made with the dagger. While holding it, you can use an action to cast the mending cantrip from it.
When making an attack with a finesse weapon, you use your choice of your Strength or Dexterity modifier for the attack and damage rolls. You must use the same modifier for both rolls.
A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.
If a weapon has the thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for that attack roll and damage roll that you would use for a melee attack with the weapon. For example, if you throw a handaxe, you use your Strength, but if you throw a dagger, you can use either your Strength or your Dexterity, since the dagger has the finesse property.
