Exsanguinating Blade 2014
Weapon, rare, (requires attunement)
This double-bladed dagger has an ivory hilt, and its gold pommel is shaped into a woman's head with ruby eyes and a fanged mouth opened in a scream. You gain a +1 bonus to attack and damage rolls made with this magic weapon. When you roll a 20 on an attack roll made with this weapon against a creature that has blood, the dagger gains 1 charge. The dagger can hold 1 charge at a time. You can use a bonus action to expend 1 charge from the dagger to cause one of the following effects: - You or a creature you touch with the blade regains 2d8 hit points. - The next time you hit a creature that has blood with this weapon, it deals an extra 2d8 necrotic damage.
Properties
Finesse
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.
Light
A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.
Thrown (range 20/60)
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.
