Elemental Avatar

Chosen by nature, you embody the great elements that shape the world!

When you use your wildshape to turn into a beast, you may add one of the following elements that lasts for the entire time while shapeshifted:

• Fire:  Flames wreath your new form.  You shed dim light in a radius of 15 feet around you, each attack against you deals fire damage equal to your proficiency bonus and you deal an additional amount of fire damage when you roll damage for an attack equal to 1d6 + your proficiency bonus.
• Water:  You shift into an aqueous torrent.  You have resistance to fire and cold damage, you have a swim speed equal to twice your walking speed, and you can move through a space as narrow as 1 inch wide without squeezing.
• Earth:  Your skin hardens into rock.  You gain temporary hit points equal to your Druid level, a burrow speed equal to your walking speed and gain tremorsense out to 15 feet.
• Air:  A cloud billows around you, a living storm.  You have resistance to bludgeoning, piercing, and slashing damage and as a bonus action, a gust of wind picks up, you may fly up to 20 feet before the end of your turn, you float gently above the ground.
