Rampager

The ground trembles when the Rampager charges. Towering over lesser warriors, hulking with muscle and adorned with jagged bones, they roar—not a battle-cry, but the sound of pure rage. In Ugania’s wild hills, amid the Troll Lorddom’s rough banners, Rampagers are the calamity that precedes the storm.
  They slam clubs into earth, tearing stone from wall and limb from enemy, leaving chaos in their wake. Under their feet, grass flattens; armour buckles; shields splinter. Their presence distorts light—dust clouds rise in their wake—and foes falter even before the first blow, back-pedaling under the shadow of their approach.
