As the title of the thread implies; if you play firestorm when at low health it will go from character to character (randomly?) and if it kills the caster before it finishes it will immediately cancel itself without damaging the other characters. I literally damaged my cleric and K.O.ed my mage without even touching the enemy blobs or my warrior.

It may be something that doesn't always happen, unfortunately I didn't think to copy the battle log. I will be sure to next time I encounter something similar
