Bramble Armor

A multitude of thorny vines burst from the ground and enwrap a willing, non armored creature you touch to form a suit of fibrous armor around the target. This armor is treated as medium armor with a base AC of 15 + Dexterity modifier (max 2). Normal penalties apply if the armored creature doesn’t have proficiency with medium armor. Any foe that strikes a creature encased in bramble armor with a melee attack takes 1d6 piercing damage.
