Circle of the Steel Beast

This is a faction of Circle of the Moon Druids that broke off to form their own circle dedicated to eradicating from the world,  those who abuse her natural resources for their own gain. They use the metal tools and armor of those who ruin and desecrate the world. 

Armored Wild Shape

When you choose this circle at 2nd level, you gain the ability to use Wild Shape on your turn as a bonus action, rather than as an action.

Additionally, while you are transformed by Wild Shape, you can use a bonus action to expend one spell slot to regain 1d8 hit points per level of the spell slot expended.

Circle Forms

The rites of your circle grant you the ability to retain the bonus given to you by your armor, even when in beast form. While in beast form, your skin takes on the properties of whatever armor you were wearing before transforming, becoming tough and leathery. Upon reaching this level, you gain proficiency in Medium Armor.

Tools of Destruction

At 3rd Level, you become proficient with all martial weapons. You may add your proficiency bonus to attack rolls made with martial weapons.

Steel Claw Strike

Your attacks in beast form count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage. You have also learned how to incorporate metal and magical weapons into your beast form. You gain bonus damage based on the weapon that you were holding when you transformed.

Steel Skin Forms

The rites of your circle grant you the ability to  incorporate stronger and sturdier materials into your beast form. Starting at 6th level, when you wildshape, you are able to incorporate metal armor into your beast form, your skin turning metallic and tough, gaining bonus AC based on the armor you are wearing. Upon reaching this level, you are also proficient in Heavy Armor

Shapeshift

At 10th level, you can use your Wild Shape to transform into a, non-variant, humanoid race other than your own, gaining the passive traits and ability bonuses of the chosen race while in that form.

Metal Destruction

By 14th level, you have learned to use magic to destroy the metal tools that are being used to destroy the land. You can cast the heat metal spell at will. Any non-magical. metal item that is affected by the spell used in this way is destroyed.
