Grove Spirit is a fourth eraNaturecreature. She is a powerful card that if used right can completely turn the tables to your favor on the field of battle. Her paralyzing beam can stun an enemy while another attacks. Since this is her main attack, so she can infinitely paralyze enemies. Healing song is useful when you have a massive army that's clashing with an enemy outpost. Play healing song, and all your troops will get a nice health boost in the midst of war.
