Beast Lord's Claws

You invoke the blessing of Malar, god of the hunt, predatory beasts, and the brutal aspects of nature. Your hands and forearms thicken and become hair- or scale-covered, and your nails lengthen and sharpen into deadly claws. They do not hinder your manual dexterity or spellcasting. 

These claws are light finesse weapons that deal 1d8 slashing or force damage (your choice), and you can use your spellcasting ability instead of Strength or Dexterity for the attack and damage rolls of attacks using them. While the spell lasts, you also gain advantage on Strength ability checks.
