Cannot be tamed.
Located in Greatwing Roost, Bastion. This version cannot be attacked. You can activate this phalynx with a Discarded Centurion Core, which may be obtained by searching the area. The cores have been reported in the vicinity of Forgefire Outpost on Wowhead. Once you've activated the Clawguard it will morph into the black Corrupted Clawguard, which can be tamed or killed.
