The Dagger of Logoalth

Forged in the blood of innocents. Dedicated to an ancient forgotten death god. This viscous artifact is prized by thieves and assassins. Anyone found possessing one in civilized areas is quickly executed. Any non-cult members who have a dagger are hunted down and killed.
The Dagger of Logoalth is considered to be magical. It’s more potent powers only activate against living targets. The dagger gets more dangerous with each hit.
First Hit: Normal Damage
Second Hit: Double Damage
Third Hit and beyond: Target Saves or Dies. If the attacker misses then he must save or die.
And sorry this post was a little late but real life came around and bit me in the ass.
