Orson in Heroes 5

All Zombies, Plague Zombies and Rot Zombies in hero's army gain +1 to their Attack and Defence for every two levels of the hero, starting on first level.

Somewhat lacking in charisma and natural authority, Orson realized that he was ill-equpped to lead troops that were capable of independent thought. In order to avoid having his orders questioned or ignored, he has spent years perfecting the creation of obedient Zombie troops. "Anything above the neck is useless" claims this Undead general.
