Fire Storm is an ability of The Princess and Ranger Rayna avaiable at the fifth upgrade and RoboTurkey at the third upgrade.

Fire Storm rains fire balls onto all on screen enemies and does damage to them equal to 50% of their maximum health. If the Magnify ability is selected immediately prior to Fire Storm, then 75% damage is done.

This only operates if The Princess,RoboTurkey or Ranger Rayna is present in the current formation.
