ESO Defender of Orsinium Achievement

How can I complete the Defender of Orsinium Achievement in the Elder Scrolls Online?
The Defender of Orsinium achievement can be unlocked by defeating four of the six world bosses in the Orsinium DLC:
  • Defeat Corintthac the Abomination
  • Defeat King-Chief Edu
  • Defeat Nyzchaleft
  • Defeat Old Snagara
  • Defeat Mad Urkazbur the Ogre
  • Defeat Zandadunoz the Ravager
It does not count for the Defender of Orsinium achievement if you defeat the same boss multiple times.
Where can I find the world bosses in Wrothgar?
  • Corintthac the Abomination
  • King-Chief Edu
  • Nyzchaleft
  • Old Snagara
  • Mad Urkazbur the Ogre
  • Zandadunoz the Ravager
Is it part of the ESO Base game or do I need a DLC or ESO plus subscription?
To be able to enter Wrothgar you need to own the Orsinium DLC or have an active ESO plus subscription
Are there any related quests with world bosses in Wrothgar?
I would recommend to pickup the Daily Repeatable world boss and maybe even the delve quests in Wrothgar. You can learn more about the Dailies in the Orsinium DLC in my Orsinium DLC Quest Guide
