Tyrannomastyx hide

Tyrannomastyx hide is a Tier 10 Dungeoneering hide used to make Tyrannoleather armour. Players can obtain the hide either by hunting or killing a Tyrannomastyx or buying it from the Smuggler.Trapping is the more efficient method to gain hides instead of outright killing as more hides can be obtained while killing it may actually result in no hides.
