Mushroom Fighter

You developed mushroom based fighting skills that come in handy during battle.

• Mushrooms are connected to an unseen network of life and spring back up after being cut down. You add your constitution to your AC.
• A mushroom is always ready for you. Sending out spots it has become immune to before you even know it’s there. You add your constitution modifier to your initiative. 
• Mushrooms may take a lot of damage, but they’re rarely gone for good. You now get twice your constitution modifier per level when calculating HP.
