Armor of Midas

Upon casting any portion of your skin that you wish turns into solid gold. Any attacks made with your golden skin will deal 2 d8 bludgeoning damage and any attacks made on your golden skin will have 1 d6 subtracted from the amount of damage rolled and give you advantage on your next attack toward the creature that hit you. If you have 20 gold pieces then you can choose to expend the twenty gold to cast this spell without expending a spell slot. The twenty gold will not be reobtainable after the spell is casted.
