Cold Fire

You cause one semi-permanent flame to absorb heat instead of produce it. Any flame that is within 30 feet of you and no more than 20 feet tall turns blue and deals 2d6 cold damage to any creature within 5 feet of it. Viable targets are campfires, a lit torch, a candle, a lantern, a burning enemy or even a wall of fire. The flame will remain cold and blue until extinguished. The damage of this spell is increased by 1d6 for every spell slot above 1st.
