Armored ogre

As you guess from the name, Armored Ogres are Ogres wearing durable battle-armor. They are rarely seen in Dragon Age: Awakening, which is the only place you find them... They serve as tough foes that are challenges to beat. One is fought in Amaranthine and one in the Siege of Vigil's Keep (Endgame), and one at the Dragonbone Wastes, so you will fight at least two Armored Ogres. Armored Alphas do exist as well.
