Her first attack is to rain several eggs from above and create poison fields from them. Her second attack is to swing a birdhouse down onto the arena using the Lickshot Lizard aspect of herself to crush the player. Her rage attack is to send out a line of tornadoes [2 if on last hit] using the Guardian Bird aspect of herself.
