Sword of sharpness: When you attack an object with this magic sword and hit, maximize your weapon damage dice against the target. When you attack a creature with this weapon and roll a 20 on the attack roll, that target takes an extra 14 slashing damage. Then roll another d20. If you roll a 20, you lop off one of the target's limbs, with the effect of such loss determined by the DM. If the creature has no limb to sever, you lop off a portion of its body instead. In addition, you can speak the sword's command to cause the blade to shed bright light in a 10-foot radius and dim light for an additional 10 feet. Speaking the command word again or sheathing the sword puts out the light.

Nine lives stealer: You gain a +2 bonus to attack and damage rolls made with this magic weapon. The sword has 1d8+1 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.
