Zehir in Heroes 5

Every time a friendly stack dies, a group of elementals enters combat at hero's side. Number of elementals increases depending on hero level. In addition, Summon Elementals and Summon Phoenix spells casted by the hero are more powerfull.

Excitable, headstrong, and energetic are the sorts of words the older Mages use to describe Zehir. He chose to master elemental magic, figuring (correctly) that if he could control beings as fickle and powerful as elementals he would be well prepared for any magical struggle.Though the title First of the Circle was granted to the young Mage in the hopes of staving off political infighting during a crisis, the other wizards of the Circle quickly realized that it was only a matter of time before Zehir's skills surpassed theirs - time that is more likely to be measured in months than in years.
