Warmage

From DevroWiki

Sometimes, desparate nations call for special practitioners of war. The Tribunal of Arcane Law understands the needs of Callandor, Drakenmoore, and the disparate city-states of Cauldor, and trains a special breed of mage whose sole focus is the intimate understanding of war magicks - spells that will have practical use on the battlefield. These warmages begin a rigorous training regimen at a very early age, until they are ready to enter the ranks of their military establishments or go out into the world as soldiers of fortune. Few choose this life willingly, but there are a select few that see the money to be made in war magicks.

This class is not considered open gaming content. It can be found in Complete Arcane, pg. 10, by Wizards of the Coast.
