Whip of Agonizing Paralysis

You have a +3 bonus to attack and damage rolls made with this magic weapon. When this weapon reduces a creature to 0 hit points, the creature doesn't die. Instead, infernal runes appear as if carved into their flesh and they're healed to 1 hit point. They now have the paralyzed condition until the condition is removed by a Lesser Restoration spell or similar magic. When the condition is removed, the runes disappear. At the start of each of their turns while they're paralyzed, the creature suffers immense pain and gains a level of exhaustion.

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.

Reach: This weapon adds 5 feet to your reach when you attack with it, as well as when determining your reach for opportunity attacks with it.
