Leadership (Recharges after a Short or Long Rest). For 1 minute, the hero can utter a special command or warning whenever a nonhostile creature that it can see within 30 feet of it makes an attack roll or a saving throw. The creature can add a d4 to its roll provided it can hear and understand the hero. A creature can benefit from only one Leadership die at a time. This effect ends if the hero is incapacitated.
Parry. The hero adds 6 to its AC against one melee attack that would hit it. To do so, the hero must see the attacker and be wielding a melee weapon.
A mage guardian with the Master template applied to it. Mage heroes are formidable warriors and spellcasters. They can challenge even the most powerful of enemies, standing toe-to-toe with all manner of horrible foes, though they are especially good at fighting spellcasters. A mage hero is often one of, if not the most, powerful combatant on a battlefield, and their mere presence can make or break an army's morale.
