Delerium-Forged Scimitar

This sword has a small delerium sliver encased in glass and set in the hilt like a gemstone. The blade is made of meteoric iron infused with delerium dust, which causes it to softly glow with octarine light. You gain a +2 bonus to attack and damage rolls made with this weapon. When you make an attack with this weapon, you can use your spellcasting ability modifier, instead of Strength or Dexterity, for the attack and damage rolls. In addition, you can use this weapon as a spellcasting focus. When you roll a 20 on an attack roll made with this weapon against a humanoid, the humanoid must succeed on a DC 15 Constitution saving throw or take an extra (3d6) necrotic damage and gain one level of contamination.

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.
