Lightning Khopesh

This bolt-like blade crackles with electric energy. When you hit with an attack using this magic weapon, the target takes an extra 1d6 lightning damage. In addition, the first time you have advantage on an attack roll and miss using this weapon on each of your turns, the target takes 1d6 lightning damage as stray sparks leap from the blade to shock the target.

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.

Light: A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.

Proficiency: martial, scimitar Source: The Griffon's Saddlebag: Book Two p. 115 (Third Party)
