Nine Lives Stealer

You gain a +2 bonus to attack rolls and damage rolls made with this magic weapon. **_Life Stealing._** The weapon has 1d8 + 1 charges.

When you attack a creature that has fewer than 100 Hit Points with this weapon and roll a 20 on the d20 for the attack roll, the creature must succeed on a DC 15 Constitution saving throw or be slain instantly as the sword tears its life force from its body.

Constructs and Undead succeed on the save automatically.

The weapon loses 1 charge if the creature is slain.

When the weapon has no charges remaining, it loses this property.
