Bite of the Dragon

You shroud your arm in the image of a dragon made of loosely bound elemental energy before lashing out at a nearby creature, your hand forms the maw with your thumb as the lower jaw.

Choose acid, cold, fire, lightning, or poison and then make a melee spell attack against a creature you can reach.

On a hit, the target takes 4d8 damage of your chosen type then it must succeed on a Wisdom saving throw with a DC equal to the damage taken or become frightened until the start of your next turn.
