Cruelty

Weapon (longsword), very rare

This magical longsword is sharply serrated and seems to resonate with a dark energy that makes one’s skin crawl and numbs those around it.

You have a +2 bonus to attack and damage rolls made with Cruelty. In addition, if you roll a 20 on an attack roll with the weapon, you deal an additional 20 slashing damage, and the target must make a DC 20 Constitution saving throw or be paralyzed for 1 minute. A paralyzed creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.
