Tulgorh

'''Tulgorh''', Aspect of Agony, is a Taken Ogre and the final boss of the Exotic mission The Whisper on Io. He spawns after the third boss dies and, unlike the earlier bosses, has an immunity shield.

The shield can only be removed by killing the pair of Taken Wizards near the back of the room. Once they are down, Tulgorh can be damaged. Repeat the cycle until he dies, then open the final chest to receive Whisper of the Worm and its crafting pattern.

The guide describing this encounter dates from around 2024, so the details may have changed in later updates.
