Ak-Norinthor: The Dagger of Lies

The Dagger of Lies is a very powerful (possibly Game Breaking) Artifact that was created by an Ancient dead deity and Paragon of Neutral Evil Alignment. It is sentient, devious and deceptive.  This is one in a set of 8 different Weapons that are sentient and aligned.  Once attuned the weapon's alignment overtakes the wielders alignment.  A Remove curse can break the attunement, however the wielder must willingly take steps to re-acquire their original alignment.

You gain a +5 bonus to attack and damage rolls made with this magic weapon. When you attack a creature that has at least one appendage with this weapon and roll a 20 on the attack roll, you cut off one of the creature's appendages The creature dies if it can't survive without the lost appendage. A creature is immune to this effect if it is immune to piercing damage, doesn't have or need an appendage, has legendary actions, or the GM decides that the creature is too big for its appendage to be cut off with this weapon. Such a creature instead takes an extra 6d4 piercing damage from the hit.  unlike a Vorpal Sword, this weapon does not ignore resistance to piercing damage.  The DM determines what appendage is cut off by the attack.  If thrown, this effect CAN NOT occur.  

The Dagger of Lies regains 1d6+6 charges when it is used to damage a target of any Good Alignment.  If the last charge is used, the Dagger becomes inert until it "tastes the Blood" of a Good Aligned creature again.

Proficiency with a Dagger allows you to add your proficiency bonus to the attack roll for any attack you make with it.
