You bolster yourself with animalistic power. Until the spell ends you are proficient with Constitution saving throws and gain resistance to bludgeoning damage from nonmagical weapons. 
As an action on subsequent turns you may invoke the power of nature to attack your enemies. Choose a creature within 30 ft of you. The chosen creature must make a Strength saving throw or take 4d6 piercing damage and become restrained by vines and roots that sprout from the ground. A creature restrained by this effect can reroll the saving throw at the end of its turn.
