Olog Graugs are a type of Graug in Middle-earth: Shadow of Mordor that have leathery skin and are slightly bigger then normal Graugs. Though uncommon, there are more of these types of Graug in Mordor, compared to Horned Graugs or the Legendary Graug.
- The oversized Olog Graug is a nigh-unstoppable juggernaut of wanton destruction, crushing, and mayhem. These behemoths grow to fifteen-feet tall or more, and their skin grows tough and leathery, making them extremely resistant to all manner of arrows, bolts, and bladed or blunt weapons.
- They're feral beasts, naturally combative, highly territorial, and ill-mannered. Graugs are uncommon in Mordor but pose a genuine threat to the Uruks, especially when their lairs are encroached upon. Even Trolls steer clear of the giant beasts, and when they do not, they tend to die horribly.
- Sauron has begun to use Graugs to cross-breed powerful Hill Trolls ; scaly monsters able to tolerate even noonday sunlight.
