Slayer Sword

Shortsword
1d6 piercing - finesse, light
You gain a +2 bonus to attack and damage rolls made with this magic weapon.
The sword has 4 charges. If you score a critical hit against a creature that has fewer than 100 hit points, it must succeed on a DC 15 Constitution saving throw or be slain instantly as the sword tears its life force from its body (a construct or an undead is immune). The sword loses 1 charge if the creature is slain. When the sword has no charges remaining, it loses this property.
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.
